BOLINGBROOK - A lawyer for a former police officer suspected in his wife's disappearance says the man has re-ceived a death threat.

Lawyer Joel Brodsky said he's worried about his client's safety after racially tinged, threatening note appeared in Drew Peterson's suburban Chicago mailbox over the weekend.

The 54-year-old is a suspect in the disappearance of his wife, Stacy Peterson, who vanished in late October.

Authorities have called the case a possible homicide, although Drew Peterson hasn't been charged with any crime.

Meanwhile, investigators are also re-examining the death of Peterson's third-wife, Kathleen Savio.
