According to SPO2 Franco Francia of the RDSU, Evangelista was still on duty at Camp Bagong Diwa in Taguig when he decided to go home early yesterday to bring his salary to his wife.
"Initial information reaching us revealed that the wife wanted to go with Evangelista back to Camp Bagong Diwa, which he refused to do," Francia said.

The cops mother-in-law tried to pacify the couple and joined her daughter inside the vehicle.
This enraged the cop even more. He alighted from the vehicle, pulled out his service pistol and fired at the back seat, where his wife and mother-in-law were seated.
