In my opinion I've made ny point. I feel no need to discuss peripheral details.
By pure coincidence, I watched a historical crime case last night on TV. It was about a doctor. He thought his wife was having an affair, and in a fit of rage, he killed her. Their housemaid had seen him do it, so he murdered her too.
He then set about cleaning up the crime scene. That included removing ALL identifying details with a scalpel (bit gruesome) and disarticulating the bodies. He stored the body parts in multiple plastic bags. Then he went back to his normal routine, with no one suspecting one murder let alone two.
After a while, the body parts were beginning to smell. He drove to Scotland, where he found a fast-flowing river, and tossed the body parts in. He thought the river would sweep the body parts into the sea, and thus he would be safe.
Once again, he went back to his normal routine, living in the house where he had committed the murders, and being visited by his patients.
They enquired about his wife. He told them that she had gone to visit relatives, which was her habit. Once more, he was functioning perfectly normally, and no-one suspected a reputable doctor of murder.
After more time had passed, thinking he was quite safe, the doctor went to the police to report her missing. He then made multiple enquiries regarding police progress.
How he got caught is a long story. Suffice it to say, the river into which he had thrown the body parts was in a flash flood at the time, but it rapidly subsided, and several of the bags lodged on the river banks. One had split open. A passerby saw a body part and the police were alerted.
After a complex reconstruction, the doctor was tried for two murders, found guilty, and was hanged.
