HILLTOWN, Pa.—Suburban Philadelphia authorities are seeking help from the public in tracking down suspects in a home invasion that left a resident dead.

Forty-eight-year-old Joseph Canazaro was killed and a woman and a teenager were tied up in the basement of the Hilltown Township home by a pair of masked gunmen who took bank books and weapons before driving away in the victim's pickup truck.

Bucks County District Attorney David Heckler tells KYW ( http://cbsloc.al/13TrXvc) that detectives are reviewing surveillance tapes from stores near where the truck was found. They are also trying to determine whether the suspects were dropped off at the home or came through the woods.

Police and federal agents are also trying to find out what guns the victim owned and where they might turn up.
