Police have found the charred remains of a retired FBI (search) agent's daughter who disappeared nearly a month ago, authorities said Saturday.

The remains were identified as those of Deanna Wright McIntosh (search), 15, who was last seen with a friend at a nail salon near her home in suburban Yeadon on Dec. 3, prosecutors said. The girl's death has been ruled a homicide.

Police said they have questioned a man who tipped off investigators about the remains, which were found Thursday in a rusted steel drum in West Philadelphia. Prosecutors declined to say Saturday whether the man is a suspect.

The girl's father, Jim McIntosh (search), retired from the Philadelphia bureau of the FBI about two years ago. Detectives said they do not believe the slaying was related to her father's work.

The girl's family does not have a listed number and could not be reached for comment Saturday.
