SAN JOAQUIN COUNTY -- A boat crash on the San Joaquin Delta left one woman dead and at least five people injured.
Two boats collided Saturday night around 7:15 near Ski Beach in San Joaquin County -- a popular stopping point for boaters on the Delta.
San Joaquin County Sheriff's Office spokeswoman Andrea Lopez said investigators initially believed the crash was a hit-and-run but later reported that not was the case.
“We’ve learned that since then, the other boat fled to Contra Costa County. They’ve maintained contact with our office and they were seeking medical attention for passengers on that boat,” Lopez told FOX40.
Deputies do not yet know how many people were injured on that boat and later hospitalized in Contra Costa County but five other people were being treated in San Joaquin County hospitals.
The San Joaquin County Sheriff’s Office identified the woman who was killed as 24-year-old Kelly Blake from Discovery Bay.
The victim's close friends told FOX40 Blake was a bright and lighthearted person who had a lot of friends and made new friends everywhere she went. They said she was intelligent, had a wild and happy spirit, and lived her life to the fullest.
Those closest to her said Blake will be missed and loved forever.
The U.S. Coast Guard assisted the San Joaquin County Sheriff's boating unit to retrieve the boat Sunday afternoon.
Deputies say the cause of the crash is still under investigation.
“We don’t know if speed, alcohol or lighting was a factor,” Lopez said. "We’re looking into all of it."
Deputies have not arrested anyone involved in the crash and say criminal charges can still be pursued.
People were back out at Ski Beach Sunday and with a couple of weekends left of summer, the sheriff's office was warning everyone on the water to follow basic boating rules to stay safe.
“Please ride with a sober driver, wear a life jacket and be cautious of the areas around you and the people around you,” Lopez said. “You have jet skis in the water, you have water skiers in the water and swimmers in the water. So we all need to be cautious of everybody and look out for one another.”
