Carl "Charlie" Brandt (February 23, 1957 – September 13, 2004) was an American serial killer. A former resident of Fort Wayne, Indiana and longtime resident of the Florida Keys, Brandt shot his parents on January 3, 1971 when he was 13, killing his pregnant mother. His father survived. He spent one year at a psychiatric hospital before being released, and was never criminally charged. Then 33 years later on September 13, 2004, Brandt stabbed his wife and niece to death and then hanged himself in his niece's garage. This incident, Brandt's efficiency in killing his wife and niece, and his hidden obsession with human anatomy led investigators to look into the possibility that he had committed other murders since moving to Florida in 1973. The police have linked at least two homicides to Brandt.
