Concord Woman, 28, Accused In Fatal Walnut Creek DUI Crash

CONTRA COSTA COUNTY, CA — A 27-year-old Discovery Bay woman was killed and another person suffered major injuries when they were hit by a suspected DUI driver Saturday in Walnut Creek, police said.

Around 1:50 a.m. Saturday, an officer with the Walnut Creek Police Department heard a crash in the area of North Main Street and Pine Street and found a pickup truck had collided with two pedestrians who were walking on the east sidewalk of N. Main Street near Pine Street, Walnut Creek police Lt. Holley Connors said in a news release.

It is alleged that the driver, 28-year-old Briana Day of Concord, struck the pedestrians as they were walking on the east sidewalk of N. Main Street near Pine Street.

She also collided with a cement pillar, Connors said.

One victim was pronounced dead at the scene. The other victim was rushed to a hospital.

The Conta Costa County Sheriff-Coroner's Office identified the person killed as Maricarmen Leon, 27, of Discovery Bay.

By Tuesday morning, more than $15,000 has been donated toward funeral costs for Leon, whose loved ones described as "an amazing daughter, sister, cousin, and friend" who was "constantly smiling and laughing."

"She was following her dreams at Kaiser as a phlebotomist, where she stood out as a hard worker who always gave her all," according to a GoFundMe page. "We hope to raise money and support the Leon family during this difficult time by helping the family cover funeral costs and ease the pain of losing such a beloved family member. Please keep the family in your prayers."

Day was arrested on suspicion of driving under the influence of alcohol causing injury, as well as gross vehicular manslaughter while intoxicated. She was booked into the Contra Costa County jail in Martinez and her bail was set at $300,000, police said.

The Walnut Creek Police Department planned to present the case to the District Attorney's Office this week for review, and asked anyone with information related to the investigation to call Walnut Creek PD Dispatch at 925-935-6400.
