Shrine to unknown person, 200 block of Zelma Avenue, Capitol Heights MD

While looking for a possible shrine built for Jan Cotto, who was slain in the 200 block of Zelma Ave, Capitol Heights, Maryland, on April 6, 2017, I encountered this older memorial in the immediate vicinity. This shrine appears briefly in a NBC news video. A child, Demetri Hooper, 6 months old, was also slain in this block in 2016.

I believe this shrine is possibly for an older incident. I cannot find anything on the situation.

Peace to these departed souls, and to this community.
