Body of Teen Thought to Be Missing After Mom, Sister Found Dead Is Discovered in Woods

The body of Kirsten Fritch was discovered Thursday, not far from where officers arrested her 21-year-old boyfriend, Jesse Dobbs, police said.

The 16-year-old girl missing after her little sister and mother were fatally shot in Texas has also been found dead, authorities said, and the teen's 21-year-old boyfriend remains a suspect in all three murders.

The body of Kirsten Fritch was discovered at about 12:40 p.m. Thursday not far from where officers arrested her boyfriend, Jesse Dobbs, two days earlier, the Baytown Police Department said.

Authorities found Dobbs in Shenanigan’s Bar in Texas City at about 9:30 p.m. Tuesday, hours after Fritch’s mother, Cynthia Morris, 37, and her sister, 13-year-old Breanna Pavilicek, were found murdered, police said.

Officers conducting a wellness check at their Baytown home discovered the mother and young girl had each been shot at least once, authorities said.

Morris’ car had been missing from the scene. It was later found across the street from the bar where Dobbs was taken into custody, police said.

"Baytown Detectives attempted to interview Mr. Dobbs about the murder; however, he refused to offer any details about the deaths of Cynthia and Breanna, or the whereabouts of Kirsten,” Baytown police said in a statement.

After searching for nearly two days, police discovered Fritch’s body in a wooded area north of the bar.

“A motive for the murders has yet to be determined as Mr. Dobbs continues to refuse to cooperate with detectives,” police said.

Dobbs and Fritch began dating after they met online, Fritch’s grandmother, Barbara DeRamus, told KHOU.

He moved into the family’s home not long after, but the teen’s mother wanted him out and did not approve of the relationship, DeRamus said.

“He just seemed like a lowlife,” she told the television station. “I thought, what was Kirsten doing with this idiot?”

Dobbs has not been charged in connection to the murders, but authorities said he is a suspect. He remains in the Galveston County Jail on a resisting arrest charge, authorities said.
