According to police, officers conducted a welfare check at the couple's home in Northwest D.C. on Friday. When they arrived they found a man, identified as 51-year-old Jason Rieff, with a handgun who appeared to fire a self-inflicted shot while they were on the scene. Authorities said they also found an unresponsive adult female identified as 45-year-old Lola Gulomova.
