Charging documents in Tuesday's shooting in Pigtown that left a young couple dead and two others seriously wounded show that the attack stemmed from a dispute over $10.
Melville Mason, 35, was formally charged with two counts of first-degree murder, four counts of attempted first-degree murder and numerous other charges, and is being held without bail in the killings of William Monroe and Meaghan Kerrigan.
Court records show that officers responding to the scene inside a home in the 1200 block of S. Carey St. found Kerrigan's one-year-old daughter, who was unharmed, sitting next to her body, patting her on the back.
Witnesses told police that Mason, known as "P.J.," broke into the home through a first-floor window propped open with a window fan and began firing, killing Monroe and Kerrigan, injuring two women, and firing at another woman and the infant. Mason allegedly left the home, obtained a new handgun, and returned through the same window and began firing again.
Inside, according to witnesses, he was heard saying he was a "Creeper" and that "This is your worst nightmare." WMAR-2 interviewed a next door neighbor Tuesday who said Mason was overheard saying, "I am the Reaper."
Police said that Mason and "an occupant" of the Carey Street home had been in a dispute over money, with witnesses indicating that Mason was owed $10, charging documents say.
