The person, described by police as a person of interest, wore a "Elmer Fudd-like" lumberjack hat and a baseball cap as the person dropped off a package at Jim Alden's apartment along Pine Street -- not far from Rittenhouse Square.

They also stressed that it appeared to be a targeted attack but they aren't sure if the person of interest simply delivered the device or manufactured it as well.
