ALLENTOWN, Pa.—Authorities in eastern Pennsylvania say autopsies are planned to try to find out what killed two men who were found dead in an Allentown home.

Officials in Lehigh County say the victims, whose names haven't been released, were found just before 6 p.m. Wednesday in south Allentown.

District Attorney Jim Martin said there were no obvious signs of trauma on the bodies so it isn't clear what killed the men, who were roommates.

The county coroner's office called the deaths suspicious and said autopsies were planned Thursday.
