A brother of the man suspected of fatally shooting abortion doctor George Tiller told a Kansas newspaper that the family never foresaw him capable of killing.

Scott Roeder was in jail Monday while investigators sought to learn more about his background. He has not been charged in Tiller's slaying at a Wichita church Sunday.

David Roeder said in a statement to The Topeka Capital-Journal that the family is "shocked, horrified and filled with sadness at the death of Dr. Tiller" and the possible involvement of Roeder.

David Roeder said Scott is "kind and loving," but suffered from mental illness at times in his life.

David Roeder says, "None of us ever saw Scott as a person capable of or willing to take another person's life."
