Dave sacrificed him to the Straight Edge cult in the heart of Washington D.C. headed by Ian Mackaye
If you do some of the research you'll realize he lived in Arlington as a teenager and played in Dischord band Scream
Straight Edge was always a government psyop. Mackaye's dad was CIA. So there's no doubt there's some fishy shit and deaths, see also Freak Smith from Beefeater who's death was never explained at all.
