An Indiana teen who went missing earlier this week is now in police custody, charged with her own mother’s murder.

Chastinea Reeves, 15, is being held at a juvenile center on suspicion of murder, according to the Times of Northwest Indiana.

Reeves was the subject of an AMBER Alert earlier this week, after she vanished right around the time her mother, Jamie Garnett, was found dead in their Gary, Indiana, home. At the time, police said only that her mother was a victim of a violent crime, and it was unclear how the incidents were connected. Now it appears Chastinea may have killed her.

It is unclear when Reeves became a suspect in her mother’s death, but she was apprehended on Thursday afternoon.

Garnett, 34, reportedly died of multiple stab wounds.

Reeves reportedly ran with a younger sibling to an aunt’s house following her mother’s stabbing. Her aunt said she was “hysterical.”

“Two children came to my door a little after 2 a.m. and they said someone had come in, somebody had did something to their mom,” her aunt told ABC7. “She run out the back door when the police come.”

But now it appears that story may have been a lie. Police have not yet provided further specifics or a motive.

According to the New York Post, prosecutors are seeking to charge Reeves as an adult.
