PHILADELPHIA (CBS) – The investigation into a murder in Hilltown Township, Bucks County is continuing with painstaking detail.

Bucks County District Attorney David Heckler says there is plenty of evidence in this murder investigation, and still many unanswered questions as to who killed 48-year-old Joseph Canazaro (see previous stories).

Heckler says detectives are reviewing surveillance videos from stores near where Canazaro pickup truck was found. Police, FBI and ATF agents are also looking for information on what guns the victim owned and where they might turn up.

Distict Attorney Heckler says police are also trying to determine how the suspects go to the home: were they dropped off at the property or did they come through the woods?

Heckler says an autopsy was conducted on Canazaro but the cause of death is not being revealed. He expects more information on the case to be available in the coming days.
