An older man was found dead yesterday under mysterious circumstances in The Bronx, authorities said.

The 62-year-old victim was discovered around 10:40 p.m. after someone made a 911 call of a foul odor coming from the Davidson Avenue home, cops said.

Emergency workers responded and found the victim inside. He appears to have suffered from severe trauma to the head, police said.

It is not clear how long the man had been there or what might have happened, cops said. There was no sign of forced entry to the home, police sources said.

The cause of death is pending an autopsy by the city’s medical examiner, police said.
