A former police sergeant suspected in the disappearance of his wife was stopped for speeding early Saturday morning on the way to meet a young woman.

Drew Peterson said he was stopped at 2:30 a.m. on Saturday in Naperville, Ill., for speeding on his way to help a 22-year-old woman in Chicago's western suburbs, the Sun-Times reports.

He didn't get a ticket and police, instead, gave him a warning.

Peterson is suspected in the October 2007 disappearance of his wife, Stacy, but he hasn't been charged.

The former Bolingbrook police sergeant said he was pulled over as he drove to pick up the woman he describes as a friend after she called him for a ride.

Peterson's attorney said the woman works at a tanning salon he sometimes visits.

"That's just the type of guy he is," attorney Joel Brodsky told the paper.
