ST. CATHERINES, Ontario (AP) - Police say there is a good possibility that a murder victim's torso found floating near Niagara Falls last week could have come from the U.S.

They are calling on the public to check on female family members, co-workers or neighbors they haven't heard from in some time.

A tourist spotted the torso near the base of the falls Wednesday.

New York State Capt. Steven Ingrelli said Tuesday that because the U.S. shares the river with Canada, it's possible the person may have entered the water from there.

Police have said the case is not related to body parts found in Toronto earlier in August. Such cases have received extra attention after porn actor Luka Magnotta was accused of dismembering a Chinese student in Montreal and mailing his body parts to political parties and a school earlier this year.
