I see you digging on Sandra O'Neill. Posting a few digs for you.
This should add to what you are digging a bit. Some from last night and some from this afternoon. Lemme know if you are phone fagging and I can repost them so you don't have to zoom around.
long story short, found a connection between a Masonic "charity" group with 32 "mental health and rehab" houses/ one of which is in Ann Arundel County. No link with the shooter yet. but this afternoon I found a connection with this group (Arundel Lodge) and their home base in Arundel, ME (Kennebunkport adjacent) and a donor (O'Neill)
I see your Baltimore post. I also will find the dig I did about that house fire. which 45 (ahem) firefighters were required to put out and oddly the bodies were taken to Baltimore.
