The body of a McKinley High School teacher was found with multiple stab wounds Monday afternoon at his Northwest Washington home, D.C. police said yesterday.

Police said they have no suspects in the slaying of Daniel Thomas White Jr., 39, who was found sprawled in the living room of his modest two-story, red-shingled house at 6510 Seventh Pl. NW. Neighbors, who grew worried after not seeing White or his car last weekend, called police.

The D.C. Medical Examiner's Office said yesterday that White died from massive bleeding caused by the stab wounds. Police said they believe he had been dead more than 24 hours before the body was found Monday at 5 p.m.

Detectives at White's house said the living room was in disarray and there were signs that White had struggled briefly with an assailant. They said they recovered White's car, a 1976 Opel, yesterday, but would not say where or specify what, if any, evidence they found.

Residents on the quiet residential street expressed shock yesterday at the death of White, a bachelor who lived alone. They characterized him as a pleasant but reserved neighbor who kept mostly to himself.

One neighbor, who asked not to be identified, said he heard "some commotion" two days before White's body was discovered "as if a chair had been thrown down the stairs or something."

White started teaching in the District public school system in 1972, first at Backus Junior High, then taught at Lincoln Junior High and Ballou Senior High before going to McKinley in February this year.

He taught social sciences and Afro-American history. White had also served as a counselor at Oak Hill, one of the city's detention facilities for juvenile delinquents in Laurel.

According to his mother, Josie White, he had received several awards for his work with inner-city youths, and the University of the District of Columbia cited him in May 1980 for his "contributions to the quality and advancement of education."

Henry Carter, who has lived in White's neighborhood for the last 16 years, said he had "never heard of anything like this happening before." He said White was a "very cultured person" whom "everybody liked . . . I know of no one who disliked him. That's why we were all so shocked to hear about it."

Isaac W. Jackson, assistant principal at McKinley High School, at Second and T streets NE, said that White was a "likable fellow" who was "always very pleasant." He said White was especially interested in school administration and that in addition to teaching his Afro-American history course, he helped monitor student attendance.

Neighbors said White had moved into the area about six years ago, taking over the house when his family moved out after his father's death. But they said they knew little else of his personal life since he apparently had few close friends in the neighborhood and kept to himself. "The whole time I never heard a peep out of that house," one neighbor said.
