ORLANDO, Fla. -

The jury found Timothy Davis Sr., a former Orlando police officer, not guilty on Thursday of shooting and killing his 21-year-old son in Apopka after five hours of deliberations.

Timothy Davis Sr. was acquitted of second-degree murder in the shooting death of 21-year-old Timothy Davis Jr. during an argument over custody of Davis Jr.'s son on October 1, 2011.

About an hour after deliberating, the jury on Thursday requested to watch video of the shooting that was shown during the trial.  After viewing the video, the jury resumed deliberations.

The jury later asked for definitions of "gross" and "flagrant," which are two words in the jury instructions with one of the lesser charges. Jurors also asked to listen to a taped police interview.

Earlier in the day during the state's closing arguments, prosecutors emphasized Davis Sr.'s statement to police on the night of the shooting, in which he said, "I didn't mean to kill him, I wasn't trying to kill him. I just lost it."

Prosecutors say the statement proves Davis Sr. shot his son out of anger, not out of fear.
