-Four people are missing after two boats crashed and sunk on the Colorado River, ejecting more than a dozen people who were on board, authorities said Sunday.
Two people were reported missing and 13 people were injured after a head-on boat crash in the Colorado River near the California-Arizona border Saturday.
Officials said two recreational boats, one carrying 10 people and one with six, collided around 8 p.m. Saturday near Moabi Regional Park.
Mortensen says Lewis was a California resident, but her hometown hasn't been determined. One boater remains missing.
Ten people were injured in the crash. Nine others were hospitalized with less serious injuries.
Sheriff Doug Schuster of the Mohave County Sheriff's Office said that none of the 16 boaters involved in the crash were wearing life vests, which are not required by law.
The crash happened in Moabi Regional Park, a popular water recreation area along the border about 290 miles (467 kilometers) east of Los Angeles. The search for two people "presumed submerged" was halted overnight Saturday, the San Bernardino County Fire District said in a statement. Divers have been sent into the river, which can run as deep as 30 feet (9 meters).
Helicopters have been deployed as part of the search, and authorities have scoured the shoreline.
More than 60 crew members from Arizona and California continued to search on boats at sunrise Monday, tracking their progress with a computer program that mapped the riverbed, according to USA Today.
Rescuers abandoned the search until Sunday morning because of the danger to divers working in the fast-flowing water after dark.
Other passengers are believed to have jumped into the water and been carried down river. The Mohave County Sheriff's Office said it will continue to patrol the Colorado River until all passengers are accounted for.
