Theresa Jimmie Francine Knorr (née Cross; born March 14, 1946) is an American woman convicted of torturing and murdering two of her six children while using the others to facilitate and cover up her crimes. She was acquitted of murdering her first husband and was also considered a suspect in the unsolved murder of her sister. She is currently serving two consecutive life sentences at the California Institution for Women in Chino, California.
Kristen Heather Gilbert (née Strickland; born November 13, 1967) is an American serial killer and former nurse who was convicted of four murders and two attempted murders of patients admitted to the Veterans Affairs Medical Center (VAMC) in Northampton, Massachusetts. She induced cardiac arrest in patients by injecting their intravenous therapy bags with lethal doses of epinephrine, commonly known as adrenaline, which is an untraceable heart stimulant. She would then respond to the coded emergency, often resuscitating the patients herself. Prosecutors said Gilbert was on duty for about half of the 350 deaths that occurred at the hospital from when she started working there in 1989, and that the odds of this merely being a coincidence was 1 in 100 million. However, her only confirmed victims were Stanley Jagodowski, Henry Hudon, Kenneth Cutting, and Edward Skwira.
Gerald Armond Gallego (July 17, 1946 – July 18, 2002) and Charlene Adell Gallego (née Williams; born October 10, 1956) were two American serial killers and rapists who were active mainly in Sacramento, California, between 1978 and 1980. They murdered at least eleven victims, mostly teenagers, often kept as sex slaves before killing them.
