Killer Or Cover-Up Murder Trial

The State was not finished breaking down the testing done on Karen Read when it came to how much alcohol was in her system. Police wanted to know if Karen Read was under the influence of alcohol when she was driving her SUV the night they say she hit John O'Keefe, her boyfriend. He ended up unconscious in the snow for hours. So, investigators used a type of testing to get an estimate of how much alcohol may have been in her system hours before an official blood test was done.
