Roeder apparently kept track of the state prosecution against Tiller through a senior member of Operation Rescue, the anti-abortion organization.

At the time of Roeder’s arrest Sunday afternoon along Interstate 35 in Johnson County, a television station captured the vehicle on video. There on the dashboard was a note that read “Cheryl” and “Op Rescue” with a phone number.

Cheryl Sullenger, senior policy adviser for Operation Rescue out of Wichita, said Tuesday that she has spoken to Roeder in the past, but she said he would initiate the contact. She said she hasn’t had any recent contact with him.

Sullenger served about two years in prison after pleading guilty to conspiring to bomb an abortion clinic in California in 1988. She has since renounced violent action.
