How odd that Perugia LE is up and ready to investigate Aviello's claim that he committed perjury in return for a bribe by the Sollecitos. We never saw that much energy when it came to investigating Aviello's original lie that his brother killed MK by mistakes and hid the keys, etc.
How about ... prosecutors knew the original lie was a lie, and as long as it wasn't presented in court it wasn't worth wasting the time. Now that the liar claims he was promised something by the lawyers or families of Knox and Sollecito in exchange for false testimony and he lied under oath in court, it's a bit of a problem for the lovebirds.
We knew when the pair paraded the lying prisoners through the courtroom that the lovebirds looked desperate. Now we see how desperate they are. I wonder who else has been offered money in exchange for favorable testimony.
