On Crowded Colo. River, 4 Missing After Boats Collide

Four people are missing after two boats crashed on the Colorado River, reports the AP, ejecting more than a dozen people who were on board. The Mohave County Sheriff's Office said Sunday that a boat carrying 10 people and another vessel with six people on board collided head-on after dark Saturday night on the river that borders California and Arizona. Authorities say both boats sank, throwing everyone aboard into the water; passing boaters helped pull victims from the water, though the search had to be called off at 9pm local time. It resumed early Monday.

One person was found in critical condition and flown to a hospital in Las Vegas. Nine others were taken to local hospitals by ambulance. Authorities are searching for four people who remain missing. Anita Mortensen, a spokeswoman for the Mohave County Sheriff's Office, says none of the boaters were wearing life vests when the collision occurred. The crash happened in Moabi Regional Park, a popular water recreation area along the border about 290 miles east of Los Angeles. The area was packed with people celebrating ahead of Labor Day, notes ABC News.
