Charles Butler Jr., 23, was shot to death near his West Oakland home in December 2011. Butler had just completed a training program to become a merchant seaman.
Surveillance video shows Butler bumping another car as he parallel parked outside a store. Detectives believe someone from that car killed Butler a short time later.
Butler's father made a public plea recently for witnesses to come forward.
"We had a news release a month back, a month and a half back, where the father who is dying, requested that before he leaves this earth, that someone, please someone help him find the killers," Oakland Police Inspector Phong Tran said. "And a lot of people called, some just to express how sorry they are and others just to tell us what they know."
Police have arrested 21-year-old Giovonte Douglas. They say he was driving the car that approached Butler.
But police are still looking for the other suspect, 23-year-old Cartier Hunter, who police say actually pulled the trigger. If you have any information on his whereabouts, Oakland police ask you to call them.
As an organ donor Butler helped several recipients that holiday season.
"The fact that he gave his organs to someone else is the most wonderful Christmas gift ever. My brother is giving life to other people," Ann Butler said in December 2011.
His family told ABC7 News they are happy about Douglas' arrest. They're hoping Hunter will also soon be in custody.
