lights and sirens

A Sierra Vista woman was fatally struck by a vehicle Wednesday while crossing State Route 90 near Rainbow Way in Sierra Vista, officials say.

Sharron Pottier, 67, was struck around 10:30 p.m. while crossing the highway more than 50 feet east of a HAWK crosswalk, according to Sgt. Brian Sebastian, a Sierra Vista Police Department spokesman. 

Witnesses told police the light, which turns solid red followed by flashing red, wasn't activated at the time of the collision.

The driver who struck Pottier remained at the scene and cooperated with investigators, Sebastian said. The driver submitted breath and blood samples. Officials are doing laboratory testing on both the driver and Pottier. A press release says no citations were issued and excessive speed was not a factor in the collision.
