Sheriff's deputies said the teen (pictured, left) had been arguing with his mother, Diane Michele, a 50-year-old psychologist, over the past few days.

At some point Sunday night or Monday morning, Michele was stabbed to death, sheriff's deputies said. Michele's body was found by her mother on Monday morning in her home in the 3000 block of Palm Aire Drive in Rochester Hills, according to sheriff's deputies.

"There appears to be multiple stab wounds and we did find a knife or two in the area," said Oakland County Sheriff Michael J. Bouchard.

Dankovich, who does not have a license, was believed to have fled the home in his mother's white 1999 Chevrolet Astro van (pictured, right) with a personalized plate that says LOVE4U, according to sheriff's deputies.

"We're checking every place we think. We'd like the public's help if they see this guy," said Bouchard.

Sheriff's deputies were concerned that the teen may be a threat to himself or to others, the station reported.

The 15-year-old was taken into custody without incident.

There was no word on what charges the teen may face.
