On January 21st 1968, The San Diego Union and Daily Bee newspaper reported on the arrest of Flake Casto (21) in Clairemont, San Diego for the rape of two women near the University of California, San Diego. He was now the father of a month-old boy (born December 19th 1967) and worked at the Miramar Naval Air Station in Clairemont. He was captured by Thomas Hudson of 3260 Clairemont Mesa Boulevard Detective Guerin of the police sex crime detail stated that Casto was suspected of the rape of two 19-year-old girls on December 3rd 1967 and January 1st 1968. Just over a year previous, on November 22nd 1966, a male was reported by a woman, also 19 years old, who was walking towards the University of California, Riverside, when she was approached by a man driving a vehicle and subjected to an apparent rape. She stated that she had been held captive for more than two hours before making her escape. Her abductor remarked on the recent murder of Cheri Jo Bates and used language seemingly mimicked by the Confession letter author five days after the November 24th 1966 newspaper article describing this encounter.
The following year, on April 30th 1967, the author of the three Bates' letters again seemingly mimicked the Press-Enterprise newspaper from the same day. Jack Matthews, the Staff Writer of the Press-Enterprise newspaper, wrote about the murder of Cheri Jo Bates and the content in the confession letter, stating "The letter told of how Cheri struggled while she was being stabbed to death and the writer said there would be more killings to come". The author of the Bates' letters mimicked this wording by writing "Bates had to die, there will be more".
Flake Crawford Casto lived at 12021 Pomerado Road, only 1 1/2 miles from the location where Nikki Benedict was attacked. In fact, Pomerado Road bisected Poway Road just 921 meters from the attack site. An eyewitness described a young man running away from the crime scene. Flake Casto would have been 20 years of age on May 1st 1967. His first suspected rape attack in Clairemont on December 3rd 1967 was seven months after the murder of Nikki Benedict. The rape occurred sixteen days before his wife gave birth at Knollwood Hospital in Riverside.
The teenager years of Flake Casto overlapped with that of Cheri Jo Bates, murdered by a short-bladed knife on the Riverside City College campus on October 30th 1966 - so it's unusual that he would live so close to the murder location of Nikki Alexandra Benedict, also stabbed with a short-bladed knife in Poway on May 1st 1967, located 72 miles south of Terracina Drive (by crow). His family's residence at 8279 Marie Street, Riverside was 3 1/2 miles from the Riverside City College campus. I wonder if those brush offs were real?
