Montgomery County authorities are looking for the hit-and-run driver or drivers who struck and killed a pedestrian early Sunday on South Warminster Road, between Mill Road and Surrey Lane in Hatboro. 25-year-old Rolando Dominguez-Villada of Horsham was struck and dragged along the road shortly after 2:30 Sunday morning.  Investigators believe more than one vehicle may have been involved, and one of them may have a damaged driver’s side mirror.  They are looking at the possibility that alcohol may have been a factor.  Any witnesses should call Hatboro Police.  The victim worked at the Ruby Tuesday restaurant in the Willow Grove Park Mall, and he leaves behind his wife, a two-year-old son and a three-year-old daughter.
