OK. Note that this is definitely speculation. The book does not say specifically that Rudy has anything specific, but the author, Nina Burleigh, spent more time on the background of each of the key players involved in the case than other authors, vs. spending a lot of time on the court case.
Some of the facts in the book about Rudy are:
* He had an extremely difficult early childhood. He was separated from his mother at a very early age, and brought to Italy from The Ivory Coast by his father. Although his mother was still alive and had another family in the IC, he never saw her again after a very young age
* His father would go to work and leave Rudy alone in the house to take care of himself at a very young age (like 5), and sometimes not come home. He would also lock Rudy in the bathroom or other small space and leave
* There was mention that Rudy told someone (can't recall who) about being whipped and having a stick smashed over his head when he disobeyed
* Rudy's dad was often not around, and went back to the IC a time or two without him. Rudy was taken in by some kind Italian women who would make sure he got to school and had food to eat
* At one point, as a teenager, Rudy was basically "adopted" by this wealthy family, and for a year or two had a great life, from the standpoint of having whatever he wanted materially. But for some reason, he threw that all away, acting out in ways that ended up in that family giving up on him.
* After high school years, Rudy had one friend in particular that he liked to hang out with, and Rudy would ask to come over to this guy's apartment to stay overnight, because Rudy did not like to stay alone at his own place. But this guy had to ask Rudy not to stay over anymore, because Rudy would wake up in the middle of the night and act out strange scenes, like he pretended he was teaching a school class, and was lecturing the students on some subject, except that in reality, Rudy was asleep. This guy and another friend of his got creeped out by Rudy doing this, and they asked him not to come over any more.
* There is also mention of some other burglaries, including one where a woman who was very close to Rudy had a bunch of her personal stuff stolen, and it was never solved. Of course, there is no evidence Rudy was involved, but the MO was similar to later burglaries he committed and one of the things that was missing, a woman's gold watch, is similar to one Rudy was caught with at that nursery school in Milan. Except the cops never checked the watch, so it may or may not be the same one.
Now, none of this indicates why someone would commit a murder, but it does indicate evidence of a person who might have some mental or emotional problems that have never been properly diagnosed. To most in Perugia, he probably appeared to be just a regular guy, and maybe he was, before the murder, but it seems that, if this info is true, Rudy may have had some very real emotional issues. Issues that might lead someone to act very irrationally when triggered by something. He might not deal well with rejection -- but who knows.
None of the above is proof of anything, not compared to his DNA and prints in the murder room.
Thanks a lot for this breakdown, Dougm. Greatly appreciate your time.
I will seek out a copy of Fatal Gift.
