Clearwater, Florida (CNN) Michael Drejka, who fatally shot an unarmed man , Markeis McGlockton, last summer in Florida during a dispute over a handicapped-accessible parking spot, was found guilty of manslaughter Friday night.

The judge set the sentencing date for October 10. Drejka faces up to 30 years in prison.

Drejka, who didn't take the witness stand, tried unsuccessfully to use Florida's "stand your ground' law as a defense for justifiable homicide. The case renewed a nationwide debate on the controversial law.

Jury deliberations lasted about six hours, with a brief pause around 9:30 p.m. when jurors sought clarification on the instructions for deciding guilt or innocence.

The judge sent the jury back to the deliberations room after rereading the instructions to them, and about a half hour later the jury announcedit had a decision.

McGlockton's family wept at the verdict. Drejka at first had no reaction but then started wiping his face as the judge spoke to the jury.

Defense attorneys rested their case earlier in the day after two expert witnesses testified about the defendant's state of mind and his actions at the time of the controversial shooting.

The court later instructed jurors on the law before closing arguments in which prosecutors portayed Drejka as an armed vigilante and defense attorneys described him as a victim who feared for his life.

Prosecutor Fred Schaub quietly told McGlockton's family before the closings, "I bet you never thought this day would come."

In closing for the state, Scott Rosenwasser urged jurors to ask themselves whether the defendant was justified in shooting an unarmed man
