A community in Richmond, Virginia, is reeling after an eight-year-old boy was beaten to death while trying to protect his 12-year-old sister from a rapist.
The boy, identified as Martin Cobb, was pronounced dead at the scene in the 200 block of Brandon Road Thursday night. His sibling was taken to a hospital.
At around 6.30pm Thursday, the brother and sister were playing by the train tracks near their home when a stranger approached the 12-year-old girl, sexually assaulted her and slashed her face, the kids’ aunt and stepfather told WRIC.
When her 8-year-old brother tried to intervene, the teenage attacker turned on him, throwing a rock at his head. Martin died instantly.
