A man has been charged in connection with what police described as a "particularly heinous" killing of a Washington DC resident who was found bound and set on fire in his apartment.

Rico Rashaad Barnes was arrested for the robbery-murder of Syed Hammad Hussain. According to police, Hussain's DC apartment was ransacked and set ablaze after his death.

Authorities discovered Hussain's body bound in the burned apartment located in an upscale area of the city. The incident has been classified as both a robbery and murder case.

Police have identified a second suspect in connection with the case, who is already in custody on unrelated charges. That individual is expected to be charged in relation to Hussain's death.

The investigation into the circumstances surrounding the killing remains ongoing. No additional details about the motive or timeline of events have been released by authorities.
