McNamara had reportedly pleaded guilty to both charges, admitting that he had been drinking when he hit the left rear of a Pontiac G6 in which the student was a passenger. Authorities said that McNamara was driving 152 miles per hour just prior to the accident and had a blood alcohol level of .171, more than twice the legal limit.
The family of the student, who graduated from the university posthumously with honors in December, described her as a youth minister, teacher and resident mother for her sorority.
The student's parents and the Platte County prosecutor testified to McNamara's previous convictions including a number of speeding tickets and a prior DWI in 2005, according to the news source.
