The suspect in the Gilgo Beach serial killings lives in a dilapidated home in a Long Island suburb.

Architect Rex Heuermann, 59, was charged on Friday in three murders and is the prime suspect in another. He resided in an unkempt, red house in the suburban town of Massapequa Park, NY, with his wife and two children. The single-story home is about an hour train ride from New York City on the southern shore of Long Island—just across the bay from the coastal road where bodies of at least 11 victims were discovered.

“It was weird. He looked like a businessman,” neighbor Barry Auslander told the Associated Press. “But his house is a dump.”

The identity of the serial killer has puzzled law enforcement for more than a decade. The remains of 11 bodies were discovered along Ocean Parkway near Gilgo Beach in Long Island from 2010 to 2011. The victims included a man and a toddler, but most were young, female sex workers.

Investigators do not believe all of the murders were committed by the same individual. The Netflix film “Lost Girls” was based on the unsolved murders.

Heuermann founded RH Consultants & Associates, a Manhattan-based architecture firm in 1994. It counted American Airlines, Catholic Charities, and New York City’s Department of Environmental Protection among its clients, according to the firm’s website.

However, Heuermann lives in a modest home with an overgrown yard that he purchased for $170,000 in 1994, according to property records. The home, built in 1956, is now worth at least nearly $600,000, according to estimates on Realtor.com®. The home is surrounded by much larger, nicer homes.

“It’s a very quiet neighborhood. At night, you could hear a pin drop,” Heuermann’s next-door neighbor Patrica Maressa told CBS News.

She told NBC that it appeared that the family was redoing the front of the house, putting in a new door and windows.

“This house sticks out like a sore thumb. There were overgrown shrubs. There was always wood in front of the house,” neighbor Gabriella Libardi told the Associated Press. “It was very creepy. I wouldn’t send my child there.”
