The shootings happened around 3 p.m. while a service was ending at the New Destiny Christian Center.

Police said two vehicles ended up in the church parking lot after some sort of argument between the drivers. Police said one vehicle was chasing the other. The man who was being chased got out of his vehicle and entered the church and told people to take cover. A woman came out of the church to see what was happening in the parking lot and got shot.

Police said an off-duty officer was at a service and went outside and shot the man who shot the woman.
