Tillicum,
Your explanation makes so much sense and I thank you for it. I was confused when the FBI Silver Alert, issued on Tuesday, March 19, included, "Police say Amiah Robertson is believed to be in extreme danger and may require medical assistance."
That alert went out at the same time that reporter Steve Jefferson (WTHR Channel 13) did a spot showing two views of the home below. Jefferson said this house, at 229 S. Holmes Avenue, is where Amiah was supposed to be taken to the sitter. The first picture is of the front of that home.
Steve Jefferson said a search was being conducted there that involved vans from both homicide and crime lab units. You can see a forensics service van in the first photo.
Steve said the search was focused at the back of the home. The second photo is of where the search was focused. We know they removed several bags of items from this location. The Silver Alert was issued simultaneously with this search.
To Tillicum's point, it seems likely they found blood or other evidence that Amiah may have been gravely injured in this location. Members of Amber's family have said that Amber lives in the "shed" in back of this house. I don't know if anyone else lives there with her. I surmise they are referring to the building right at the back of the house in the second photo.
This is the same location where a neighbor who lives across the street saw Amber and Amiah on Friday, 3/15, at 9pm. "I definitely saw her Friday night around 9 p.m.," Beatty told News 8. "[Amiah] had a short T-shirt on, probably some thin pajama pants, no jacket and it was cold. The mom was just holding her up [away from her body, instead of cradling her] and was speed walking with her."
These same neighbors have a surveillance camera and they turned the camera's footage over to LE.
