On June 9, a 13-year old boy walked into his Cambria Heights, Queens house shortly after noon, looking for lunch.

Instead, he discovered his mother, father and aunt all shot dead. The entire working class neighborhood was shocked.

Today, the Queens D.A.'s office said cops have cracked the case. They've charged Sandra Powell, 39, with murder and are looking for her accomplice.

Say prosecutors:

District Attorney Brown said, “According to the charges, the defendant acted together with an unapprehended individual who shot and killed a man, his wife and his sister-in-law during the commission of a burglary and an attempted robbery. The horrific crime scene was discovered by the couple’s 13-year-old son who had come home from school for lunch.”

District Attorney Brown identified the defendant as Sandra Powell, 36, of 69-38 Thursby Avenue in Far Rockaway, Queens. She has been charged with Murder in the Second Degree, Burglary in the First Degree, Attempted Robbery in the First Degree and Criminal Possession of a Weapon in the Second and Third Degree and faces up to life in prison if convicted. The defendant was arraigned yesterday in Queens County Criminal Court before Judge Seth L. Marvin who remanded her without bail and set a return date of December 8, 2003.

The District Attorney said that according to a criminal complaint, the defendant acted in concert with an unapprehended other who intentionally fired a loaded firearm at Larrie Barnes, 39, Carren Chambers, 34, and Tisha Chambers, 21, between 8:30 a.m. and 12:15 p.m. on June 9, 2003 inside their residence at 236-18 120th Avenue in Cambria Heights, causing their deaths.

She wasn't charged with First Degree murder, which carries a possible death sentence upon conviction.
