JACKSON, Miss. (WJTV) – A search for two Louisiana girls, who were allegedly abducted after their mother was killed, has ended tragically in Mississippi.

Jackson Police Chief Joseph Wade said the suspect at the center of an Amber Alert, Daniel Callihan, was captured in Jackson after a chase.

According to Wade, 4-year-old Erin Brunett was found dead in a wooded area. Her sister, 6-year-old Jalie Brunett, was found alive, and was taken to a Jackson hospital for treatment.

Wade said he didn’t believe Callihan is the girls’ father, but didn’t elaborate further.

The police chief said there was evidence that could be associated with human trafficking at the location where Callihan was found, including small animal cages. Wade said Jackson police have contacted human trafficking investigators to assess the scene.

Authorities said the Amber Alert was issued Thursday for the two girls, who were abducted after their mother was killed in Loranger, Louisiana.

Tangipahoa Parish Sheriff Daniel Edwards said 35-year-old Callie Brunett was found dead by her father on the floor of her bedroom inside her locked mobile home. She had been reported missing by her parents 24 hours earlier. They had last spoken to her Tuesday morning.
