It'll be interesting to find out what happened. Strange that those two roommates weren't aware that people were being murdered in their home. Clearly it wasn't a break-in then.
@pianoplayingsteve I heard they are speculating the murderer entered by way of a sliding glass door. I don't understand why they are not saying who called 911 to report the murders. I assume it would have had to be one of the survivors. Whoever did it was harboring a lot of pent-up anger. Also, I heard today that the sister of one of the victims (the Goncalves girl) stated that victim had tried to call some phone number about a dozen times within a thirty-minute period. This was about an hour or two before the murders.
Attended there a couple times and have a Masters from UI. Moscow ( Mos-coh... There is no 🐄 in Moscow was a saying years back) was always a sweet, pretty, sleepy town, but that has been ruined.
