Teen Charged in Chilling Baltimore Sibling Murders Sparks Widespread Outrage

A teenager was arrested Wednesday in connection with the fatal shooting of siblings inside their home in a suburb of Baltimore County.

Keith Maurice James Jr., 16, was charged with two counts of first-degree murder and one count of use of a firearm in a crime of violence as an adult in the July 7 shooting deaths of 9-year-old Steve Allen and his 15-year-old sister, Giovanna Myrie, inside their Gwynn Oak house, police said. The children's mother found them dead and called 9-1-1, according to the criminal complaint.

Baltimore County Police Chief Robert McCullough said Wednesday investigators discovered that James was inside the house previously, and the criminal complaint alleges the suspect was hanging out with Myrie inside the house with a gun in the days leading up to the killings.
