Officials are looking for a big rig driver who fled after fatally striking a bicyclist in Boyle Heights on Friday night.
Jaime Ramirez, 24, of Maywood, died in the 9:30 p.m. collision at Lorena and 8th streets, the Los Angeles Police Department said in a written statement.
He was riding south along Lorena Street in between two traffic lanes just prior to the crash, officials said.
"As the bicyclist approached 8th Street, he was unable to maintain control of bicycle, fell onto the street and ended up under a 40-foot box trailer that was traveling on the No. 2 lane," according to the police statement. "The bicyclist was struck by the trailer's tires."
The truck driver did not stop to help the bicyclist, police said. Paramedics pronounced Ramirez dead at the scene.
A witness chased after the truck and managed to take a picture of the trailer's license plate, officials said. The crash was also captured by a nearby surveillance camera.
Police described the truck and trailer as all-white, including white rims, with a sleeper cab and California license plate 4MY4587. There were no obvious company logos visible, and the specific make and model of the truck were unclear.
Investigators were not able to contact the registered owner, officials said.
Los Angeles offers a standing $50,000 reward for information that leads to the capture and conviction of drivers responsible for fatal hit-and-run collisions.
The victim, an avid cyclist who was out for a ride on his new bicycle when he was struck, left behind a 6-year-old son, his sister Rosa Ramirez told KTLA.
Jaime Ramirez's family urged the hit-and-run driver to come forward.
