Call me naive, but unless MS is a deeply disturbed psychopath with no conscience (and he just doesn't come across that way, imho), what reason would he have had for murdering LB? Did he even know her? It was like this case, where it seems everything about it was related in DM's wishes and needs. He was said to have a sexual relationship with her, he was also seeing another girl at same time, he supplied LB with drugs, she seems to have been out of control, mentally ill, perhaps she was blackmailing/threatening him to help her (in whatever way, ie drugs, place to stay, money?) or she would spill to the girlfriend(s), and so she became a burden to him?
DM seems to have put everyone in his service, ie build an incinerator for me, help me steal plants for my property, machinery for my hangar, etc. He made empty promises to his friends to get them to help, ie he'd pay them (apparently not), he'd get them set up with a recording studio, he'd let them build a house on his property, he'd set them up in a lucrative home building business, etc, but nothing ever seemed to come to fruition for them.
I have no idea what they have on MS as far as LB's murder, but I feel like he's going to be able to beat that charge somehow. jmo
