ORANGE — A 34-year-old man killed last week outside a Chili’s restaurant in Orange was a Philadelphia native turned activist who’d lost his son in 2014 after a fire destroyed nine homes and killed three other children as well.

Police arrested 29-year-old Trevor Lee Brockington Saturday, May 13, one day after he is accused of shooting Patrick Sanyeah to death in a parking lot.

Orange police investigators were still trying to determine the relationship between the two men and the motive for the shooting, Sgt. Phil McMullin said. It was the city’s first reported homicide this year.

Brockington, of Riverside, was charged Tuesday, May 16, with murder. He was being held in lieu of $1 million bail, according to jail records. His occupation is listed as a caretaker on the jail’s information log.

Sanyeah was well known in Southwest Philadelphia, according to the Philadelphia Inquirer, after his 4-year-old son died in the blaze.

He became the voice for the families who’d lost loved ones, often criticizing the city’s Fire Department and accusing it of being slow to respond to the deadly scene.

The Orange shooting occurred in a commercial and entertainment corridor filled with fans watching the Anaheim Ducks game in restaurants or at the nearby Honda Center.

It was unclear if the victim had moved to Southern California or was visiting.
