Biker killed in two separate collisions in Antioch

ANTIOCH, California. – A bicyclist and a motorcyclist were killed in two fatal crashes in Antioch on Saturday, police said. At least one of the drivers was arrested.

The first accident occurred at the corner of Lone Tree Way and Sagebrush Drive. Police responded to the scene a few minutes after midnight when they saw the victim riding a bicycle.

Despite life-saving measures, the cyclist, who was only a 29-year-old woman, died at the scene of the accident. The driver, who was only a 38-year-old man from Antioch, remained at the scene of the accident.

He was later arrested on suspicion of driving under the influence of alcohol, which resulted in serious bodily harm or death, police said.

Several hours later, a 32-year-old motorcyclist collided with an SUV outside the Bev Box at 907 W 10th Street around 7:40 p.m. The biker was a Brentwood resident, officials said.

He was taken to a local hospital where he was pronounced dead.

Police are still investigating, but witness statements and videos suggest speed played a role in the accident.

The driver remained at the scene of the accident; at this time, no arrests had been made in connection with the accident.
