NIAGARA FALLS, N.Y. (AP) — Body parts of a missing mother were found Sunday at an upstate New York park in Niagara Falls, police said.

The remains of homicide victim Loretta Gates, 30, were in a bag found floating in a lake at Hyde Park, Capt. William Thomson of the Niagara Falls Police Department said. Authorities have not said how she was killed.

The discovery comes two days after state police said a headless torso found near the base of Niagara Falls, the famous waterfalls, was the body of the missing mother.

Gates was living at her mother’s house in Niagara Falls when she disappeared the night of Aug. 25 after telling her mother she was going to a store across the street from their home.

Four days later, a tourist aboard a Maid of the Mist tour boat spotted the torso below the falls.

Gates had three children, ages 4, 5 and 11.

Investigators have determined her disappearance isn’t related to the death of a single mother whose badly decomposed torso was found last week in a suitcase in Lake Ontario. That woman’s other body parts were found scattered around Toronto last month, police said.

Toronto Police Const. Tony Vella said autopsy results showed she was Liu Guanghua, a Canadian citizen of Chinese descent.
