Lawrence Bittaker and Roy Norris, known as the Toolbox Killers, were convicted of abducting, torturing, raping and killing five young women in the late 1970s in Los Angeles, California. The killers both died in San Quentin prison- but not before forensic psychology practitioner and private investigator Laura Brand could interview them. Her interviews have revealed details never before known to the public, and her goal is to recover the remains of their victims whose remains were never recovered so they can be returned to their families.


Our team at Redgrave Research is honored to assist Laura in her research. We helped with researching the families of the killers, as sometimes the genealogy of a person can help give insight to a person’s psychology. We also have helped with other research related to missing persons who could have crossed paths with these perpetrators.

Tune in to Peacock on the 23rd or the Oxygen channel on October 3rd to see the premiere of “The Toolbox Killer”, featuring Laura Brand, the “Siren of San Quentin”, and her work to bring peace to the victims of these notorious serial killers.
