From what I've read about Tim Bosma, he would not put up a fight. He would just want to be dropped off unharmed somewhere. I think DM pulled the trigger and fast. I don't even think Tim knew what was happening (at least in my mind I hope he didn't suffer). DM is such a psycho that he just pulled the trigger and didn't care, hence all the blood that was everywhere. MS knew exactly what was going to happen otherwise he wouldn't have brought a change of clothes as Millard requested. The gun had to have been DM's because he took it home with him. He then dropped it off in his own toolbox. If it was MS' gun, he would have it with him. I don't even think MS had a gun otherwise he wouldn't be trying to sell DM's for money to get a lawyer. DM is trying to frame MS by telling CN that he had to clean up Smich's mess but Millard lied to CN all the time so this is no different.
