Authorities this week confirmed the identity of a Livermore man who died in a solo-vehicle rollover crash on East Airway Boulevard just over a week ago.

The decedent was 39-year-old Nathan Quimby, according to the Alameda County Coroner's Bureau.

Quimby had lived in Livermore for more than 10 years before his sudden death on Jan. 21, family members said on a GoFundMe page created in his honor. 

"Those who knew Nathan know what a genuine person he was, he loved everyone, cared about how their day was going, and he always had a smile on his face," the organizers said. 

"When someone speaks of Nathan, it's impossible for them to not mention his laugh, and how happy he always seemed to be. Nathan loved fishing, biking, road trips and getting his hands dirty, whether it was at work or through one of his many hobbies. What he loved most though was his family and friends," they said. 

The GoFundMe drive had collected more than $2,300 in contributions, as of Wednesday afternoon, toward its $5,000 goal to help his family with funeral costs and other expenses resulting from his unexpected death.

According to Livermore police, the deadly crash occurred just before 2 p.m. on Jan. 21 when the driver of a Toyota Yaris -- later identified as Quimby -- lost control of his car and it overturned several times on East Airway Boulevard near the Rutan Drive intersection. 

Officers arrived to find Quimby seriously injured, and paramedics later pronounced him dead at the scene. Police said the circumstances of the solo crash remain under investigation, including whether speed or intoxication were contributing factors.
