2009 arrest
Thomas was arrested on March 31, 2009, and on April 2, 2009 he was charged with the murders of Ethel Sokoloff in 1972, and Elizabeth McKeown, in 1976. DNA matching former insurance adjuster Thomas was connected to two further crime scenes in West Los Angeles in the 1970s and one Claremont in the 1986.
A break in solving the related murders came in October 2008 when Thomas Jr. -- a man twice convicted of crimes of sexual assault -- provided a DNA sample to authorities in part of an effort to assemble an offender database in the state of California. Police arrested Thomas on April 2, 2009. He is currently being held without bail at the LA County Jail.

Case history
In the first wave of killings in Los Angeles in the mid-1970s, a man police nicknamed the "Westside Rapist" entered the homes of elderly women who lived alone, raped them and choked them until they passed out or died. The 17 who were killed were found with pillows or blankets over their faces. A decade later, and 40 miles to the east, five elderly women in Claremont were found raped and killed, also with blankets or pillows over their faces. The case soon became a cold case for the investigators until John Floyd Thomas came to light in 2009.
