PHOENIX -- Authorities say a 3-year-old boy is dead after his stroller was struck by a vehicle in west Phoenix.
Phoenix police say the incident occurred about 1 p.m. Thursday on a private access-road at the Desert Sky Esplanade near 75th Avenue and McDowell Road.
They say the child was in a stroller being pushed by his babysitter, who was slightly injured.
Police say the babysitter was leaving the shopping center when she attempted to cross a private road maintained by the property's owners.
