Has it been said what part of East St the remains were found on? One one end, it's close to where the grounds of Massasoit CC back up to Thatcher St, and at least in the 80s, there were paths in the little wooded area there and spots where teens would hang out and drink/smoke pot/get up to trouble (not saying how I know :innocent: ). On the other end, it's getting towards the Davis school and little subdivision type neighborhoods. You also have the convent and nursing home in the area (I did my confirmation service project at the nursing home), but I'd think that if an elder were missing they'd definitely be on NAMUS and have more publicity.
An odd spot for remains. It's not like its in a very well travelled area of the city, where there's stores or shops or other reasons to go up there by car, unless you lived up there or something. If there's a secluded spot there, you'd almost have to know its there beforehand.
Just trying to figure out why that spot/what would bring someone up there.
