Arizona authorities say they have found the body of a woman who was among four people missing after two boats crashed on the Colorado River. Mohave County Sheriff’s Office spokeswoman Anita Mortensen says 51-year-old Christi Lewis was found Monday in a section of the river that borders California and Arizona. Authorities say a boat carrying 10 people and another vessel with six people on board collided head-on Saturday night, ejecting more than a dozen people. Both boats sank and passing boaters pulled people from the water. None of the people in the two boats were wearing life vests. The search is continuing for the three other missing people.
