Let's examine Guede's timeline after the murder/rape of Meredith to understand when bugging his phone might be of interest:
Nov. 1, 2007 about 9:30 pm Murder/rape; later that night, Guede goes to a disco
Nov. 3 ? Guede goes to Germany
Nov. 16 Police visit apartment of Guede with Giacomo Benedetti *
Nov. 19 Police record 3-hour Skype conversation between Guede and Benedetti *
Nov. 20 Guede arrested on a train in Mainz, Germany after travel w/o ticket *
Nov. 20 Forensic police collect items from Guede's apartment *
Dec. 6 Guede returns to Italy. Vaginal swab DNA matches his DNA *
* Information from MMK website
So police could have bugged Guede's apartment from Nov. 16, 2007 until, say Dec. 6, when he would have been held in Italian police custody.
