The FBI wants access to the Skype records of a local terror suspect.
Investigators say Alexander Ciccolo may have talked with someone interested in helping him in a terror plot.
The 24-year-old was arrested last year after his father, a Boston Police captain, alerted the FBI to his son's desire to fight with ISIS.
Investigators say he was building molotov cocktails and was planning to attack a local college.
The FBI is asking Microsoft to turn over the Skype call log and written messages on Ciccolo's account, as well as his password.
