From [HERE] and [HERE] Every month since her brother was shot and killed by police last year, Priscilla Johnson has gone back to the Northwest Baltimore neighborhood where he died to hand out fliers, begging for anyone who saw something to come forward.

What his family knows, gleaned largely from media reports, is that Dennis Gregory was a bystander who was shot by detectives who were aiming for his friend Glenn Brooks. And they know from the autopsy that Gregory was hit four times in the back.

What they didn’t know is that Gregory was acting as a confidential informant that night and that it was his call to police to report that Brooks had a handgun that summoned them to the scene in the first place . The revelation is contained for the first time in court documents filed in federal court late last month and obtained by The Baltimore Sun.

It’s the biggest breakthrough yet in the family’s quest to understand the events of that night. Calls to detectives and visits to police headquarters have gone unacknowledged, and they’ve found little cooperation from the neighborhood.
