TEXAS CITY, Texas --Search teams will be back out in Texas City this morning looking for signs of a missing teen near the bar where her boyfriend was arrested.
Kirsten Fritch is just 16 years old and hasn't been seen since her mother and sister were found shot to death in their Baytown home.
ABC13 has learned from police that Kirsten's mother and her sister were killed between 12 a.m. - 10:30 a.m. on Tuesday when Kirsten's grandmother called police. Breanna Pavlicek was just 13 years old. Mom Cynthia Morris was 37.
Police are not sure whether Kirsten was in school on Monday but they say she did "communicate with friends" that day. Kirsten's aunt told Eyewitness News this morning that Kirsten was "getting into runaway mode" and skipped class a lot.

Investigators believe he knows something about the murders and Fritch's disappearance, but they say he isn't cooperating.
Dobbs has only been charged at this time with resisting arrest.
Bar owner Sarah Skaggs claims Dobbs told police "I had to do it or else they were going to kill my son," before he was taken away.

Police have not discussed any possible motives in the case.
Eyewitness News uncovered court records from Polk County showing Dobbs plead guilty in May to assaulting his ex-girlfriend, who is also the mother of his two young children.
She tells us Dobbs has a drug habit, and described their three-year relationship as "abusive."
