Adaisha Miller of Detroit was killed at a weekend party when she was accidentally shot from an off-duty policeman's gun while she hugged him.

Detroit police said Miller was shot early Sunday morning. She was at the officer's home for a birthday, UPI reported. She was shot in the lung and heart and a died a local hospital.

Somehow in the course of dancing with the individual to his rear and touching his waist, his Detroit Police Department-issued weapon discharged one time, Chief Ralph Godbee said, KSAT reported.

Godbee, calling the death a very tragic, unfortunate incident, said that after an initial investigation it appears Officer Issac Parrish had not intended to shoot her. There was no evidence that the gun was even in his hand, but the internal affairs division will continue looking into the situation and present its findings to the Wayne County Prosecutor's Office.

Miller would have celebrated her 25th birthday on Monday.

It should not have happened, but it did, Godbee said.

Miller's mother, Yolanda McNair, said she is going to stay on top of the city's police department during the investigation, the Associated Press reported.

The story keeps changing, McNair said, according to the Detroit Free Press. There's no logical reason.

McNair said she was told her daughter was being a little flirty with the officer and they were hugging when she was shot and killed.

But she questioned why the officer had his gun on him.

Why do you need a weapon with a round in the chamber?, McNair said.

Miller's younger brother, Shane Miller, 23, is also demanding answers from the Detroit Police Department.

My sister is dead and you're alive walking around -- like you didn't even know what happened?, he said, according to the Detroit Free Press.

John Goldpaugh, a lawyer for the Detroit Police Officers Association, backed the chief.

This was just a freak accident, he said. They were having a party and the next thing, a woman is dead. He's devastated by what happened.

Golpaugh said the physical evidence corroborated with Parrish's account of the shooting. He also said the officer did not know Miller and was invited to the party with several other guests.
