MIAMI -

Opening statements began Monday in the trial of Andrew James Rolle, 26, who’s accused of fatally shooting a Miami detective while off duty.

Rolle is claiming he shot the officer in self-defense, but prosecutors say he should be convicted of first-degree murder.

The case dates back to 2008, when police say Rolle shot and killed James Walker, who worked in the domestic battery unit for seven years.

Rolle’s attorney claims the shooting was an act of self-defense and tried to get immunity under Florida’s “Stand Your Ground” law. The attorney argued Monday that his client fired his weapon after Walker pulled out his gun.

Prosecutors were quick to point out that Rolle had just shot another man, and was trying to get away using the unmarked police car that Walker was sitting in at the time.

The first witness called Monday was the officer who responded to shots fired. He confirmed that it was Rolle who he saw inside Walker’s car where he found the detective shot to death.
