Four years earlier on February 28th 1962 the San Bernardino County Sun ran an article entitled 'San Bernardino Youth Knifed in Wild Attack on Redlands Road'. Somebody contacted me and pointed me in the direction of the source on Youtube, to which I will provide a link at the foot of this article. Here is the article text.
Charles Albert Schuler, 19, of 7695 Merito Avenue, was treated at Community Hospital for cuts on the shoulder, right elbow and left hand that he said was inflicted by a curved flooring knife.
His companions, Perry Lee Thomas and Bill Roan, both of San Bernardino, and Robert Claude Cockrell said they were attacked at Highway 99 and Alabama Street on the outskirts of Redlands about 5 pm Monday.
They said their three assailants, occupants of a pick-up truck, pushed in the windows of the hardtop in which the four were riding, and one of the assailants shoved in a pocket knife and started swinging it.
The four said they then got out of their car, but were chased by the other three, all of whom had knives. Witnesses said that Schuler was chased through heavy traffic. His shirt was cut to ribbons by his knife-swinging assailant.
After dodging knives for a while, the four youths got back in their car and fled. They said the three in the pick-up truck loaded the truck bed with rocks and debris, and chased the car four miles to Tippecanoe and Central.
One of their assailants rode in the truck bed and the other on a running board, hurling rocks and debris at the car, the four said. The truck was identified through a license number and three men were later picked up by Detective Jay D. Hughes.
Booked in the County Jail for questioning were Booker T. Washington (47), his son, John T. Washington (26) and Cleophus Martin (43) of 1577 Vine Street, all of San Bernardino. Detective William Paterson of the homicide division is investigating."
Cleophus Martin was born on 15th October 1917, which would have him 44 years of age on February 28th 1962, not 43, as referenced in the newspaper. Due to the rarity of the name and the location of San Bernardino, it could be argued that this was the groundskeeper/janitor who discovered the body of Cheri Jo Bates. This man likely had nothing to do with the murder of Cheri Jo Bates, and was unfortunate enough to discover the terrible events of the previous night, but it begs the question of how familiar the perpetrator was of the Riverside campus.
Was the murderer of Cheri Jo Bates familiar enough with the Riverside City College campus to know that the two properties either side of the attack site were empty? Did he have access to the Riverside library storage room to write on the underside of the desktop in relative anonymity? Did he use paper acquired from the Riverside college?
"A photocopying machine, where students could secure 8 1/2 X 11 inch black and white copy of printed or typed material, was available at the library for ten cents."
The photocopying machine would have been acquired by the college library in respect to the paper likely used by the college staff and students. The three Bates letters mailed on April 30th 1967 measured 8 1/2 X 11 inches, identical to the size offered by the photocopier in the library.
