The search for a missing Texas teen — whose family was found slain in their home earlier this week — came to an end Thursday with the discovery of her body, PEOPLE confirms.
An AMBER Alert was issued for 16-year-old Kirsten Fritch after police discovered both her mother and sister dead in their home in Harris County, Texas, on Tuesday morning, authorities said in a statement.
Police said Cynthia Morris, 37, and her 13-year-old daughter, Breanna Pavilicek, had been shot.
On Thursday, Kirsten’s body was found behind a bar in a wooded area in Galveston County, Texas, according to Baytown, Texas, police Lt. Steve Dorris. Her body was discovered by a volunteer on an ATV helping comb the area in a community search.
He was charged with resisting an arrest and is a person of interest in all three killings, Dorris says.

There is no known motive, Dorris tells PEOPLE. Dobbs refused to speak to police and asked for an attorney.
Kirsten’s grandmother Barbara DeRamus told KHOU that Dobbs and Kirsten met online.
DeRamus said he moved into the family’s Baytown home a few weeks ago — against her mother’s disapproval.
“He just seemed like a low-life,” DeRamus told the station. “I thought, ‘What was Kristen doing with this idiot?’ ” (DeRamus could not immediately be reached by PEOPLE.)
Police have not yet charged Dobbs with murder in the three killings, Dorris says.
It was not immediately clear if he has entered a plea to his resisting arrest charge or actually retained an attorney after requesting one. He remains in custody.
