The I-95 killer: Could one murder be linked to another?

They're both elderly victims of gruesome murders found dead in their expensive homes, they're both owners of fast food franchises, and they're both leaving investigators stumped on who did it and why.

But, could the murder of Westchester socialite Lois Colley possibly be linked to a double homicide more than 900 miles away?  That's the question one sheriff in Georgia is asking since he heard about Colley's killing in November.

"Ever since the Dermond murders occurred here we are actively are seeking any kind of elderly murder case in the country, especially in a wealthy, exclusive community," said Putnam County Sheriff Howard Sills.

Sills is on the hunt for the killer of Russell and Shirley Dermond. The couple, ages 88 and 87, were found dead in their Georgia home in May 2014.  Russell's body was discovered beheaded in the garage.

It's circumstantial evidence not too different from the murder of Lois Colley in North Salem, NY, where police found the elderly woman bludgeoned to death in her laundry room. 

There's still no word on a suspect, motive, or the exact weapon that was used.

Sills says those similarities led NY investigators to call him looking for to answers.

"They asked me was there a New York connection," Sills said. "Mrs. Dermond was originally from NYC and she moved away from there after college. She had a son who was murdered in 2000 and he was arrested in Nassau County. That's the only New York connection I can find. "

Sills says it's still not enough to connect the two cases, but adds he'll be interested to learn what comes of the Westchester murder.
