Two cars were speeding near Lopes Road and Canyon Hills Drive Sunday night when one of them hit a car turning onto the road.
Police are still looking for the driver of the black, late-model Toyota Tundra; they believe the driver could offer valuable details about what happened in the seconds before a high-speed crash took the life of an innocent father of three.
"Don't take anything for granted, because it could be the last time you see them," said the victim's girlfriend Katie Reynolds.
Ron Brackett was struck and killed on Sunday less than 10 minutes from the home he shared with his girlfriend and their 2-month-old son.
"I just want them to know Ron was a really good person. He was a good father and a good boyfriend and he didn't deserve to go so early in life. He had a long life ahead of him," said Reynolds.
The 31-year-old died at the scene of the crash just west of Interstate 680. Police say the accident started when the drivers of an Infiniti coupe and the Toyota Tundra started, heading south on Lopes Road, at high rates of speed. Brackett was making a left turn from Canyon Hills Drive to Lopes - when the speeding cars smashed directly into his Mazda.
Cameras captured the chaotic aftermath and evidence collected by police at the scene have fueled investigators with more questions for the driver of the Toyota, because that driver did not stop after the crash and has not come forward.
Monday, police were back on the scene speaking with family members and looking for witnesses.
"We're still trying to identify who it may be so we can talk to him about what took place here, what his involvement was, how he was tied in with the Infiniti when they were traveling southbound," said Sgt. Matt Bloesch of the Fairfield Police Department.
Police are trying to determine if road rage or drag racing were factors.
"We need to talk to him to help put more of these pieces of this collision together," said Bloesch.
The driver of the Infinti was taken to the hospital and remains in critical condition. Those who knew and those who love Brackett are struggling to understand it all, while police hunt for the driver of the Toyota.
