Woman involved in fatal DUI collision that took two lives surrenders to police

CHP say collision that killed Pleasanton resident was a 'preventable tragedy'

A woman surrendered on Wednesday afternoon on two counts of vehicular manslaughter while intoxicated for a collision on Altamont Pass Road in unincorporated Alameda County near Livermore last October that killed two people, the California Highway Patrol said.

Courtney Lynne Peterson was driving her 2016 Ford F-250 on Altamont Pass Road east of Dyer Road at about 4:50 p.m. on Oct. 14 when, due to her intoxication, she allowed her vehicle to veer into oncoming traffic, resulting in a collision with a motorcycle carrying two people, according to CHP spokesman Tyler Hahn.

Mark Nida, 63, of Pleasanton, who was driving the motorcycle, and 64-year-old Kathleen Seifert, who was his passenger, were taken to Eden Medical Center in Castro Valley to be treated for their injuries but Nida was pronounced dead a short time later and Seifert died later that night, Hahn said.

Peterson was arrested after the collision but she was released while officers from the CHP's Dublin area and Golden Gate offices completed an extensive investigation, according to Hahn.

The investigation was presented to the Alameda County District Attorney's Office on March 7 and prosecutors charged her with two counts of vehicular manslaughter while intoxicated, Hahn said.

It's expected that Peterson, who turned herself in at the Santa Rita Jail in Dublin at 2:20 p.m. on Wednesday, will be arraigned later this week, according to Hahn.

Capt. Christopher Sherry, the commander of the CHP's Dublin area office, said in a statement, "This collision was a preventable tragedy. Two innocent lives were lost because someone chose to drive under the influence of alcohol."

Sherry said, "I am pleased that the suspect in this crime has been arrested. Nothing can bring back the lost lives, but I hope this arrest brings some comfort to the victim's family and friends."

He said, "More than one-third of all traffic-related deaths in California involve alcohol. As a community, we will not tolerate it."
