Gov. Mike Beebe has ordered Arkansas flags to be flown at half-staff on Saturday in honor of a state deputy who was killed while driving a hitchhiker to a homeless shelter on Monday.

Lafayette County Chief Deputy Pete Richardson was taking 30-year-old Michael Lee Ackart to Texarkana when Ackhart grabbed the steering wheel of the vehicle, causing the deadly crash. 

The Arkansas Democrat-Gazette reports that Ackart, of Tulsa, Okla., has been charged with second-degree murder. 

Beebe says Richardson exemplified the finest traits of Arkansas's law-enforcement community: loyalty, bravery and selfless devotion to duty.
