Scott Roeder, the man convicted of killing Dr. George Tiller, has now been disciplined for intimidating those who have reopened Tiller’s abortion clinic.

According to a Reuters report, Roeder has been punished with 45 days of solitary confinement for comments he made in a telephone interview back in April. A prison hearing determined that his statements could intimidate members of the now-renamed South Wind Women’s Center. According to the Kansas Department of Corrections, he will spend 23 hours per day in his cell for 45 days, and have “reduced privileges” for 60 days.

Roeder’s interview was with David Leach, a well-known anti-abortion activist based in Iowa.

“To walk in there and reopen a clinic, a murder mill where a man was stopped, is almost like putting a target on your back saying, ‘Well, let’s see if you can shoot me,'” said Roeder.

Roeder was convicted in 2010 for the murder of Tiller, one the only doctors in the U.S. who performed late-term abortions. Roeder shot Tiller in the head at point blank range while Tiller was attending a worship service at a Lutheran Church in Wichita, Kansas. He was sentenced to life in prison without the possibility of parole for 50 years.
