The driver of an SUV that hit and killed highway patrolman Jay Sampietro last month has been charged with manslaughter. The charge says Wendye Chesher failed to slow slow down, failed to yield to an emergency vehicle, and failed to follow Sampietro’s directions. The Webster County Prosecutor says Chesher was running about 60 miles an hour when she swerved into the median and hit Sampietro. He was the first of two troopers killed recently in southern Missouri. The Texas County Proscutor is waiting for a full crash report before he decides whether to file a charge against the motorist who hit and killed Trooper Kevin Floyd, who was killed during a traffic stop last week.
