Carlos Alberto Perez Roque, 24, was shot and killed on the night of December 7, 2014, after police were called to a home in the unit block of Haines Court in Owings Mills, Maryland. The call came in about 9:20 p.m.; officers found him with at least one gunshot wound and medics pronounced him dead at the scene that night.

Investigators initially questioned people at the residence to reconstruct how an apparently ordinary evening turned fatal. Within two days police described the incident as a struggle over a handgun inside the Haines Court home: Roque and another man reportedly became entangled while fighting for control of the firearm, and Roque was shot once in the upper body during that confrontation.

Police identified and arrested Ramon Antoni B. Constanza, 31, of the same Haines Court block; reports said he was charged with second-degree murder and with using a firearm in the commission of a felony and was being held without bail. Does anyone who knew Carlos or was in that neighborhood that night have information that could help clarify what happened?
