Police are investigating a possible quadruple homicide in the Upstate New York city of Troy after four bodies were found in the basement of a home there.

The four bodies were found inside a home at 158 Second Ave. on Tuesday, Troy Police Sgt. Mark Maloy confirmed to TIME. Maloy said all four deaths are being treated as suspicious, but declined to offer further details on the investigation.

Troy Police Capt. Daniel DeWolf told the Albany Times Union that the building’s property manager was the first to discover the bodies in the residence, but no other details about the victims have been released.

“It’s horrible. Terrible. Sad — sad especially at this time of year,” DeWolf said. “We’re going to do everything we can to look into this and get to the bottom of what happened here.”

A block of Second Avenue has reportedly been shut down while police investigate.
