San Luis Obispo, CA -- .A prosecutor says a woman charged with murder was driving recklessly while high on methamphetamines when she struck and killed a California Highway Patrol officer standing alongside his squad car near Paso Robles.  

Jurors begin a first full day of deliberations Thursday in the trial of 23-year-old Kaylee Ann Weisenberg, who is charged with second-degree murder and gross vehicular manslaughter while intoxicated for last year's crash that killed CHP Officer Brett Oswald.  The 47-year-old officer was waiting for a tow truck when Weisenberg's Toyota Corolla struck him.  

Prosecutor Lee Cunningham told jurors during his closing on Wednesday that Weisenberg's blood tests showed a methamphetamine level double the amount for someone under the influence.
