They mentioned that a call was made by an unidentified person.
Probably wrong but maybe it isn't murder but drug overdose and the third person there freaked out and ran away after calling.
I doubt some big pharma competitor decided to put a hit out on them. If it was a murder odds are it's something more common like love triangle, marital problems etc. Also, if it was murder wouldn't that have been fairly obvious rather than suspicious?
