Habitual Felon Arrested in Triple Murder:  A Delaware man with 15 felony convictions was arrested yesterday for shooting five people at a small business in Maryland and the owner of a car dealership in Delaware, leaving three people dead.  Justin Fenton and Talia Richman of the Baltimore Sun report that state and federal officers tracked Radee Prince from Maryland to Wilmington, Del., after a man fitting his description shot the car dealer in the head.  That victim is expected to survive.  Prince had worked at the Maryland kitchen countertop company and is believed to have targeted the employees he shot.  Police believe that he also knew the car dealer as well.  Prince, who has been arrested 42 times, pled guilty to 15 counts of burglary in 2003 and had been charged with several handgun violations in 2015.
