Musson was initially arrested by the Shorewood Police Department on a manufacture/delivery of a narcotic charge on June 29, the day after he drove an unconscious Rebecca R. Sova to Presence St. Joseph Medical Center in Joliet for medical treatment, the newspaper reported.
He has been held at the Will County jail since that day, unable to make the $999,999 bond set by a judge.
A coroner's investigation later determined that Sova died on July 2 of opiate intoxication, leading to the higher-level charge Musson now faces, the story said.
Although Shorewood police told the paper that Musson was a heroin user, the summer arrest marks his first arrest on a drug-related charge.
According to Will County circuit clerk and jail records, Musson has been arrested dozens of times since 1997, including three times for driving under the influence of alcohol, twice for aggravated battery and more than a dozen times for driving with a revoked or suspended license.
Musson has served three prison terms -- two years for aggravated battery, three years for driving with a revoked/suspended license for DUI and three years for aiding/abetting/possessing/selling a stolen vehicle, according to Illinois Department of Corrections records. He was on parole for the agg battery sentence when arrested for his role in Sova's drug overdose, records show.
