SAN JOAQUIN COUNTY (CBS13) — A tight-knit San Joaquin community in mourning tonight after one of their own, 24-year-old Kelly Blake was killed in a head-on boat crash on the delta.

The boat dock at the popular hot spot Union Point Bar & Grill was filled with saddened boaters who were mourning the sudden loss of a friend

We just wanted to pay respects to our friend who passed yesterday. Just left some flowers there…nothing really more we could do,“ said Misha Usunov, who drove out to Ski Beach where Blake was killed.

Blake died Saturday evening when the boat she was in collided head-on with another boat.

“We’re out here a lot and the boating family’s very close and she was part of it,” Usunov said.

Usunov said Blake had an addictive personality.

“You meet her, you have an instant bond with her,” he said.

The San Joaquin County Sheriff’s Office said Blake was killed and five others were injured near Ski Beach around 7:15 p.m. Saturday when the boats crashed into each other as they were rounding a curve.

Christine Alfaro, who regularly boats on the Delta, said the crash had to be a human error because the boat was on the wrong side of the water. Wreckage of the boat was towed to Discovery Bay. Investigators are trying to determine whether speed or alcohol was a factor, and who was at fault.

Eric Stark from Stockton says he witnessed the crash.

“Two boats were coming around the corner at the same time…hit head-on. One boat went over the other,“ he said.

Many locals said that while the delta is beautiful, it can be very dangerous when alcohol is consumed.

“I see people casually drinking and driving, which is weird because people don’t just casually drink and drive a car but they casually drink one to two beers, three beers and drive a boat,“ said Usunov.

The driver of the other boat involved in the crash is cooperating with investigators. Stark said he would like to see more regulations on the water.

“Out here [there are] not that many restrictions and you can kind of do what you want to do, and when that happens, things like this happen,” said Stark.

The sheriff’s office is asking for any witnesses to come forward.
