I often delete messages too. Sometimes I don't mean to, but just do it automatically. However .....Many phones have a backup option, where if you delete a message.... you can go back in and retrieve it. (My phone happens to have that option). Sooooo, if her phone has that option and someone took the time to erase that back up deleted message - then malice or coverup involved - maybe just to cover up a mean message. If you know someones password, then you can access their phone from anywhere. You do not hae to physically be present and manually delete the message. In this case, you can call into the persons phone, access their messages and even write in the diary..... I don't know the politics in Coronado, but most politics are dirty and people can be bought. Always possible the message was terrible and would ruin them or their business if got out, that someone deleted the message and looked the other way.
You have to wonder why she never answered the call - simply missed the call or something else happening at the home. She could not have been dead, if it was her that checked the message at 1250. However, she could have been dead if someone else checked the message... I believe JS confirmed the call came from him, regarding MS taking turn for worse. Someone checked RN Voicemail at 1250. IF RN was the person checking the voicemail, then why didn't she call JS back.... Her phone was right there, so seemed like she wanted to stay in touch. So, does it mean that someone else checked the call and deleted it.
