In Pursuit with John Walsh (10 p.m., Investigation Discovery) - ID partners with the National Center for Missing and Exploited Children in a new John Walsh-hosted series that hopes to track down suspects in open violent crime cases and help bring missing children home. Each week Walsh will present violent crimes, with his son Callahan Walsh working with local authorities and leading operations on the ground. Episodes will also feature two missing children, providing age-progression photos and descriptions. The first episode focuses on former Oklahoma police officer Luis Frias who stabbed his ex-wife 41 times in front of her children before vanishing, and 69-year-old wife strangler Harold Butch Knight of Michigan.
