RAPID CITY, S.D. (WKOW) -- Authorities in South Dakota say a woman accused of driving drunk has blood alcohol content of .708, a possible state record, and double the amount that is potentially lethal.
Police found 45-year-old Marguerite Engle passed out in a stolen delivery van Dec. 1. She is accused of driving under the influence.
Meade County State's Attorney Jesse Sondreal said the highest blood alcohol content he is aware of in the past is .56. The state's legal limit is .08. Engle's B.A.C. was almost 9 times the legal limit.
Authorities say Engle missed an initial court hearing Dec. 15. Police later found her in another stolen vehicle, and they say she had been drinking.
Engle is being held on two counts of driving under the influence.
Experts say potentially fatal alcohol poisoning happens when the blood alcohol content reaches .35 to .40.
