ST. CATHARINES, Ont. -- Police have found the body of a Niagara Falls, Ont. man missing and presumed murdered since late December.

The body of Alexander Fraser, 49, was recovered at about 6 p.m. ET Tuesday at the Sir Adam Beck Generating Station in Niagara Falls, police said.

Fraser had been missing since Boxing Day, when his burning car was found near the Niagara River in Fort Erie, Ont.

Since then, four people have been charged with killing him, even though his body was missing.

Victoria Harvey, 20, Brad MacGarvie, 25, Duran Wilson, 29, and Thomas Nagy, 25 -- all from Niagara Falls -- were charged with first-degree murder in January.
