The CEO of a local high-tech company was convicted Wednesday on felony drunken-driving charges stemming from an arrest in 2009.

John M. Bourque, CEO of armor-plate maker Bourque Industries Inc., was convicted by a jury of aggravated driving under the influence with a revoked or suspended license, and aggravated DUI with a blood-alcohol level of 0.08 percent or more, Pima County Superior Court officials said.

He was taken into custody after the verdict, pending a sentencing hearing before Judge Richard D. Nichols in March.

Bourque may face an extended sentence of more than seven years as a repeat offender. He spent more than three years in state prison for aggravated DUI in 2002, state Department of Corrections records show.

Aggravated DUI, a felony, carries a sentence of up to 3 1/2 years, fines of up to $150,000 plus surcharges and license revocation for at least three years. But felony defendants with prior felony convictions can face up to 7 1/2 years in prison.

Bourque was arrested on suspicion of aggravated drunken driving on Sept. 23, 2009, after being pulled over for speeding in Tucson, court documents show.

Bourque Industries has developed tough, lightweight armor plate and other products based on a patented aluminum alloy, including a nationally certified body armor plate that has gained some national media attention.

This week, the company announced a $252,000 purchase order from a Chinese company for electrical heat-sink materials. But sales have been sporadic, and Bourque's over-the-counter stock lost much of its value in 2011, after the company wrote down the value of most of its assets after concluding that a precious-metals refining business was was not commercially viable.

Bourque Industries officials could not be reached for comment.
