State police continue to look for clues in the murder of a North Salem socialite.

Divers searched the Titicus Reservoir and combed the brush around Lois Colley's 300-acre estate on Tuesday.

The reservoir is located across the street from the home where the 83-year-old was found dead last week on her laundry room floor.

Investigators believe she died from blunt force trauma, and that she was the victim of a homicide. A small fire extinguisher was missing from the home, though police won't say whether they believe it was used in Colley's death.

Colley's husband, Eugene, is known for his empire of roughly 100 McDonald's restaurants. Police say he isn't considered a suspect.

Anyone with information is asked to call the New York State Crime Stoppers hotline at 1-866-313-8477.
