A 21-year-old motorist was killed during a crash involving another vehicle and a Metro train in Long Beach, authorities said today.

Officers were dispatched at about 11:55 p.m. Friday to the area of 12th Street and Long Beach Boulevard, according to the Long Beach Police Department.

Police said the deceased woman, a 21-year-old from Compton, was speeding southbound on Long Beach Boulevard in a 2014 Infinity Q50S — without headlights on — when a 2019 Honda Accord, driven by a 29-year-old man, made a southbound turn from Anaheim Street to Long Beach Boulevard in front of the Infinity.

The Accord swerved out of the way to avoid being rear-ended and struck a guardrail, while the Infinity swerved, lost control and struck the Metro train.

Paramedics rushed the woman to a hospital, where she later died from her injuries.

The driver of the Accord stayed at the scene and cooperated with police, authorities said.

“Speed and impaired driving are being investigated as potential factors in this collision regarding the driver of the Infinity,” according to a police statement.

No injuries were reported aboard the train.
