Crash victim still critical but improving

A 51-year-old Brentwood motorcyclist remains in the hospital in critical condition and a 21-year-old Clayton woman faces criminal DUI charges after a head-on collision on Clayton Road on June 27.

Mark Tomaszewski was headed home after work about 5:40. He was traveling in the southbound lane when a northbound Toyota Corolla driven by Jessica Mercurio, 21, jumped the median into oncoming traffic and hit Tomaszewski head-on. She continued on after the collision, finally hitting a pole in the center divide in front of the Clayton City Hall.

She failed the field sobriety test at the scene and was arrested for DUI. Witnesses at the scene say they heard her tell officers she was texting when she lost control.

According to Clayton Police Chief Chris Thorsen, criminal charges are pending final toxicology reports.

Tomaszewski sustained life threatening injuries and remains in critical condition at John Muir Medical Center.

According to his brother, Tomaszewski is “improving some every day.” He is responsive to voice commands and recognizes family during the brief times he is awake.

Tomaszewski is an operating room technician at the Sequoia Surgical Center in Walnut Creek. “Mark is going to need ongoing care and support for a long time,” said Sequoia administrator, Tina Hadaway. His co-workers have donated their unused time off to him and a website has been set up to raise funds to help offset mounting medical bills.
