ST. PAUL, Minn. (AP) - A Minnesota man has pleaded guilty to hacking into his neighbor's Internet system to send a threatening e-mail to Vice President Joe Biden.

The U.S. Attorney's office says 45-year-old Barry Ardolf of Blaine stopped his trial to plead guilty.

Ardolf also pleaded guilty to e-mailing child pornography.

In his plea agreement, Ardolf admitted hacking into his neighbor's wireless connection and creating multiple e-mail accounts in his neighbor's name. Ardolf then used one of those accounts to e-mail Biden's office in May 2009. The message said, "I'm assigning myself to be judge, jury and executioner."

Ardolf also admitted posing as his neighbor and sending child porn.

Court documents say neighbors reported Ardolf for inappropriately touching one of their children. Prosecutors say he retaliated with the e-mails.
He'll be sentenced later.
