Police have stepped up their search for clues in an unsolved homicide.

Mark Werkheiser was found shot to death last week inside his home on Browns Road in Williams Twp., Northampton Co.

Police on Thursday conducted a search near the scene of the homicide, but they wouldn't say what they were looking for.

Werkheiser, 38, was supposed to appear at a custody hearing on the day he was killed, but the hearing was canceled when he didn't show up, officials said.

The mother of Werkheiser's children, Elizabeth Collazo, is a person of interest in the case, police said, but so far, no one has been arrested.
