A man died after a dirt bike crash during a racing event in Solano County on Sunday, officials said. 

On Monday, the Solano County coroner identified the driver as Aaron Bissell, 52, of Reno. 

The Vacaville Fire Protection District (VFPD) responded to Argyll Park on Cook Lane in Dixon around 10 a.m. for reports of a motorcycle crash. The park was hosting a series of competitions that day put on by the "Over the Hill Gang" or OTHG, a veteran motocross club with chapters in California and Nevada. 

Ken Gourley, president of the OTHG Reno chapter, says Bissell served as the group's vice president and was not only an 'expert' driver, but a core member of the group who will be deeply missed. 

"He knew everything, how to do everything behind the scenes. He was a man of impeccable integrity. Honest, hardworking, he contributed his own personal time and took pride in what we are able to do as a club. I can't say enough about his character and the person he is," Gourley said. "I am heartbroken for his family, wife and daughters. They have to suffer through this loss. Our club is reaching out to them to be supportive going forward. It's very much a community of racers and we will stick together through this."

It's believed Bissell went off the track at a sharp turn. Reports that he suffered a medical emergency prior to the accident have not been confirmed. 

Medics with a standby ambulance during the event located him unconscious in a pond adjacent to the dirt track. 

The VFPD thanked the on-site medical team at the track and a group of bystanders that included off-duty trauma nurses who rushed in to help Bissell, removing him from the pond and engaging in CPR until first responders arrived. 

"We give them props for just being out there, being our first hands. We always want to push out there. We love that bystanders jump in to help. We also encourage if you don't know CPR, learn it. You never know when you could use it," said Chief Phil Jones of VFPD. 

Despite the lifesaving efforts, Bissell was pronounced dead at the scene. 

Jones was grateful the bystanders stepped in, adding that the closest emergency responder crew was 15 minutes away.

"This is rare. We do get calls out there. It's a motorcycle track. People fall. We get broken bones here and there, but we don't get anything at a fatality level. I haven't seen a fatality out there in a long time," said Jones.   

The Argyll Park track is located off Highway 113 and is about 15 miles southeast of Vacaville. 

Bissell is remembered as a fearless rider, a beloved husband to his wife Rachel and a devoted father.
