OREGON, Ill. (AP) – Ogle County officials are at odds with a family member over who should supervise the exhumation of the remains of a teenager who was killed near this northern Illinois town 56 years ago.

Warren Reed was granted a request from an Ogle County court in April to exhume the remains of his sister, Mary Jane Reed, whose body was found along a rural road in June 1948. Former Oregon Mayor Michael Arians, who has taken a personal interest in the unsolved slaying, also petitioned for the exhumation in hope of finding clues.

But their plans to exhume the body in August are on hold after Ogle County State’s Attorney Deborah Ellis filed a motion to intervene on May 26 on behalf of the county sheriff and coroner. Ellis said the case is an open murder investigation and the county has jurisdiction.

“The exhumation could yield clues that could contribute to solving the crime,” Ellis said.

Attorneys for both sides are expected in court June 29 to try to reach an agreement. Judge Stephen Pemberton, who granted Reed’s exhumation request in April, could ask for testimony if the two sides can’t settle the matter, Ellis said.

Mary Jane Reed was 17 when she and her boyfriend, Stanley Skridla, 28, were shot to death on the outskirts of Oregon.

about 100 miles west of Chicago. Records show the couple were parked on a country road when someone pulled Skridla from the car and shot him five times. His body was found the next morning.

The woman’s body was found a few days later, 2 miles away, with a single bullet to the head.

Reed and Arians had planned to hire a private forensics investigator to examine the remains. The county’s petition asks that the two men pay for the exhumation while the county conducts the post-mortem exam. The entire process is estimated to cost more than $10,000.

The county petition also asks that the exam results not be released because they could jeopardize the investigation.

Arians became interested in the case when acquaintances of Reed’s family asked that he look into it after he was elected mayor in 1999. Since then he started the Mary Jane Reed Foundation and has memorialized the woman with a mannequin on display in a restaurant he owns in town.
