Three of the seven children injured in a collision that killed a Waldorf man Thursday evening had been released from Children's Hospital by day's end Friday, said Craig Renner, spokesman for Charles County sheriff's office.

Richard Stephen Turner, 46, died instantly when he swerved his 1988 Plymouth Voyager into oncoming traffic about 6 p.m. in the 4000 block of Dr. Samuel Mudd Road, apparently to avoid hitting a dog, Renner said.

Turner's van struck a 1990 Ford Ranger head-on. The collision injured nine people, including the seven children. Turner, his wife Karen, and five children--at least one of them a friend of the family--were in the Voyager. Kevin Eugene Moyers, 33, of Waldorf, was driving the Ranger with two children as passengers.

Both drivers were pinned in their heavily damaged vehicles while the children, ages 3 to 12, were taken to the front porch of a nearby home where they waited for rescue workers.

Of the four children still hospitalized Friday night, two were in fair condition and two were listed in good condition. Authorities declined to identify the children or say which vehicle they were in when the accident occurred.

Karen Turner was treated at Children's Hospital and released after refusing medical attention at the scene. Moyers was treated at Washington Hospital Center and released.

Neither alcohol nor speed was a factor in the accident, Renner said. He credited the use of seat belts and safety seats by all the passengers in both vehicles with preventing more serious injuries.
