John Floyd Thomas Jr.

John Floyd Thomas Jr.  (born July 26, 1936) is an American serial killer, serving a life sentence without the possibility of parole for the murders of seven white women in the Los Angeles area during the 1970s and 1980s. Police suspect Thomas committed 10 to 15 more murders.

On April 1, 2011, Thomas pleaded guilty to the seven counts of murder as part of a deal to avoid the death sentence. Investigators have said Thomas is possibly one of the most prolific serial killers in the city's history.

Early life
Thomas was born in Los Angeles and his mother died when he was 12 years old. He was later alternately raised by his aunt and a godmother. Throughout his childhood, Thomas attended public schools, including Manual Arts High School in Los Angeles. Thomas served in the U.S. Air Force in 1956 for a brief period of time. While stationed at Nellis Air Force Base in Nevada, a superior noted that Thomas was regularly "late" and "slovenly" in appearance.

He received a dishonorable discharge, according to his military records, and was arrested for burglary and attempted rape in Los Angeles. Thomas was convicted of these crimes and sentenced in 1957 to six years in the California state prison system. As a result of a pair of parole violations, Thomas remained incarcerated until 1966.

Case history
The first wave of murders came in the mid-1970s, when police were on the hunt for a serial killer targeting older women in the western districts of Los Angeles, which led to the police dubbing the killer the "Westside Rapist." The killer's calling card was letting himself into the homes of elderly women who lived alone, raping them, either choking or suffocating them and leaving pillows or blankets over their faces after the attacks.

The killings appeared to stop in 1978, leaving at least 17 elderly women dead. However, in the mid-1980s, the police in the Pomona Valley area became aware of a serial killer with the same modus operandi as the "Westside Rapist." The killer, who was dubbed the "Southland Strangler," also used blankets or pillows over his victims' faces. Those murders left at least five women in Claremont dead.

The killings again appeared to stop in 1989, but the two serial murderer cases were not thought to be connected. Both cases left more than 20 people dead.

CODIS launch and re-examination
In 2001, the LAPD launched the "Open-Unsolved Homicide Unit," which reopened cold cases that included biological evidence that belonged to the perpetrators. The unit started after the launch of CODIS, which used DNA evidence left in cold cases and compared it to the DNA in federal databases. One of the many cases looked at was the murder of 68-year-old Ethel Sokoloff, who was found sexually assaulted and choked to death in her home in November 1972.

The re-investigation proved that there was biological evidence that was left behind but previously not examined. Based on this, a male DNA profile of the suspected killer was made. In 2005, it was found that the biological evidence left at the murder scene also matched the evidence left at the murder scene of 67-year-old Elizabeth McKeown, who was found sexually assaulted and murdered in March 1976.

2009 arrest
On March 27, 2009, the California Department of Justice notified the LAPD that a CODIS DNA match had been made and the killer had been identified in the murders of Ethel Sokoloff and Elizabeth McKeown, as well as the victims in the cases being investigated by the Inglewood Police Department and the LASD.

The offender had been identified as John Floyd Thomas, a resident of Los Angeles. A review of Thomas's criminal history revealed that he was arrested a number of times between 1955 and 1978. His criminal convictions consist of multiple burglaries, many of which involved sexual assaults of his victims. Other than an arrest for prostitution in 1993, Thomas has not had any other known law enforcement contact during recent years.

When the "Westside Rapist" killings appeared to stop in 1978, it was around the time Thomas was convicted and sentenced to state prison for the rape of a Pasadena woman. Thomas was released in 1983 and moved to Chino, which coincided with the "Southland Strangler" murders in the Pomona Valley area. Those murders appeared to stop when Thomas took a job with the state workers compensation insurance agency in Glendale.

Thomas was arrested on March 31, 2009, and on April 2, 2009, he was charged with the murders of Ethel Sokoloff and Elizabeth McKeown. On September 23, 2009, he was charged with the murders of Cora Perry in September 1975; Maybelle Hudson in April 1976; Miriam McKinley in June 1976; Evalyn Bunner in October 1976; and Adrian Askew in June 1986.

A break in solving the related murders came in October 2008 when Thomas, then an insurance claims adjuster at the State Compensation Insurance Fund, provided a DNA sample to authorities in connection with an effort to create a database of such samples from convicted sex offenders in the state of California. He was held without bail at the LA County Jail.

Although he was charged with seven murders, investigators said they strongly believe he killed 15 or more women in the "Westside Rapist" and "Southland Strangler" period, and raped many more. On April 1, 2011, Thomas pleaded guilty to the seven counts of murder as part of a deal to avoid the death sentence for the Adrian Askew murder. He was sentenced to life imprisonment without the possibility of parole.
