A $50,000 reward was announced Tuesday for information that helps police find a motorist responsible for the hit-and-run death of a cyclist in South Los Angeles.

Frederick Frazier, 22, was struck by a white Porsche Cayenne SUV about 12:45 p.m. April 10 at Manchester and Normandie avenues and died at a hospital. The Cayenne was being driven east on Manchester when the collision occurred. The driver then headed south on Budlong Avenue before traveling west. The Porsche was last seen westbound near La Salle Avenue Elementary School, police said.

Frazier’s mother, Beverly Owens, made an emotional plea for help finding the person who killed her son.

“This is somebody’s boyfriend. This is somebody’s cousin,” she said. “… Somebody knows this dude and you are (harboring) and keeping your eye on a murderer. Whoever goes (and) fixes this dude’s car, you’re fixing the car to somebody that just killed somebody. He’s got blood on his car, he got blood on his hands.

“All you had to do is stop and stay with him. It was an accident. But now you’re a killer, you’re a murderer.”

Speaking to reporters gathered at the intersection where her son died, Owens added, “When the smoke clears, when the cameras leave, when everybody leaves, I’m at home with nobody with my baby gone. … You killed him. You killed him. Somebody knows who did it, and everybody needs money. The money is out there. Get it.”

Addressing the person who killed her son, she said, “With your morals, with your values, come forward. Turn yourself in. … God will see you and he knows. He knows. He knows.”

About 1 p.m. on the day following the fatal crash, a hit-and-run car struck and injured a man at a vigil that was being held for Frazier at the site where he was fatally injured.

“The gathering stopped the flow of traffic through the intersection,” police said. “The suspect attempted to drive her vehicle into the intersection, at which time, an argument started between the suspect and a female bicyclist.

“The argument quickly escalated into a brief physical altercation,” police said. “The suspect re-entered her vehicle and drove eastbound on Manchester Avenue, conducted a U-turn, then drove westbound at a high rate of speed.”

She hit a man who had been standing in the intersection, sending him flying into the air. The hobbled victim then hopped quickly to the side of the road. His injuries were not life-threatening, police said.

Video of the collision was soon making the rounds on social media.

Some of the dozens of bicyclists taking part in the vigil immediately began following the motorist, while some tried running after the driver on foot. The sedan, however, disappeared in the distance.

Due to the vigil, Los Angeles police were already on the scene when the pedestrian was struck.

Some rocks and bottles were thrown toward responding officers and a patrol vehicle, but no officers were injured and no arrests were made. Police swarmed and cleared the intersection, but not before a department SUV had its rear window smashed. The SUV’s tires had been flattened by the time it was towed from the scene.

The motorist involved in the non-fatal hit-and-run was driving a tan-colored Honda Accord that is now in police custody. She was described as black, 25-30 years old, about 5 feet tall and around 120 pounds. She was wearing a multi-colored head scarf, a white top and multi-colored tights. She also had a nose ring and a tattoo on the left side of her stomach area.

Anyone with information about either collision was urged to call (877) LAPD-247. Anonymous tips can be submitted through Crime Stoppers by calling (800) 222-TIPS.
