Body was floating in the river on Wednesday
An autopsy is under way, but first results indicated homicide
Case is unrelated to murder of Guang Hua Liu, police say
Deceased had a C-section at least once
The dismembered body of a woman has been found in the Niagara River, police in Canada said.
The torso, which had no head or limbs, was spotted by citizens on Wednesday and recovered by the Niagara Parks Police near the Rainbow Bridge near Niagara Falls.
Preliminary postmortem results indicated the woman was middle-aged, police said, and had at least one cesarean section and had her fallopian tubes tied.
Authorities said the homicide was unrelated to another case where the body parts of a woman named Guang Hua Liu were found in several places. Her torso is still missing.
Police expect the full results of an autopsy to be released Friday.
