JACKSONVILLE, Fla. (AP) - Attorneys for a Jacksonville man accused of fatally stabbing a Chicago Bears fan say he suffers from post-traumatic stress disorder.
    
They told Circuit Judge Suzanne Bass on Thursday that the disorder is one of the factors that led 28-year-old Matthew Reid Hinson to kill William "Chris" Pettry before a Jaguars-Bears game in 2012.
    
Assistant Public Defender Kate Bedell says Hinson also suffers from alcohol abuse.
    
The Florida Times-Union (http://bit.ly/112N6mk ) reports prosecutors are skeptical and asked the judge if they can have a doctor examine Hinson.
    
Hinson pleaded guilty in May to second-degree murder and faces 20 years to life in prison. He could get a lesser sentence if the judge allows alcohol abuse and PTSD as mitigating factors in Pettry's stabbing.
    
Pettry was visiting from Lake Villa, Ill., near Chicago.
