In theory it's easy but first you have to create a corpse (execute a murder) and even then what you've described is still a logistical exercise involving multiple steps. Any mistakes you've made or witnesses there are will be magnified tenfold because solving murder cases is maybe the highest priority for detectives.
No kidding, and even leaving CSI fantasy land out of it forensics has come a long way. You better be sure not to drop a hair or a skin cell anywhere near the crime scene. Then there's the fact that there are cameras just about everywhere now.
