(AP) Twenty-eight registered sex offenders in Michigan who are on probation or parole recently had profiles on MySpace.com, a social networking Web site, the state attorney general's office said Thursday.

Four of the sex offenders have terms of supervision prohibiting their use of a computer or the Internet. Altogether, about 200 individuals whose names match the Michigan sex offender registry had MySpace profiles, Attorney General Mike Cox said.

MySpace used ZIP codes and addresses to determine that they are registered sex offenders, Cox spokesman Matt Frendewey said.

Cox's office, along with many other states, filed subpoenas for the list after MySpace agreed to share information about registered sex offenders it had identified and removed from the site.

His office filed a motion Thursday against one person on the list, Edward Mitchell Mulak of Ferndale, urging a judge to find him in violation of terms of his probation. Cox's office prosecuted Mulak for possessing child pornography in 2006.

Three other sex offenders on probation or parole were referred to the Michigan Department of Corrections, Frendewey said. Frendewey estimated that 70 of the 196 MySpace users on the state sex offender registry are considered "child predators" — those convicted of sex offenses with minors.

MySpace is one of the most popular online social networking sites. It has more than 185 million individual profiles, similar to a personal Web page.

Cox said his office's findings should remind parents to monitor their children's Internet activities.
