HIGHLAND PARK, Mich. -

The last time anyone saw Highland Park teenager Jonathon Thornton was on April 8 when he left his father's home on 2nd Avenue.

The 16-year-old was preparing to enter Highland Park High School. His mother, Stacey Jones, said she is fearful for her son.

"This is my oldest first-born child. We have a very strong bond with each other," Jones said.

Stacey Jones said she believes her son is with someone, but she is concerned because Jonathon is so young.

"I believe he left with someone who is older than he is. He doesn't know much about life. He hasn't been out there. He doesn't know what goes on. It's dangerous and I feel like he's in danger. I just want anybody that knows anything, speak up," Jones said.

John Broad of Crime Stoppers of Michigan said his family knows what Jonathon was wearing when he was last seek.

"He was wearing stud earrings in both ears, a black Detroit jacket with white trim and Air Force One shoes," Broad said.
