Here is a Michael Brewer that is associated with Comet Ping Pong: https://myspace.com/cometpingpongdc/connections/out who possibly worked there.

His friend Jimmy Pelletier, who is shown here playing ping pong at Comet Ping Pong on his channel https://www.youtube.com/watch?v=tqg928CLV70, runs a children's charity called DC wheels. https://www.facebook.com/TheDCWheels

These children's charities are often suspect and since this is directly tied to CPP, I wanted to point this place out again. I've noticed some ties of skateboarding to child trafficking in a lot of my other research.
