WICHITA, Kan., April 17 (UPI) -- Prosecutors in Kansas are expected to reveal the evidence connecting a devout Lutheran and family man with the BTK killings in Wichita at a preliminary hearing this week.

The hearing begins Tuesday in Sedgwick County District Court and could last a week as prosecutors go through 10 murders carried out between 1974 and 1986, USA Today reports.

Dennis Rader, a church and Boy Scout leader and compliance control officer in the Wichita suburb of Park City, was arrested in February. He faces life in prison if convicted, since Kansas had no legal death penalty at the time of the killings.

Rader's lawyer told USA Today that his client plans to plead innocent.

The killer gave himself the name "BTK" for "bind, torture, kill" in communications he sent the Wichita Eagle. After years of silence, he sent the newspaper a copy of the last victim's driver's license and snapshots of her body.
