A creepy-yet interesting case I think you people might already heard from. The Italian Unabomber. I find him intriguing, mainly because of his disguised booby-trap bombs in innocent objects and his mysterious thrill to committ the bombings.
Short description from Wikipedia:
"The Italian Unabomber placed small booby-trapped objects in public spaces in Veneto and Friuli-Venezia Giulia which were designed to detonate when handled by a passerby and seriously injure but not kill the victim. The Italian Unabomber was named by the international press in reference to Ted Kaczynski, the American Neo-Luddite terrorist and mail bomber known as the "Unabomber", but the Italian bomber made no political or economic demands. Over 20 explosive devices were attributed to the Italian Unabomber and resulted in numerous people receiving injuries including the removal of digits and limbs.
On August 28, 2006, Italian police raided the house of Elvo Zornitta, a 49-year-old engineer, who had been under surveillance for a year with assistance from the United States' Federal Bureau of Investigation. In January 2009, after years of investigations, the case was dropped after the prosecutors asked for its dismissal, for lack of evidence. Zornitta received €2,500,000 as compensation for his arrest and trial which included false evidence."

I found a write-up on UnresolvedMysteries subreddit on Reddit that's really informative: Monabomber: booby trapped nutella jars and votive candles (reddit)
A particular incident which caught my attention was the egg bomb, described below:
"A man buys an egg carton at the supermarket "Continente" of Portogruaro. When he brings it home, he notices wires coming from the carton. He contacts the police, who find that one of the eggs had been boiled, cut in half, filled with an explosive device and glued back together before being put on the shelf again."
In 2004 Elvo Zornitta had his house searched and after another suspect had described him as a "bomb expert", they subsequently find household items that were compatible with items used by Monabomber, like empty BIC pens and bottles of a popular brand of vanilla essence, both of which had been used by the bomber. They also find firecrackers that were missing their gun powder — Zornitta justified them by saying that he had tried to DIY a firework fountain, which didn’t work out.
However, DNA found in the egg from 2000 did not match Zornitta. Plus, the man had a solid alibi for at least two of the attacks.
Zornitta's defense lawyer requests another toolmark analysis, especially of the very first pictures taken of the bomb in 2004. What they find is shocking: no cuts were found in the first pictures - the cuts had been added after the scissors had been retrieved from Zornitta's house. The blame falls on Ezio Zernar, the investigator who had "found" the cuts in the first place. Zernar is sentenced to two years for forging evidence, and Zornitta is officially dismissed as a suspect in 2009.
I don't know but I'm having a feeling that a thread about the Italian Unabomber may had been posted here. Can someone confirm if there's already a post on him? If yes, I'm deleting this thread.
The reason I could not write more about him is that my Internet is a bit crappy at the moment, so I decided to put the basic details here. But, if you want a complete write-up, check the Reddit link I posted above.
Regards.
