An adolescent Queens girl helped save her family from four armed men who broke into their house last night. The intruders followed an18-year-old woman home and forced her inside at gunpoint around 7:30 p.m. The woman’s 13-year-old cousin hid in a closet and managed to call 911 while her parents and the 18-year-old were pistol-whipped by the intruders. Police say that the bad guys attempted to steal $4,000 and jewelry, but were caught as they escaped via the backyard. The men, all from the Bronx and named here, were charged with burglary, robbery, criminal use of firearm, unlawful imprisonment and criminal mischief.
