Though the killer did not rape his victims, semen was allegedly found at crime scenes and preserved. Various news outlets are reporting that, contrary to earlier assertions that Rader’s daughter turned him in, it now appears that a she was merely the source for a DNA match between evidence and Rader.

The Associated Press and other outlets are reporting that Rader has confessed to six of the murders, police and prosecutors think Dennis Rader may be responsible for up to 13 murders, including one that occurred after after Kansas reinstated the death penalty.
