No flames from me, friend, but I want to share my experience, which I posted right after joining WS. I live in a senior apartment complex and my close friend and neighbor died in her bed on a Sunday or at the latest Monday. My front door is 30 feet from her front door. It took until Thursday for the smell to become noticeable and raise the alarm. This is in California with temperatures in the 60's.
The coroner did not arrive for another twelve hours during which time they posted a policeman at her front door to keep people out. By Friday the smell was noticeable on the floor beneath ours as well as in our hall.
Just letting you know... On the subject of the roommates, there is another explanation. Mormons are expected to tell the bishop if they see any improprieties going on. Every family, for example, has a home teacher who visits once a month and reports back to the bishop if anything is noticed which indicates the members are having "problems" with their faith. This would include visible beer cans, cigarettes, or if the family reports any concerns that the ward could help with.
What this means when you are single is that everybody is watching you. I was reported for having a strange car in my driveway overnight. The bishop called me and asked me whose car that was. I was reported for having "men" driving up to my house all hours of the night. I had four grown sons who worked night shift and I babysat for them. I am sharing this because MINDING YOUR OWN BUSINESS is the way to avoid violating the expectation of your to rat on your friends.
It is perfectly consistent with their self-interest that Travis' roommates would not want to know what was going on in his private bedroom. Even if they knew there were improprieties going on, they don't want to tell the bishop and have the bishop call him and say, "It has been reported that you are having lady friends stay overnight." Travis would know immediately it was a roommate who reported him.
They looked the other way.
You can see this dynamic in action with Jodi's roommate Rachel. She did not report Jodi's statement of having oral sex with Travis to the bishop. Instead, she eloped and told Jodi she would have to leave for that reason. She did not want to piss her off because I am 100% certain the entire ward knew exactly who slashed Travis' and Lisa's tires--they knew she was DANGEROUS.
In fact, I agree with those who are worried about witnesses should she be paroled at any time.
