Springfield Mayor Timothy Davlin's death has been ruled a suicide.
A Sangamon County inquest Thursday determined the 53-year-old Democrat died of a close-contact bullet wound to the heart in a vehicle parked at his home Dec. 14.
Investigators say they found no note from Davlin. They say there were no signs of foul play and no drugs or alcohol in his body.
Davlin apparently called 911 from a cordless landline phone in his car but hung up.
