Letter claims missing mom seen in Ky.

BOLINGBROOK, Ill., Jan. 7 (UPI) -- An anonymous letter writer claimed to have seen missing suburban Chicago mom Stacy Peterson with a man in a Kentucky mall parking lot after her disappearance.

The letter was mailed to Peterson's husband, former police Sgt. Drew Peterson of Bolingbrook, Ill., with a Dec. 29 postmark from Cincinnati, the Joliet Herald-News said.

The writer said the woman at the mall in mid-November appeared to have locked keys in her vehicle. He watched, then approached her after the man went into the mall, and showed her a newspaper picture of Stacy Peterson.

The woman told him to mind his own business. Later she said, "I just want to be left alone, please," the letter said, and she fled through the parking lot. The man wrote he didn't want to share his name fearing media coverage.

Drew Peterson has been named a suspect in the Oct. 28 disappearance of his wife.

Stacy's Peterson's family dismissed the letter.

"Most tips that come in of any value have names attached to them," Pam Bosco, spokeswoman for the missing woman's family, told the paper.

Police also have reopened the investigation of the death of one of Peterson's previous wives, Kathleen Savio.
