Around 6:45 a.m. Wednesday, Feb. 8, Oscar Ramirez, Marvin Roach, Thermon Brewster and other men emerged from the hypothermia shelter at Rising Hope United Methodist Mission Church on Russell Road in the Mount Vernon Area of Alexandria. When they began traversing the parking lot towards the Aldi grocery store, opposite the church, a flurry of at least half a dozen unmarked police cars descended on the group, the men said.
