(AP)- Prison officials are accusing the convicted killer of abortion provider George Tiller with trying to intimidate the woman who reopened his Wichita clinic.

The Kansas Department of Corrections said Tuesday it filed an administrative charge against Scott Roeder under a prison regulation which prohibits threatening or intimidating anyone. The 55-year-old Roeder is serving a life sentence at the prison in Lansing for Tiller’s 2009 murder at the physician’s church.

Prison spokesman Jeremy Barclay says an administrative hearing will be scheduled to determine whether Roeder is guilty. Such offenses can result in segregation, loss of privileges and extra work.

The charge stems from a recorded phone call an abortion opponent posted on YouTube in which Roeder says reopening the clinic is almost like putting a target on the clinic director’s back.
