Searchers found the body of a missing Houston-area 16-year-old Thursday afternoon not far from the bar where her boyfriend was arrested days earlier. 

The Baytown Police Department said a volunteer on an ATV discovered the remains of Kirsten Fritch in a wooded area just north of the Shenanigan's bar in Texas City.

Fritch's boyfriend, 21-year-old Jesse Dobbs, had been arrested by police Tuesday night after he walked into the bar barefoot and requested a glass of water. 

Authorities had issued an Amber Alert for Fritch after her mother, 37-year-old Cynthia Morris, and Morris' 13-year-old daughter Breanna Pavlicek were found shot to death in their Baytown home Monday morning. 

Dobbs was initially charged with resisting arrest. However, Baytown police spokesman Lt. Steven Dorris said murder charges would likely be brought against him in Fritch's death.

Authorities are investigating the death of the teen's two relatives, in which Dobbs is described as a "person of interest."

It was not immediately clear how Fritch died, though Dobbs said investigators would be "looking for a gun."

Fritch's grandmother told KHOU that her granddaughter and Dobbs started dating after they met online. 

He just seemed like a lowlife," Barbara DeRamus told the station. "I thought what was Kirsten doing with this idiot."

KTRK reported that Dobbs has two children from a previous relationship. He was charged earlier this year with domestic violence against the children's mother, who said he was known to use methamphetamine.
