MASSAPEQUA PARK, Long Island (WABC) -- Detectives are now looking into whether any of the Gilgo Beach murders may have been carried out at the family home of suspect Rex Heuermann.

Evidence technicians will be scouring Heuermann's Massapequa Park home for an eighth consecutive day on Friday. The search of the house is expected to last at least another two days, a law enforcement official familiar with the search told ABC News.

Meantime, unsolved murders and missing persons cases "around the nation" are getting a second look a week after Rex Heuermann's arrest for the murders of three young women whose burlap wrapped bodies were found along Gilgo Beach, Suffolk County Police Commissioner Rodney Harrison said.

That includes the 2006 killings of four women working as prostitutes in Atlantic City. Their bodies were found in a watery ditch along Black Horse Pike in Egg Harbor Township, New Jersey.

Police in Las Vegas, where Heuermann owned a timeshare, said this week they are also looking at possible connections to unsolved cases.

"We are working with partner law enforcement agencies, obviously the FBI continues to be engaged, to see if there are any other connections that need to be made," Suffolk County Executive Steve Bellone said Thursday. "I can tell you this: the investigation continues. We will remain and our police department will remain focused on bringing justice for our other victims."
