Teen Missing After 21-Year-Old Boyfriend Allegedly Kills Her Mom, Younger Sister

Kirsten Fritch, 16, has been missing since Tuesday, when her mother and younger sister were found shot to death in their Texas home.

A 21-year-old Texas man was arrested Wednesday for the murder of his much-younger girlfriend’s mother and little sister, a day after authorities put out an Amber Alert for the missing teenager.

Kirsten Nicole Fritch, 16, has been missing since Tuesday, when her mother and sister were found dead in their Baytown home.

Officers conducting a wellness check Tuesday morning discovered the bodies of Cynthia Morris, 37, and her 13-year-old daughter, Breanna Pavilicek, each shot at least once, officials said.

Morris’ mother had called 911, saying she had been unable to get in touch with her daughter or her granddaughters, and that her daughter had also not shown up for work, Baytown Police said.

The grandmother went by her loved ones’ home and when she found the front door slightly open, she called police, officials said.

Investigators determined that Morris’ car, a white, Chrysler PT Cruiser, was missing.

Morris’ older daughter, Fritch, was also nowhere to be found.

An Amber Alert was issued for the teen, who investigators said was last seen with Jesse Dobbs, 21, who authorities said was an acquaintance of Fritch’s.

But according to reports, the pair had been dating and Morris was against the relationship.

“Detectives are considering Mr. Dobbs a person of interest at this time and are concerned about the welfare of the 16-year-old,” police said Tuesday.

Dobbs was found with Morris’ car Tuesday night, authorities said.

A father-of-two and an avid user of social media, Dobbs wrote on Instagram: “I love my kids. I’m focusing on being a father.”

“Looking for the one,” he posted on Instagram 12 weeks ago.

But others said Dobbs seemed troubled, saying that he had recently threatened violence.

Neighbor William Baron told KHOU that Dobbs suffered from drug addiction saying: “He told me the other day that, ‘I am numb, I don’t care what I do, if I kill somebody, I kill somebody.”

Fritch is 5-foot-1, weighs 135 pounds and has brown hair and green eyes.

Anyone with information about this case is asked to contact Baytown Crime Stoppers at 281-427-8477 or the Baytown Police Department at 281-422-8371.
