NIAGARA FALLS, Ontario (AP) — A woman’s torso found floating near the base of the Niagara Falls was likely in the water for four to 10 days, and the victim was murdered, police said today, as the discovery of a homicide victim’s remains in a waterway made headlines in Canada for the second time this month.

Police said the latest case is not related to body parts found in Toronto earlier in August. The murder victims have gotten extra attention because of the case of porn actor Luka Magnotta, who is accused of dismembering a Chinese student in Montreal and mailing his body parts to political parties and a school earlier this year.

Today, Niagara Police spokesman Derek Watson said passersby spotted a torso near the base of the Falls and police pulled the body out just past the Rainbow Bridge.

Niagara Police Inspector Jim Mccaffrey said the woman was a murder victim, but declined to reveal the cause of death. Mccaffrey said authorties have asked police in New York and Ontario to review missing-person files.

Police say they are asking for help in identifying the body.

Mccaffrey said it’s not uncommon to find body parts in the Niagara River. “That’s pretty fast moving water and it does have an effect on bodies in the water,” he said.

Police said the body is not connected to the murder victim whose body parts were strewn in two different parts of the Toronto area. Liu Guanghua’s head, foot and hands were discovered in a river west of Toronto earlier in mid-August. A few days later, her two calves, a thigh and an arm were found in a creek in eastern Toronto.  Her torso remains missing. Her estranged boyfriend was charged with murder last week.
