Remain Missing After Boat Crash in Colorado River Along California-Arizona Border

Colorado River boat crash

Divers returned to the roaring Colorado River Monday in search of four people missing and presumed dead after a grisly, head-on boat collision along the California-Arizona border that injured 13 other people.

The victim was as identified as Christi Lewis, 51, from California, the Mohave County Sheriff's Office of Arizona said in a Facebook post.

All those aboard both boats were thrown into the water and both boats sank, the sheriff's department said in its statement, adding that some people were rescued from the water by passing boaters.

Searching for the missing men are rescue boats, divers and helicopters from the Mohave County Sheriff's Office and the San Bernardino Sheriff's Office of California. A person with serious injuries was airlifted to University Medical Center in Las Vegas for treatment, officials said. Nine others were taken to local hospitals by ambulance.

Sheriff's Office spokeswoman Anita Mortensen said Monday that investigators had yet to determine what role speed might have played in the accident.

Eric Sherwin, spokesman for the San Bernardino County Fire District, says the vessels collided head-on Saturday evening. Officials deemed it too risky to allow divers in the water after dark but planned to resume their search Sunday morning.

The fire department initially said two people were missing and "presumed submerged".

Search teams scour the Colorado River.

"We had victims of this collision that were located 3 to 5 miles downstream from the original point of impact", said Sherwin.

Numerous boats were in the water at the park on Saturday, a popular recreational area where the river's depth ranges from shallow to 30 feet.

Sonar images of the sunken boat indicated that neither of the missing people were on board, he said.

Lewis was missing since about 8 p.m. Saturday, when a northbound Hallet boat carrying 10 people collided with a southbound Sleekcraft, which carried six people, according to officials.

The cause of the crash is being investigated by Mohave County authorities, Sherwin said.
