Burned pile of stuff near Alewife (attack on homeless person?)

[squirrelitude]

A couple of hours ago I was walking along the bike path next to the eastern Alewife head house and saw a pile of scattered, burned items covering one side of the path with police tape blocking it off. (Uncharacteristically, I neglected to take photos.) There were several notes nearby that lead me to believe this was some kind of attack on the homeless guy I've seen sitting there, in which his cart was burned -- but that is only speculation. Does anyone have any actual information on this?
