According to court records, McQuinn's blood alcohol content was .095 hours after she was arrested. A second test an hour later showed a blood alcohol content of .071.
The accident killed Charles Cooper, 72. The Missouri State Highway Patrol said Cooper's utility vehicle was hit by a McQuinn's car when he drove onto Highway 69 south of Cameron around 5 p.m.
A trooper said the UTV went into a spin and ejected Cooper. He was taken to Cameron Regional Medical Center, but did not survive.
McQuinn was not injured.
According to court documents, McQuinn was convicted of DWI in Clinton County in 2006.
