London:
A 55-year-old US woman sleepwalked into a lake and drowned, a media report said on Thursday.
Charlene Ferrero left her Oaklyn, New Jersey apartment on Saturday night and fell from a train trestle into a lake, and drowned - all while she was asleep.
Her body was pulled out from Newton Lake by search crews Monday night, Daily Mail reported.
Ferrero worked as a waitress at the Starview Diner in Somerdale, New Jersey. Her co-workers are just as baffled as her friends over her tragic end.
The autopsy ruled Ferrero's death an accident, though it will take several weeks for results of the toxicology report.
Medications such as sleep aid Ambien have been known to cause sleepwalking.
