Google News search brings up other articles from the 13th (the day your links were posted) through the present ranging on the fact that the judge ordered an examination and his motivations for his actions.
How precisely is that a cover up? I really wouldn't trust a student's awareness on a lot of things. I tried to keep informed in college but I wasn't always successful, particularly on more local issues, as this was. (Is the Wayne University medical school on the same campus as the rest of the University?)
It appears that the sites you posted found it in their best interest to claim that no other sites were covering this issue.
Plus those sites are very... whats the word... fear-centric. This guy claims to be part of Hezbollah so they jump to the possible conclusion that Hezbollah ordered the attack instead of the same thing that happened previously with other "would be terrorists." They find a name, a group, that they like, but the group doesn't know who the hell they are.
