I know nothing of the particulars of this case, but a person could order a fake hit and then kill themselves in order to make it look like a murder to ensure the life insurance payout.
That's about as criminal as murdering someone though.
There's nothing for the police to stand beside, behind, in front of or crouch and whimper inside of in this case.
If the one ordered to do the killing knows the target is the one ordering the kill and the target is of a sound mind, I would call it assisted suicide (https://en.wikipedia.org/wiki/Assisted_death), and I wouldn’t call what the killer did murder.
