Police are on the hunt for a single gunman that shot five people in Maryland this morning, killing three.

Law enforcement believes Radee Labeeb Prince, 37, opened fire at employees of Advanced Granite Solutions at the Emmorton Business Park in Edgewood, Maryland just before 9 am local time.  Officers arrived just four minutes later, but were unable to apprehend the subject.  Three of the victims were killed, with two others rushed to a local hospital where they are both currently listed in critical condition.

“We do not believe there’s an immediate threat to the community — we do believe that this was targeted, with the qualifier that there is an armed and dangerous suspect out there,” Harford County Sheriff Jeffrey Gahler told reporters. “There’s an individual out there on the loose who committed one of the most heinous acts we’ve ever seen in our county. Certainly we consider him armed and dangerous.”

Authorities believe Prince escaped the scene of the shooting in a black 2008 GMC Acadia with the Delaware license plate PC064273.  He remains at large and police warn that he should not be approached.  If anyone sees Prince, they should immediately call 911.
