Three months after a young Colorado mom was last seen alive, new details are emerging about what might have happened to Kelsey Berreth.
Berreth, 29, was last seen at a supermarket on Nov. 22 near her home in Woodland Park, police said.
Below is a timeline of the investigation so far:
Thursday, Nov. 22
Surveillance footage from Safeway supermarket showed Berreth shopping for groceries with her 1-year-old daughter about 12:30 p.m., police said.
“That’s the last time Kelsey was seen,” Woodlawn Park Police Chief Miles De Young would go on to tell reporters.
De Young also noted that Berreth’s fiance and the father of her daughter, Patrick Frazee, told investigators he saw Berreth that day when she handed off their child to him.
Sunday, Nov. 25
Berreth’s employer, Doss Aviation, received texts from her cellphone saying she would not be at work for the next week, police said. Berreth worked as a pilot instructor.
Investigators were able to determine Berreth’s cellphone pinged that day on a tower near Gooding, Idaho, about 600 miles from her home in Woodland Park.
Frazee told police he received a text from Berreth’s phone that same day. Investigators have not revealed what that message said.
Sunday, Dec. 2
Kelsey’s mother, Cheryl-Lee Berreth, reported her daughter missing after being unable to reach her. Cheryl-Lee reached out to Frazee, who called her back and said he hadn’t heard from her since she had last texted.
Officers with the Woodlawn Park Police conducted a community care takers search on Kelsey’s home, which was empty. Her cars, her clothes and her toothbrush all appeared untouched since Thanksgiving, authorities said.
Monday, Dec. 3
The Woodland Park Police Department sent out its first appeal to the public in the hopes that someone would have information about Kelsey’s whereabouts.
“Please contact the Woodland Park Police Department at 719-687-9262,” they wrote.
Wednesday, Dec. 5
Kelsey’s loved ones created the “Missing Mother – Kelsey Berreth” Facebook page to spread the word about her disappearance.
The Woodland Park Police note Kelsey had last been seen wearing a white shirt, gray sweater, blue pants that may have been jeans, white shoes and had a brown purse.
Thursday, Dec. 6
Kelsey’s family noted it would be out of character for her to not let anyone know if she planned on making flying cross-country, regardless of her experience in the air.
“She does not own a plane nor do we know of any local friends that she would borrow one from,” they wrote on Facebook. “I don't believe she has ever made a flight without filing a flight plan. We do realize that it is possible to rent a plane, but I believe someone would be missing it by now.”
Friday, Dec. 7
A prayer vigil was held for Kelsey outside her brother’s home in Tacoma, Washington. Friends and neighbors came together to show their support, holding candles and singing “Silent Night,” video of the gathering showed.
“Please keep praying!” her family said on Facebook. “We need to find Kelsey!”
Monday, Dec. 10
The Woodland Park Police Department was joined by Cheryl-Lee for a press conference to share what they know so far.
De Young said the department is working with numerous law enforcement authorities, including the Colorado Bureau of Investigation, the FBI and officials in Gooding, Idaho.
All planes at her place of work have been accounted for, and there is nothing that indicates that Kelsey flew somewhere.
No one has been identified as a suspect in Kelsey’s disappearance, De Young said.
He said that Kelsey’s fiancé, Frazee, was invited to the press conference, but did not come.
“That’s a question you would have to ask him,” De Young said of Frazee’s decision to not attend.
Frazee is cooperating with police and is watching over his and Kelsey’s young daughter, De Young said. Kelsey has never lived with Frazee, her mother told reporters.
“I’d just like to talk to you a little bit about Kelsey,” she said. “She’s not the kind that runs off. This is completely out of character.
“Kelsey loves her god, she loves her family and friends, and she loves her job,” Cheryl-Lee continued. “She’s reliable, considerate and honest. … She doesn’t run off, and someone knows where she’s at.”
Tuesday, Dec. 11
Woodland Park police released the last-known footage that captured Kelsey before she disappeared.
In the video, you can see the young mother enter the Safeway supermarket. She carries her daughter in what appears to be a car seat that she then placed into a shopping cart before walking further into the store, the video shows.
Thursday, Dec. 13
Kelsey's mother, Cheryl-Lee, spoke to NBC, saying she is hopeful her daughter will be found.
“I can’t think of anywhere she’s gone where she hasn’t told me,” Cheryl-Lee told NBC. “It’s just not in her character to do something, to just take off and be gone.”
Cheryl-Lee said she spoke with her daughter twice on Thanksgiving, including once when Kelsey needed the details of a recipe.
“Her voice was fine,” her mother said. “It was a normal day for her.”
Cheryl-Lee said her daughter did not live with her fiance, Frazee, but that they have a strong bond.
“The relationship has been good,” said Cheryl-Lee. “They’re loving.”
Frazee's attorney, Jeremy Loew, told NBC his client is cooperating with police. Frazee voluntarily released his phone to be searched by investigators and has provided cheek swabs for DNA samples, he said.
Frazee wasn't present at a press conference held on Kelsey's case Monday because he only learned of it an hour before, his attorney said, noting he would have gone had he more notice. Loew said he also advised Frazee against speaking publicly to avoid tainting the investigation.
Resolute that someone somewhere knows something, Cheryl-Lee said she's committed to remaining positive.
“I still know somebody knows where she’s at,” Cheryl-Lee said. “Somebody has seen her. There’s more information out there. Somebody just needs to realize, recognize, say something.
"In the back of mind, sure, there's a possibility something else could have happened," she continued. "But it does me no good to go down that road. And I don't think it does Kelsey any good either."
The Woodland Park community gathered that evening for a candlelight vigil at the flagpole at Memorial Park in a show of solidarity to Kelsey's loved ones.
"We just want to spread love and hope and let Kelsey and her loved ones know that we're here for them," vigil organizer Amber Overton told The Denver Channel.
The dozens of people who came together were joined by Kelsey's mother, as well as De Young, who told the crowd a reward is being offered for information in the case. Specifics were reportedly not provided.
Friday, Dec. 14
Law enforcement officers executed a search warrant at Frazee's home, officials said.
Deputies with the Teller County Sheriff’s Office cut the lock on Frazee’s gate in Florissant before beginning their search of his home Friday, KRDO-TV reported. More than 75 law enforcement officials participated in the search.
Officials said the search could take up to three days. Frazee was at the property and was not under arrest, deputies told KXRM-TV.
But Frazee was never asked to voluntarily participate in the search executed at his home Friday, Frazee's attorney told the news station.
“We encourage law enforcement to take whatever steps it deems necessary to find Kelsey Berreth and to be able to exclude Patrick Frazee as a possible suspect in this missing person investigation,” he said in a statement. "Mr. Frazee will continue not to participate in any interviews with the media and instead focus on parenting the child he shares with Ms. Berreth.”
Sunday, Dec. 16
Authorities completed the search at Frazee's home. It’s not clear what they may have found there, if anything.
The Woodland Park Police Department announced a $25,000 reward for any information about Kelsey's whereabouts. The reward came from an anonymous donor, authorities said in a press release.
Tuesday, Dec. 18
Investigators briefly returned to Frazee's property Tuesday, but police said the visit was a routine follow-up, The Denver Post reported.
Authorities said they were continuing to "make steady progress" and were following multiple leads into Kelsey's disappearance.
The warrant issued in the search is sealed and no details are available to the public.
As investigators continued their search for Kelsey, a friend of Frazee's came to his defense.
Sonja Oliver, who says she has known Frazee for five years, told Inside Edition, "I've always considered him to be a gentle soul. Soft spoken and just really down to Earth and practical."
Oliver said she “couldn’t imagine him doing anything that would harm anyone.”
When asked by Inside Edition if she believes he had anything to do with Kelsey's disappearance, Oliver again stated, “I just can't imagine Patrick doing anything like that.”
Frazee's attorney told Inside Edition his client and Kelsey's relationship was largely positive.
“Like most relationships it has ups and downs but for the most part it's a good relationship,” he said.
Friday, Dec. 21
Frazee was taken into custody about 7 a.m. local time and was charged with murder and solicitation to commit murder, Woodland Park Police Chief Miles De Young said at a press conference.
"Sadly, we do not believe Kelsey is still alive," he told reporters.
Investigators have not yet located Kelsey's body, but they believe she may have been killed in her Woodland Park home.
De Young said police had conducted multiple interviews that gave them enough information to implicate Frazee in her death and obtain a warrant for his arrest. A multijurisdictional task force made up of numerous law enforcement agencies, including the FBI, served the warrant at Frazee's 35-acre ranch in Florissant.
His and Kelsey's 1-year-old daughter was in protective custody Friday and will be reunited with her mother's family, De Young said.
Authorities have confirmed that Kelsey's cellphone is in fact in Idaho, but were not able to elaborate on how it got there.
Frazee is being held without bond and will appear in court Dec. 31.
Saturday, Dec. 22
Authorities in Twin Falls, Idaho, said in a statement that its officers helped the Colorado Bureau of Investigations and the FBI "to prepare and serve several search warrants as well as processing some items of evidence."
The department did not say what evidence may have been found.
Twin Falls' Sheriff Tom Carter and Police Chief Craig Kingsbury said in a joint statement, “We are pleased our organizations were able to provide the assistance and support requested by the FBI, CBI, and the Woodland Park Police Department.”
Thursday, Dec. 27
Frazee appeared in court, shackled and looking disheveled, for an emergency custody hearing regarding his daughter, Kaylee.
The judge granted temporary custody to Kelsey's parents.
Monday, Dec. 31
Frazee was formally charged with Kelsey's murder. The complaint, which featured little in the way of details, included three charges of solicitation to commit murder, as well as two charges of first-degree murder.
Fourth Judicial District Attorney Dan May said that the two murder charges represent two separate theories of how Kelsey was killed. One of the murder charges mentions an accusation of robbery, indicating she was killed during the commission of a separate crime.
The other murder charge alleges Frazee himself deliberately caused the death of Kelsey with intent to do so.
“Obviously, there’s only one murder in this case,” May told KMGH-TV. “Under Colorado law, we file separate counts under different theories of first-degree murder. We filed under two theories: One is deliberation for murder. And the other is felony murder.”
Thursday, Jan. 3
A report emerged that an Idaho nurse, Krystal Jean “Lee” Kenney, 32, was being investigated for possibly disposing of a cellphone belonging to Kelsey.
Friday, Jan. 4
Monday, Feb. 4
It's reported that Kenney, the nurse being investigated in connection to Kelsey's disappearance, will plead guilty to at least one count later that week.
Friday, Feb. 8
Kenney was charged with one count of felony evidence tampering and pleaded guilty after agreeing to testify against Frazee, KOAA-TV reported.
Prosecutors said Kenney destroyed evidence related to Berreth’s disappearance between Nov. 24 and Nov. 25, 2018. Authorities have not released information about the evidence Kenney allegedly destroyed. Court records containing details about the evidence that led to the arrests of Kenney and Frazee remain sealed.
“I learned that Patrick Frazee had committed a homicide on approximately Nov. 22 in Teller County," Kenney said in a statement read by 4th Judicial District Attorney Dan May at a press conference following her court appearance Friday, KOAA-TV reported. "I knew that law enforcement would be investigating that crime. I moved the victim’s cell phone with the intent to impair the phone’s availability in the investigation.
"I had no right or authority to move the victim’s cell phone that occurred between Nov. 24 and Nov. 25, 2018 in Teller County.”
As part of her plea deal, Kenney cannot speak to the media.
Kenney will be sentenced after the conclusion of Frazee’s trial and faces as little as probation, or as much as 18 months on prison. If the judge determines there was an aggravating factor in the case, her sentence could be up to three years. She is due in court for a review on June 24.
Officials would not comment on the nature of Kenney and Frazee's alleged relationship, nor would they discuss the status of the search for Berreth's body. Court records containing details about the evidence that led to the arrests of Kenney and Frazee remain sealed.
Friday, Feb. 15
Kelsey’s parents updated the wrongful death lawsuit they filed against Frazee, saying a custody dispute was likely a motive to kill their daughter.
“Upon information and belief, Frazee had motive to kill Kelsey in that he wanted full custody of [their daughter] KB and/or Kelsey to leave KB with him and Kelsey would not agree,” said the amendment, which was filed in a U.S. district court Friday.
The amendment, which was made to a January wrongful death lawsuit filed by Kelsey’s mother and father, Cheryl-Lee and Darrell Lynn Berreth, also alleges that Frazee “had an opportunity to kill Kelsey or have Kelsey killed in that he had her keys and, because he had her gun, she was vulnerable to an attack.”
Kelsey’s parents said in the court filing they grew concerned after their daughter didn’t respond to calls or texts for a week. Cheryl-Lee said she called Frazee Dec. 2 to ask about Kelsey.
“Frazee responded with ‘here’s the story …’ and proceeded to knowingly and deliberately communicate … false statements, misrepresentations, and/or calculated omissions,” the update said.
Frazee allegedly told Kelsey’s mother that he and Kelsey broke up on Thanksgiving, that Kelsey agreed to evenly share custody of their daughter with him and that when she didn’t respond to a text he sent, “he figured she had put her phone on do-not-disturb so that she could study.”
When pressed for more details, Frazee allegedly said “Kelsey may have flown somewhere with a friend or co-worker,” the amended complaint said.
At one point, Frazee allegedly told Cheryl-Lee he “had enough and wasn’t going to deal with things anymore.”
The Berreths have asked for a jury trial in the wrongful death lawsuit, which was filed in a federal civil court because Frazee lives Colorado, while Kelsey’s parents live in Idaho.
When reached for comment by CNN, Frazee’s attorney Ed Farry declined to respond to the allegations in the amended complaint, saying "any such response will be made through a court filing.”
Tuesday, Feb. 19
Colorado prosecutors alleged Frazee beat Kelsey to death with a baseball bat after trying unsuccessfully to persuade his new girlfriend to end her life. Frazee is accused of wrapping a sweater around Kelsey's head and bashing it in with a bat before burning her body in a water trough, according to testimony at a preliminary hearing, CNN reported.
Frazee allegedly tried convincing Kenney to steal powerful drugs they could use to poison Kelsey's coffee, investigators reportedly said. Frazee allegedly told Kenney he wanted her to “get rid of Kelsey,” saying Kelsey was a terrible and abusive mother to their toddler daughter as well as a drug user.
Police said Kenney told them Frazee gave her Kelsey's address and her photo, and Kenney drove to the 29-year-old flight instructor’s home after picking up Starbucks coffee. Kenney allegedly said she knocked on Kelsey's door and lied about who she was when Kelsey answered, but said she was unable to go through with the plan. Authorities said Kenney told them when she told Frazee she couldn’t poison Kesley, he grew angry.
It was apparently one of three instances in which Frazee allegedly tried convincing Kenney to kill Kelsey before he is accused of taking matters into his own hands.
Police said Kenney said that while she was not involved in the actual attack, which investigators believe occurred in Kelsey's apartment last Thanksgiving, she was involved in the coverup.
Gregg Slater, an agent for the Colorado Bureau of Investigation, testified Tuesday that Kenney said Frazee asked her to go to Kelsey's apartment to clean up blood. Frazee even asked Kenney to search for a tooth near a vent in the home, Slater reportedly said.
While she spent hours scrubbing the apartment, which she apparently described as “horrific,” Kenney told police she refused to help Frazee dispose of Kelsey's body and so he took it to a farm in Fremont County, Slater said. Frazee then allegedly left Kelsey's body, which he had stuffed into a black tote bag, in a stack of hay while he celebrated Thanksgiving.
"You don't know how hard it is to have Thanksgiving dinner after killing her," Slater said Kenney told them Frazee said.
Frazee later allegedly put the body in a water trough, where he doused it in gas and added wood before lighting it on fire, Slater testified. He is believed to have left the remains at either a dump or in a river, Slater said.
But police investigating Kelsey's disappearance said they found blood in her toilet, the outside of her bathtub, the bottom of a trash can, on the walls, the floor, a towel rack, the vanity and an electrical outlet.
The blood found matched a DNA profile developed with samples taken from Kelsey's family, Slater said.
Frazee on Tuesday was hit with additional charges, including tampering with a body and counts related to a crime of violence. He has not yet entered a plea.
Friday, Feb. 22
Investigators in Colorado are reportedly planning to search a landfill for Kelsey's remains, as well as look for any other evidence possibly connected to the missing mother.
Authorities on Tuesday will begin sifting through the Midway landfill near Fountain, beginning a search that could take several months to complete, sources told ABC News.
Waste Management of Colorado confirmed to ABC News in January the Colorado Bureau of Investigation contacted them “regarding a potential search at Midway Landfill.” The agency said it is fully cooperating.
