This gets worse, the above article says that Shanequa's own mother was murdered in 2006 when Shanequa was just 11 years old. So the grandmother Celeste Seabrum had already gone through losing her daughter or daughter-in-law before this. It seems offhand to have just informed Mrs Seabrum over the phone that Shanequa had been found deceased in the river, wouldn't police visit under those circumstances?
Not a lot of clear information out there at the moment. I know that if a body has been deceased for a while the extremities and head can begin to detach by themselves. Perhaps that is the case here. Hopefully the autopsy will be able to tell how long Shanequa had been in the water and cause of death. I think an accident here is pretty unlikely so far from the airport? Foul play looks much more likely.
It would be interesting to know just what was done and how quickly to try and find Shanequa, as an extra vulnerable young woman on her own in those important first few days. And why, as the grandmother says was she not caught on CCTV again around the area, was it all checked? It seems like Shanequa had a significant learning disability as well as autism, people who know her well will probably know what actions she might have taken when her card didn't work. Probably go back and find someone she knows and ask for help? Or might she have unsuspectingly asked a stranger for help?
I worked a lot with people with learning disabilities when I was younger and when setting up and teaching a travel routine or any other routine the difficulty is is how safe/predictable is a person when that routine breaks down and something unexpected happens. That's much harder to teach and cover every eventuality. And sizing up people as to who to ask for help and who not to ask, very difficult and harder to practise and remember. I wonder if Shanequa had a phone with her.
