That was one fucked up case, his severed head was found in a frozen river, scalped and toothless. Some of its soft tissue and the lower jaw had been torn off. He was partially cannibalized.

The fuck? What happened to that sick asshole who perpetrated the deed? Hope he had a suitable punishment.

He was sentenced and was put into an institution for the criminally insane. He died in 2007. He escaped twice while on a vacation from the prison. He had been planning a similar crime, and almost managed to carry it out while being on the run.
He never confessed to the murder, and it is suspected that he had had more victims besides Hannu.
Before Hannu's murder he was accused of attempted murder but only got convicted of aggravated coercion. While pretending to be a doctor, he put a knife on a guy's throat, rode him like a pony and told him he would cut his throat, rape and then dismember him.
He drugged him with ether, he regained consciousness, was stabbed a couple of times but then managed to escape.

The mini-LP "Night Fight" was released ONLY in Finland, not Sweden as the description states. The band did't even move there until +1 years after this release. Remember when the mini-lp came out and was sold mainly at local records stores in band's hometown in Finland.
