It was nigth time at 8:37 pm in LA. Ervin, or officer Ervin Onishi, was walking through a dark alleyway. Someone said that there was some suspicious activities and is worried what's in there. That's why his there. If only if he have known, his 6 year old son, Liam, was following him and did it by sneaking into his police car. Liam probably left the car to explore as Ervin was just doing his job, holding a flashlight.
