NEW YORK — Security footage shows an unidentified man walking into the Queens home of an FDNY paramedic’s elderly parents shortly before a fire broke out on Sept. 8.

After firefighters extinguished the blaze, they found the 77-year-old husband dead and chained in the basement and his 78-year-old wife dead on the first floor, the New York Post reported.

The NYPD confirmed that the fire is being treated as a double homicide, without speculating on a possible motive.

Surveillance video shows an unknown man entering the house through the back door at 10:15 a.m. and leaving at 3:08 p.m., just 14 minutes before fire alarms sounded.

The couple’s off-duty FDNY paramedic son rushed over after neighbors told him about the fire. Trending
