I'm beginning to think that Madeline was killed the night of Sunday, 25 Feb 2024, at SS's place at 4012 Santa Maria Drive, Kissimmee, FL. The Kissimmee Police Department is now the lead investigating agency. Madeline's home was in the Hunter's Creek Community, located in an unincorporated area of Orange County, FL. Her school is also located in Orange County.
So, he deposited her backpack and laptop in her own apartment complex dumpster at 7:35 a.m. Then, he left to drive to his place in Kissimmee, FL to get Madeline. She was already dead, but he wanted to make it seem that he had stopped at her home to pick her up -- even though she was already in his vehicle and deceased. That's why he wasn't seen returning until 8:19 a.m. He had driven to his home to get her body. [Does he have a garage?]
From there, he drove somewhere to dispose of her body. [Just a theory -- probably wrong!]
