A man who pleaded guilty to sending an e-mail threat to two Virginia Tech alumni on the eve of the first anniversary of the university's mass shooting has been released from jail and ordered to undergo psychiatric treatment.

Johnmarlo Balasta Napa of Las Vegas tearfully apologized Monday in U.S. District Court in Roanoke for hurting the two women.

Judge James Turk sentenced him to the time served, which is nearly 15 months.

Napa, who has been diagnosed with paranoid schizophrenia, has said he sent the e-mails to draw attention to violent Internet postings.

The e-mail recipients had complained that Seung-Hui Cho had stalked them. Cho was the student gunman who killed 32 people and himself on Virginia Tech's campus in 2007.
