Gathering crime scene evidence and the science of catching criminals is just part of the focus of a free presentation coming to the Smoky Hill Museum on Thursday.

Former Director of the Kansas Bureau of Investigation Larry Welch is coming back to Salina’s Smoky Hill Museum to deliver another look at his book, Beyond Cold Blood: The KBI from Ma Barker to BTK.

Welch joined in on the KSAL Morning News Wednesday and said the murders around Wichita involving Dennis Rader were not initially probed by the KBI.

“At first the KBI really wasn’t involved in BTK, it was just considered a local homicide,” he said.

“It was the quality of the crime scene work by those detectives that worked the Otero murder case and the preservation of the evidence from that scene that later allowed the Otero murders to be connected to BTK.”

Welch, the author of Beyond Cold Blood: The KBI from Ma Barker to the BTK, will be presenting part two of a behind the scenes look at the KBI during a presentation at the Smoky Hill Museum Thursday, November 3rd from 5:30pm to 6:30pm.

The museum notes that the nature of the material may not be appropriate for junior high aged students and younger.
