The boyfriend of a 16-year-old Baytown girl found murdered last week has been charged in her death.

Jesse Dobbs, 21, remains in the Galveston County jail on a murder charge for the stabbing death of Kirsten Fritch. He is also being questioned in the murders of Kirsten’s mother, 37-year-old Cynthia Morris, and her younger sister, 13-year-old Breanna Pavilicek.

Police found the bodies of Morris and her youngest daughter in their Baytown home on Nov. 8.

Kirsten and her 2008 PT Cruiser were missing and an Amber Alert was posted. They named Dobbs as a person of interest.

Later that night, police found Dobbs at a Texas City bar. Kirsten’s car was in a parking lot across the street but there was no sign of her. Investigators say Dobbs was uncooperative and they charged him with resisting arrest.

After a two-day search, Texas Eqqusearch volunteers found Kirsten’s body in a wooded area north of the bar where Dobbs was arrested.

Dobbs started dating Fritch after they met online. He moved into the family's home a few weeks ago. The victim's grandmother, Barbara DeRamus, says Fritch's mother wanted him out.

"He just seemed like a lowlife," DeRamus said. "I thought, 'What was Kirsten doing with this idiot?'"

Dobbs is being held on a $500,000 bond.
