Murder would be one of the last things I would think about. My immediate thought if my big boyfriend did the same thing would be he is in a ditch somewhere or drove off a bridge OR he ran away/left me in a close second. Big men aren't really like 90 pound females where someone, on the spur of the moment, may decide to grab them and shove them into trunks.
To me, that means something isn't being said. Like, if I knew my boyfriend was involved with some bad people for whatever reason I may be a lot more likely to think murder immediately. Him lying about being on duty for work would make me think that he knew something was up too-either that he would be leaving or that he knew people were after him?
I wonder if the daily heart medication is something that NEEDS to be taken every day or more of a preventative. I know a lot of people who take daily heart-related pills, but it isn't because they will explode if they don't for one day. Depending on that answer, I will lean one way or the other.
