CARBONDALE, Ill. (AP) — The father of a 21-year-old Carbondale woman killed in a suspicious shooting has filed a notice of appeal on the dismissal of a wrongful death lawsuit against Richie Minton.

Larry Young’s attorney had reportedly been working on the appeal before a determination was made about Illinois State Police improperly withholding records to Young.

The Illinois Attorney General’s Office determined that State Police “improperly withheld” public records sought by Larry Young.

His daughter Molly Young died in March 2012 at the apartment of her ex-boyfriend, a Carbondale police dispatcher Richie Minton. Her case remains open after the state’s prosecutor couldn’t determine whether a single gunshot to her head was an accident, suicide or homicide.

Larry Young appealed to the top Illinois prosecutor’s Public Access Bureau after the State Police denied his January 2014 records request. The law enforcement agency said that it had already provided Young with all the records he was legally entitled to.

The bureau ruled last week that Illinois State Police violated the Freedom of Information Act and ordered it to release additional documents.
