Quick Summary

Demetrius Beatty, 40, from Washington, DC, has been charged with killing his girlfriend's 2-month-old infant daughter on August 16. Prosecutors claim Beatty beat the baby to death out of jealousy and then tried to frame his nonverbal autistic son by making a misleading 911 call. Police found Beatty holding the severely injured child when they arrived, and although he initially claimed the boy attacked her, forensic evidence showed the injuries were too severe for a child to cause.

Story summary

Demetrius Beatty, a 40-year-old man from Washington, D.C., is facing murder charges after allegedly beating his girlfriend's two-month-old daughter Khamyah Honesty to death on August 16. Police were called to an apartment building on New Jersey Avenue in Southeast Washington around 9:45 p.m. that night and found Beatty holding the unresponsive infant with severe injuries, including facial bruising, head trauma, and bleeding eyes. Khamyah was later pronounced dead at Children’s National Hospital.

A forensic pathologist confirmed non-accidental injuries on Khamyah, ruling out the possibility that they could have been inflicted by her six-year-old autistic brother. Prosecutors claim Beatty's actions were driven by jealousy over the child's father, another man with whom Beatty's girlfriend was involved while in a relationship with him.

Beatty initially provided police with shifting stories to cover his tracks, claiming he had made a phone call in the hallway or that the baby might have fallen during play. Court documents indicate previous threats from Beatty against the child’s mother if she left her babies alone with him. A relative of Khamyah's father had also been trying for two months to get city Child and Family Services Agency involved out of concern for the children’s safety.
