This photo actually jogs my memory and puts some pieces together:
July 3
2:56 pm - MJW texts DM - if all goes as planned you'll have domes tonight for the 500 we agree'd
6:19pm - DM texts MJW - it says '32 long' on the side of it. can send pic as soon I'm home
Which is obviously this photo - and about getting ammo.
7:33pm - DM texts MS - tru. I'm on a mission back in 1 hr.
I think this is DM going to out to get ammo he's discussed with MWJ.
Radio silence on the phones from this point until 12:42am. Some point soon after DM gets back, he and/or MS kill LB.
After they kill her - MS goes to the basement and starts low key freaking out. Asks where DM is, if he's going to sleep and if he can come talk to him. Meanwhile DM has gotten high and has no worries.
