A Siouxland man has been convicted of supplying alcohol to a teenage girl who later died in traffic
Seventeen-year-old Mary Hughes, of Salix, died Feb. 21 in a collision as she was driving on Interstate 29 south of Sioux City.
Authorities later said her blood alcohol content was nearly three times the legal limit.
The Iowa State Patrol says it learned that the alcohol Hughes drank before her death had been supplied by 26-year-old Robin Armfield, of Hornick.
Armfield was found guilty on Thursday of supplying alcohol to a minor, a serious misdemeanor.
He faces up to a year in jail.
