A woman fell to her death at one of the RiverHouse apartment buildings in Pentagon City early Sunday morning.

A source tells ARLnow.com that the woman was intoxicated and walking on a restricted portion of the building’s rooftop when she fell through an old incinerator chute to her death. Police investigated the incident but no foul play is suspected and investigators believe it to be a “tragic accident,” we’re told.

No additional information is available about the accident at this time. An Arlington County Police spokesman declined comment.
