Mildred Wallace, 65, was killed in her Cape Girardeau, Missouri, home on June 21, 1982. An intruder shot, sexually assaulted, and strangled her; investigators found the attacker’s blood, a bootlace used as a garrote, a palm print, and bits of skin under her fingernails indicating she fought back. The case remained a cold homicide for years as a series of similar attacks terrorized the region, attributed to a man later nicknamed the boogeyman in the blue bandana who reportedly stalked victims and broke into homes.

Advances in forensic testing led to a breakthrough in 2007 when DNA from the crime scene linked Timothy Wayne Krajcir to Wallace’s murder. Krajcir, already behind bars for other offenses, was charged in this and other killings and later pleaded guilty to multiple murders in Cape Girardeau.

Did anyone in Cape Girardeau at the time remember suspicious activity or a person fitting the description in the weeks before June 21, 1982?
