Derwin Christopher Barnhardt, 11, a Boy Scout who planned to enter Evans Junior High School here this fall, died Aug. 3 at the home of his father, William R. Barnhardt, in Landover. Derwin lived in Washington.

The Maryland state medical examiner's office said the cause of death was accidental hanging. A spokesman for the Prince George's County police said Derwin was playing with a brother at his father's house before his death. Derwin's body was found hanging by a bedsheet, which was tied to a pipe, in the laundry room of the house, police said.

Derwin was a native of Washington. He had completed the sixth grade at Shadd Elementary in Washington this year, where he served on the safety patrol and was a member of the softball team.

He was a member of Beulah Baptist Church of Deanwood Heights.

In addition to his father, survivors include his mother, Catherine Barnhardt of Washington; three brothers, Army Staff Sgt. Kevin Barnhardt of Landover, and Ralph and Andrew, both of Washington; his stepmother, Rachel D. Barnhardt of Landover; his grandmothers, Irene Thomas and Beatrice Johnson, and two great-grandmothers, Nottie Mae Harris and Geneva Hooks, all of Washington, and a great-grandfather, Allen Stroman, of Hyattsville.
