TEXAS CITY, Texas – The Baytown Police Department confirmed they have found the body of missing 16-year-old Kirsten Fritch on Thursday.

Equusearch had just started searching when a volunteer on an ATV came across the body. It was found in a wooded area near a building just north of the Shenanigans bar located on 34th Street.

Investigators arrested Fritch's boyfriend, 21-year-old Jesse Dobbs, outside of the bar early Wednesday morning.

Authorities issued an Amber Alert for Fritch after her mother and younger sister were found dead in their Baytown home. Police say Dobbs is a person of interest in the case. The Amber Alert was discontinued Thursday afternoon.

"We need her home," said Fritch's grandmother, Barbara DeRamus. "This is a mother and grandmother's worst nightmare."

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

"He just seemed like a lowlife," she said. "I thought what was Kirsten doing with this idiot."

Tuesday morning, police found Fritch's younger sister, Breanna Pavlicek, 13, and their mom, Cynthia Morris, 37, dead with gunshot wounds in the family's Baytown house.

"I believe he murdered my daughter and my innocent 13-year-old granddaughter," said DeRamus. "I hope he rots in hell."

According to court documents from Polk County, Dobbs was arrested and charged after striking a family member earlier this year.

Police have not charged Dobbs with the murders. He is currently being held in the Galveston County jail on charges of resisting arrest.
