Hi RWVBWL
We seem to be in a minority of 2 here

Until the DNA investigations on Aviello and Florio are completed I am not convinced that Rudy was the murderer.
Also as you say not enough damage in Meredith's room for a lone attacker.
Hi once more Magister,
I agree, most people do not give Aviello's testimony much weight, since he is in prison and has, I believe, said things of this nature before. Personally, I know lots of guys who've been imprisoned, heck they are the trouble makers and know what's really going on down on the streets. Where better to get more information about a murder?
Anyways, getting caught up on the overnight JREF posts, I read a short while ago that you asked about this:
I am cross-posting here in case anyone wishes to join in discussion, if that is ok, MOD's...
Post 79: Alternate motive: Possibly a drug dealer was picking up his supply in front of the house and thought that Meredith was a police informant.
"Perugia may boast stunning views across the Umbrian hills and a world-class jazz festival held in frescoed palazzi, but it also has the highest number of overdose deaths per capita in Italy, as addicts move to be where the wholesalers are. North African dealers lurk on corners in the city centre and Nigerians control the suburbs, all under the watchful eye of the Calabrian 'Ndrangheta mafia."

"I was in the bathroom when it happened. One thing is certain, Amanda wasn't there."
"I fought with a man when I came out. She was not there." Rudy Guede's taped conversation while on the run in Germay.
Rudy Guede mentions in his German diary that when he arrived at the house that he saw a white car with lights on and a drug dealer that he recognized from Garibaldi street. We have heard from other students that the park near the house was a known area of drug dealing and drug use.
From Rudy's German diary:
"Then I headed for Meredith's house. With all the running around I did, I think it would have been around 8:30 p.m. Because we were supposed to see each other at that time, even though I didn't have a watch I tried to arrive on time, because I usually arrive late. As I arrived in front of the house, I noticed a white car with headlights on, and a Drug-Dealer I often saw on Garibaldi Avenue, but I
didn't make much of this and I went into the yard. I knocked on the door, but no one answered. I went downstairs to the guy's place but no one was there either. So then, I waited in the yard."
Whoever controls the supply of drugs controls the entire drug operation. Small time dealers are supplied with only a limited amount of drugs. They must make contact with their supplier to receive product to sell and then the supplier picks up the money. Hekuran Kokomani was caught with 8 grams of cocaine in February 2009. Who is he? A small time dealer or a supplier? Or as he says innocent because the drugs were not his?
8:01 p.m. Hekuran Kokomani's mobile phone record shows that he entered the area of the cottage at this time, where it had earlier that day placed him in the Assisi locality.
It is not a stretch to believe that possibly Rudy saw a drug dealer making a connection with his supplier right there in front of the house. At that same time, Meredith was arriving at the house from having dinner with her friends. We also know that her cellphone shows that she tried to call home at that very time.
8:56pm (20:56) (Meredith’s house) Meredith’s cell phone calls her mother but call is cut off before it is finished.
If Meredith was making a call home outside with her cellphone at the same time that a drug dealer was picking up his supply in the area of her house, did this drug dealer believe that Meredith was a police informant? Witnessing drug deals have been the reason that others have been murdered by drug gangs.

Interesting stuff to consider...

Magister, you beat me to it!
