The founder and former CEO of a local high-tech company was sentenced Friday to 4 1/2 years in state prison on felony drunken-driving charges.

John M. Bourque, founder of armor-plate maker Bourque Industries Inc., was convicted last month on two felony drunken-driving charges stemming from an arrest in 2009.

After the conviction, the company announced an interim CEO to replace Bourque. The company said Bourque steadfastly maintained his innocence and intended to appeal.

Bourque, 49, was arrested on suspicion of aggravated drunken driving on Sept. 23, 2009, after being pulled over for speeding in Tucson, court documents show. His trial was delayed several times after Bourque switched attorneys.

As a repeat offender, Bourque could have been sentenced to up to seven years. He spent more than three years in state prison for aggravated driving under the influence in 2002, state Department of Corrections records show.

He has been in custody since the verdict, pending his sentencing Friday by Pima County Superior Court Judge Richard D. Nichols. Other details of his sentencing were not immediately available.

According to a presentence report prepared for the judge, Bourque had faced a minimum of four months in prison on each of the two counts, fines and assessments totaling $4,000 and mandatory alcohol and drug screening and treatment.

Bourque Industries has developed tough, lightweight armor plate and other products based on a patented aluminum alloy, including a nationally certified body-armor plate.

Following Bourque's conviction, the company named Sean Floyd as the company's interim CEO and added two directors. Floyd joined Bourque in January 2012 as executive vice president.
