The remains of a woman reported missing four years ago were found in her New York City home after the new owner sent a cleaning crew to the house.

Until last week, no one apparently knew what happened to 83-year-old Florence Bock. She was found on Friday, said police Sgt. Carlos Nieves.

The house in the Bronx was purchased recently by a developer after the missing woman was declared dead, police said.

The cleaning crew found Bock's remains — a pile of bones, including a skull, lying next to a cane.

The medical examiner's office was expected to examine the bones Sunday for clues to how she may have died. Investigators said they do not believe Bock's death was suspicious.
