An Air Force sergeant driving his teen-age daughter and two of her girl friends back from a high school event in La Plata, Md., died Saturday night in a head-on collision that killed two other Charles County residents and severely injured four others, including the three girls, Maryland state police reported.

The accident occurred shortly before 11 p.m. at the intersection of Rte. 6 and Prince Charles Drive, about 2 1/2 miles east of La Plata, police said.

Pentagon-based Sgt. Donald Arthur Brown, 37, of 526 University Dr., Waldorf, was pronounced dead on arrival at Physicians' Memorial Hospital in La Plata. He had been driving his 14-year-old daughter, Kristy Leigh, and two of her friends, Shelly Jean Sellner, 12, of 528 University Dr., and Christina Jean Simpson, 14, of 525 University Dr., back from a social event at La Plata High School when their car collided with an auto driven by Samuel David Wolf, 20, of Sparrow Court, Bel Alton.

Police said Brown's car was going west on Rte. 6 and Wolf's car going east when Wolf's auto apparently went out of control near the Prince Charles Drive intersection, crossed the double median line and struck Brown's car head-on.

Wolf's passengers, Tracy Rene Fertig, 18, of Rte. 1, Newburg, and Raymond Scott Wigglesworth, 22, of Rte. 2, La Plata, were both pronounced dead on arrival at Physicians' Memorial Hospital. Wolf was taken to Prince George's General Hospital, where he was listed in critical condition.

Sellner and Simpson were flown by helicopter to Children's Hospital in Washington, where they were listed last night in fair condition. Kristy Brown was flown to the intensive care unit of Prince George's General Hospital, where she was listed in critical condition.

Police said that no charges had been filed in the accident as of early today.

A Pentagon spokesman said that Brown had been in charge of teletype maintenance for Air Force Unit 2044, which is based at the Pentagon. Brown had been living in Waldorf with his wife and two daughters for approximately two years. Neighbors said that he frequently volunteered to drive the neighborhood children to their social activities with his daugther.
