The man accused in that slaying, Christopher Fields, 33, of Newark, N.J., was charged last night with murder, weapons violations and related offenses, police said.
A police source said that Fields is a member of the Wheels of Soul motorcycle club, and that his "colors" - clothing identifying him as a member of the club - were recovered in a trash can near the scene next to a semiautomatic pistol allegedly used in the shooting.
The source said the fatal shooting was motivated by road rage. Fields apparently thought that Riley had cut him off in his Buick Century while the biker was driving on Roosevelt Boulevard with his fellow club members, the source said.
At some point, the source said, Fields drove up to the Buick and blasted into its driver's door.
When police arrived, they found several bikers surrounding the "bullet-riddled" car, as well as more than seven spent shell casings nearby, the source said.
Riley and his girlfriend, riding in the car's passenger seat, had both been hit multiple times, and police rushed them to Temple University Hospital. Riley's girlfriend, whose identity was withheld by police, was in stable condition last night.
Meanwhile, officers saw Fields fleeing the scene, and tailed him for a few blocks before apprehending him, police said.
"When I heard about it, I couldn't believe it was real," a grieving Johnson said last night. "You're not supposed to kill someone over something like that."
Riley leaves three children: a 17-year-old son and two daughters, ages 10 and 6. Johnson said that when his cousin wasn't working for a Norristown-based sanitation company, he devoted all his attention to his kids.
"He was a family man. He was just a fun person to be around," he said of Riley.
A viewing for Riley will be held at 10 a.m. Thursday at the Khadijah Alderman Funeral Home, on Hunting Park Avenue near Arch Street in Nicetown, his family said. It will be followed by a janazah traditional Muslim funeral prayer at 11 a.m.
