"In the data surrounding the threatening traffic, they found traffic containing Ardolf’s name and Comcast account."

What do you suppose this means? Did his decide to check his personal email while on his neighbor's wifi?

My guess is that maybe he was bright enough to crack the WEP but not bright enough to send the e-mail through the victim's ISP's SMTP relay, but instead sent it through his own (Comcast's), possibly authenticated with his own username and password, if Comcast does user authentication for SMTP instead of just trusting all of their customer subnets blanketly.

Maybe his e-mail client decided to check for new mail while he was still connected to his neighbour's WiFi?
