Winston Riley Claims He Was Sleepwalking When Robbing A Woman At Knifepoint

NEW LONDON, Conn. - A Connecticut man accused of attempting to rob a woman at knifepoint in an elevator at the Mohegan Sun casino says he was sleepwalking at the time.

The Norwich Bulletin reports Winston Riley told his attorney he was awakened on March 18 by the woman when she ran away in confusion and fright.

Attorney Nicholas D'Amato says he's confirmed with Riley's family that the 27-year-old has had a problem with sleepwalking since he was a child. The lawyer says he's in the early stages of gathering medical records in his attempt to convince prosecutors they should take the claim seriously.

Riley's bond was lowered Wednesday to $85,000 from $100,000. He is due back in court July 17.
