Divers searching the Colorado River in Arizona on Monday found the body of a woman who died after two boats slammed head-on into each other, with three other people still missing from the collision, officials said.
The Mohave County Sheriff's Office said she was located downstream of Topock, Arizona, near the California border.
"We are shocked and heartbroken to learn about the passing of one of our own in this weekend's tragic Colorado River boat crash", said Gary Herbst, Kaweah Delta's CEO.
Mortensen says Lewis was a California resident, but her hometown hasn't been determined.

A person with serious injuries was airlifted to University Medical Center in Las Vegas for treatment, officials said.
No one on the boats was wearing a life vest, Schuster said.
The search resumed Sunday, but authorities said the toll of missing had risen to four at that point.
The recreational boats crashed Saturday in Moabi Regional Park as darkness was falling on a rushing river crowded with holiday weekend boaters, making the rescue operation hard.
Both local authorities and other recreational boat owners searched the area Saturday, but the bodies of the two presumed dead have not yet been recovered.
Rescuers abandoned the search until Sunday morning because of the danger to divers working in the fast-flowing water after dark.
"We have four parties unaccounted for and presumed submerged", he said.
The crash happened Saturday on the Colorado River between Pirate Cove Resort & Marina in Needles, California and the Topock Marina in Topock, Arizona, north of Lake Havasu, officials said.
The cause of the crash is being investigated by Mohave County authorities, Sherwin said.
According to the LA Times, all 16 people were throw into the "fast-moving" river as the boats sank.
