Park City ? In what’s described as a “very generic, very laid-back” letter to the congregation of Christ Lutheran Church, Dennis Rader thanks the church members for their support and asks for their continued prayers for him and his family, the church’s pastor said Friday.

Rader, 60, who is accused of being the BTK serial killer, has been in custody since he was arrested Feb. 25. He is charged with 10 counts of first-degree murder for slayings that occurred from 1974 to 1991.

The Rev. Michael Clark, who visits Rader in the Sedgwick County jail a couple of times a week, said the letter had been posted for about a month before he took it down Friday.

“I posted it on the bulletin board where we have all the greetings, all the letters, all the expressions of concern for members of the congregation,” Clark said. “I mentioned in a worship service that I had copies posted on the bulletin board.

“It’s a very generic, very laid-back letter expressing his appreciation,” the pastor said.

BTK — a self-coined nickname that stands for “Bind, Torture, Kill” — stoked fears throughout the 1970s in Wichita.

Rader, a former city codes enforcement supervisor in Park City, has been a member of the church for 30 years, where he has served as an usher and president of the church council.

Clark said his congregation’s feelings for Rader since his arrest have been mixed, though he said the ordeal has brought some families who had been inactive back to the church.

Earlier this week, Rader waived his right to a preliminary hearing, which means prosecutors will not have to publicly reveal any of their case against him until trial. He is expected to enter a plea at his arraignment, set for May 3.
