A woman whose father was slain 8 1/2 years ago in Southeast Washington walked into a Virginia police station on Father's Day and told police she committed the crime, authorities said yesterday.

The woman, Elenor Mazaline Harris, 37, approached Chesterfield County, Va., police last Sunday and said she committed the December 1982 killing, authorities said. She was returned to the District yesterday and has been charged with second-degree murder while armed, D.C. police said.

"She indicated she wanted to turn herself in for the murder of her father," said Chesterfield County Police Sgt. Michael Spracker, who interviewed Harris. "She admitted to killing her father in 1982" during a domestic dispute, Spracker said.

The victim, Clinton G. Guy, was found unconscious in his bedroom by firefighters trying to extinguish a blaze at his house, on 53rd Place SE, D.C. police said.

At first, investigators believed Guy perished in the fire. But an autopsy revealed he had been shot several times and the case was ruled a homicide, police said.

A neighbor who has lived on 53rd Place for about 20 years said Harris was in the house with her two children when the fire started. She and her children managed to escape, and residents of the block wondered why Guy had been unable to flee the fire, said the neighbor, who did not want his name used.

"Many of the neighbors wondered why the case just seemed to be dropped," said the man. "There were some very strange circumstances that day."
