ORLANDO, Fla. -

The jury has been seated on Monday in the trial for Timothy Davis Sr., a former Orlando police officer accused of shooting and killing his 21-year-old son in Apopka more than a year ago.

Timothy Davis Sr. was charged with second-degree murder in the shooting death of Timothy Davis Jr. during an argument on October 1, 2011.

Surveillance video shows Davis walking to his car, grabbing a gun and then firing a shot at his son.

Prosecutors say Davis killed his son when an argument between the two men got out of control.

Davis, though, says that he shot his son in self-defense, telling police investigators that one bullet was meant as a warning shot and that the second shot was an accident.

The son of Davis Jr. was 3 years old at the time of the shooting.

Davis was in court on Monday, reading his Bible during the jury selection. The only disruption from Davis was a phone call.

The jury selection took 7 hours to complete.

Prosecutors have 18 witnesses they will call and the trial is expected to last one week.

If convicted, Davis faces life in prison.
