A jury convicted a man Monday of arson in fire that injured seven Detroit firefighters last summer, according to The Detroit News.
Calvin Raymond Jones, 41, faces up to 40 years in prison after was found guilty of helping co-defendant Samson Wright start the Aug. 13 fire at a Metro PCS store on the city's east side.
His sentencing is slated for Oct. 11.
Wright pleaded guilty in May and will be sentenced on Aug. 16.
Three of the injured firefighters were forced to retire including Brendan Milewski, who was paralyzed from the waist down.
"While this conviction will not heal the firefighters' serious and permanent injuries, we hope that it will deter others from committing arson in the future," U.S. Attorney Barbara McQuade said in a prepared statement.
