I’m so sorry to hear that GeoPie... Thank you for sharing what you know with us. I hope the police can get some answers for all of you as to who this person was and why this happened (although I know answers won’t take away your pain).
Everyone affected by this tragedy will be in my prayers, and I’ll be praying for your SIL’s brother and your whole family as well... May the L-rd gather you all in his loving embrace and bless you with strength and comfort during this time.
I realized I may have misinterpreted your post... Was your SIL’s brother involved in the shooting in Arvada, or another incident? Regardless I will still be praying...
