LAGUNA BEACH — A 16-year-old boy who allegedly stabbed a former classmate and injured two others after fighting on Facebook was arraigned Monday on three felony counts of aggravated assault.

Michael Jason Wilson will be tried as an adult, and faces a maximum sentence of 15 years in state prison if convicted, according to the Orange County District Attorney’s office.

Authorities say Wilson and a former high school classmate, identified only as a 17-year-old named Julian C., had a series of arguments on Facebook, and also exchanged text messages and e-mails. Authorities did not disclose the nature of the messages.

Wilson apparently agreed to have Julian C. come to his home on March 11.

Julian C. drove to Wilson’s house with two 16-year-olds, identified as Nicholas L. and Sam S., and a fourth friend, prosecutors said.

Wilson allegedly walked out of his house with a 12-inch knife and stabbed Julian C. in the stomach.

The three other friends got out of the car to help Julian C., and two of them suffered cuts to their arms and hands, according to prosecutors.

The four boys drove away from Wilson’s house, and flagged down a police officer.

Julian C. and Nicholas L. required surgery for their wounds. Sam S. received stitches and was released.

All were said to be doing fine.

Wilson is currently free on $65,000 bail.
