For those interested,
I live in that area and here's what I can gather. Sheddrick Miller was baptized just 3 years ago. He claimed to be of the "anointed" and partook at the memorial for the first time last year. Kia, his wife, had apparently been a witness all her life. I was told that no one was able to get in contact with them for 2 weeks and their cars hadn't moved. The last thing the wife posted on her Instagram was from 2 weeks ago. It's likely they were in that house longer than a few days. They were apparently going on vacation to Jamaica for a week, but then no one heard from them again. That's why no one looked into it sooner until the grandmother broke into the house to find them all dead.
