Police say the human torso found floating in the Niagara River on Aug. 29 was that of Loretta Jo Gates, 30, of Niagara Falls, N.Y. (Erie County Central Police)

Body parts of a missing mother whose torso was found floating at the bottom of Niagara Falls were found at a park in the upstate New York city, 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 Sunday. 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 Guang Hua Liu, a Canadian citizen of Chinese descent. Her estranged boyfriend was charged with murder last month.

A man charged with her murder made a brief court appearance Monday.

Chun Qi Jiang, 40, wore a dark orange T-shirt and brown slacks and fidgeted in the prisoner's box. He was remanded into custody and is scheduled to return to court on Oct. 16.

Jiang was arrested Aug. 26 and charged with second-degree murder.

The two cases have gotten extra attention since 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.
