Chicago police Officer Jason Van Dyke was convicted of second-degree murder and 16 counts of aggravated battery in the shooting death of 17-year-old Laquan McDonald, marking a stunning end to a racially tinged case that roiled Chicago when police dashboard camera video of the shooting was released three years ago by court order.

Judge Vincent Gaughan publicly confirmed that the jury deciding Jason Van Dyke's fate reached a verdict at 12:32 p.m. CDT Friday after less than eight hours of deliberation.

Before announcing the verdict, Gaughan warned the courtroom gallery against making any outbursts and promised to arrest anyone who disrespected the jury.

"I don't want anyone second-guessing them," he said.

Van Dyke appeared emotional and fatigued as the verdict was read, but his solemn expression did not break.

His wife, Tiffany, seated in the courtroom gallery, wept.

The slain teen's great-uncle, the Rev. Marvin Hunter, seated on the other side of the courtroom, also cried.

Spectators remained silent, though some could be seen praying.

Gaughan ordered Van Dyke's bail revoked at the prosecution's request.

"He now stands before this court a convicted felon," said Special Prosecutor Joseph McMahon, noting the officer faced a minimum of six years in prison.

Van Dyke was led out of court with his hands behind his back.
