Netflix’s ‘Aileen: Queen of the Serial Killers’ pieces together the story of Aileen Wuornos’s arrest, conviction, and years on death row through archival interviews and footage recorded by various filmmakers. Among the key voices featured is Steve Binegar, the former Police Captain with the Marion County Sheriff’s Office, whose investigative work was instrumental in Aileen’s capture. Binegar also testified against her during the trial, offering insight into the evidence and circumstances that led to her conviction. The documentary uses his perspective, along with others, to shed light on the case’s complex and often controversial nature.
Steve Binegar’s Investigative Work led to Aileen Wuornos’ Arrest
Steve Binegar came from a family dedicated to public service, with both of his parents having served in World War II. After graduating from Lake Weir High School in Ocala, Florida, in 1975, he enlisted in the United States Marine Corps, serving three years of active duty and achieving the rank of sergeant. Following his service, he joined the Florida National Guard and began working at the Sheriff’s Office as a corrections officer, later taking on the role of dispatcher. In 1985, he pursued Criminal Justice studies at the University of Central Florida and completed the Florida National Guard Officers Candidate School. The following year, in 1986, he was recruited by the FBI as a Special Agent and stationed in Richmond, Virginia.

He went on to earn his master’s degree from James Madison University. In 1988, he was invited to return to the Sheriff’s Office with the rank of Captain and was placed in charge of the Criminal Investigation Division. Between 1989 and 1990, he began investigating the murders of several middle-aged white men. The first case that caught his attention was the death of Troy Burress in July 1990. When the remains of Charles Humphreys were discovered in September the same year, Binegar noted that the bullets matched and suspected the crimes were linked. During the investigation of Peter Siems’ car, officers found strands of blonde hair inside, leading Binegar to consider the possibility that the killer might be a woman. His detailed investigation ultimately led to the arrest of Aileen Wuornos on January 9, 1991. Binegar later testified for the state, outlining the investigative process that resulted in her capture.
