Council Bluffs Police says a 63-year old woman was struck and killed early this morning while she crossed the street on her daily walk. Council Bluffs Police Sgt. Bob Sellers said Mae Zhang, of Council Bluffs was crossing the street from the north to the south when she was hit by an eastbound car driven by 21-year old Sarah Harris, also of Council Bluffs.  Zhang died at the scene. The accident happened at around 7:15-a.m. in a neighborhood just east of the Mall of the Bluffs. Sgt. Sellers says sunglare was likely a factor in the accident. Witnesses say the glare is most prominent when motorists traverse the hill in those hours just after sunrise.
