If the Moscow police were being truthful with their initial release of info, on their website they stated,
"On November 13th, the surviving roommates summoned friends to the residence because they believed one of the second-floor victims had passed out and was not waking up. At 11:58 a.m., a 911 call requested aid for an unconscious person. The call was made from one of the surviving roommates’ cell phones inside the residence. Multiple people talked with the 911 dispatcher before Moscow Police arrived at the location. Officers entered the residence and found two victims on the second floor and two victims on the third floor."

This states that they called their friends because they thought someone was passed out/unconscious. Which again makes me wonder how they knew someone was passed out. It means someone had to have found the victims or at least one of the victims, right? Or it means DM knew something bad had happened and waited in her room until noon. If DM thought nothing bad happened then what made them call their friends then the police (again unless they found a body.)
