Arlington County Police officers were dispatched to the 100 block of S. Glebe Road for an assault with injuries.
Arriving officers located one juvenile male suffering from minor injuries.
A police unit responding to the scene was flagged down by medics at the intersection of S. Glebe Road and 3rd Street S. where a second male victim suffering from numerous stab wounds was located.
The second victim, Dennis Adams, 46, of Arlington VA was transported to George Washington University Hospital Trauma Center where he was pronounced deceased.
The juvenile male was able to provide police with a detailed account of the events that occurred on April 1.
Through the course of the investigation, detectives uncovered a number of inconsistencies in the juvenile's account of these events and other evidence that lead them to believe his account was fabricated.
The Arlington County Police Department's Homicide/Robbery Unit has determined that this stabbing resulted from a domestic incident that took place in a residence in the 3600 block of 3rd Street S. Detectives have charged a 17-year-old relative of the victim with murder and stabbing while committing a felony.
