A 19-year-old Andover resident was charged this morning with using a pistol to beat two other teens over a dispute at a Super Bowl party held at the Ritz-Carlton last night, Suffolk County District Attorney Daniel F. Conley said.

KEVIN S. MACARTNEY (D.O.B. 11/6/92) was arraigned in the Boston Municipal Court on two counts of assault and battery with a dangerous weapon for the incident, which left two Peabody youths with head injuries. Macartney was also charged with unlawful possession of Class B and Class E substances for pills recovered from his clothing when he was booked.

Assistant District Attorney Spencer Lord recommended that Macartney be held on $20,000 cash bail. Judge Thomas C. Horgan set bail at $5,000.

The victims, both 19-year-old males, approached Boston Police last night at about 10:30 p.m. and complained of being assaulted by a group of young men as they left a party at the downtown hotel. The victims told police they were accused of stealing liquor, and that one of those men had struck them in the head with a handgun during that confrontation.

With the victims, the officers made their way to the Ritz-Carlton residences and encountered a group in the lobby. The victims identified members of that group as having been at the party and further identified Macartney as being the one who beat them.

The officers noted the presence of what appeared to be blood, not only in the lobby but also in the elevator, on the hallway rug on an upper floor leading from the elevator to the room in which the party was held, and inside the room itself, which detectives visited and ordered frozen pending the issuance of a search warrant.

Macartney was arrested at the scene. During the booking process, additional officers recovered 21 pills from a bottle with no prescription information on it. Those pills were believed to be Oxycodone, Focalin, and Alprazolam.

Macartney was represented by attorney Thomas Barbar and will return to court on March 27.
