A life jacket that was found just fifty yards east of the Alcatraz Dock. The vest was saturated with stains (originally thought to have been blood but later ruled out as being grease), and there were teeth marks around the air tube. Based on this evidence, it was concluded that the inmate who wore it was desperately attempting to maintain enough air pressure to keep afloat. The prisoners had used binder claps to seal the air inside the vests, and these were probably unable to sustain adequate air pressure.

Another lifejacket was found by a couple walking along a section of Cronkite Beach in Marin County, almost four miles from the Golden Gate Bridge. The couple saw an object floating fifty feet from the shore, and waited a few minutes for it to wash up. It was a life jacket identical to the one made for West, which had been found on top of the cellhouse. This one also revealed additional interesting clues. The jacket was deflated, and the paper clip that held the air tube closed was missing. There was also a small tear at the seam, which had allowed air to escape. West stated that their plan had been to cut up the floats once they came ashore, and throw them back into the water.

The inmates concealed their discarded tools and equipment inside a five-gallon container, and then filled it with plaster. Investigators found wire, spoon handles, steel bars, the vacuum cleaner motor, staples, a homemade flashlight, ladle handles, and other bits of contraband embedded in the hardened plaster.

In the aftermath of the escape, correctional officers swarmed through the cellhouse, conducting meticulous inspections of every cell in B Block.

Ellsworth "Bumpy" Johnson, known as the "Al Capone of Harlem," was very well-liked by both inmates and officers. He was considered highly intelligent and a sophisticated inmate who would serve two terms on the Rock. It would be rumored decades later by a fellow inmate that Bumpy had assisted in the 1962 escape by helping arrange a pick-up by boat. This theory was never proven.

For decades people speculated as to whether this famous escape attempt had been successful. The FBI launched an intensive investigation, following every possible lead, and after spending nearly two decades painstakingly exploring physical and circumstantial evidence, the Bureau finally resolved that the inmates had not succeeded. There were several key points of the investigation that would ultimately cast doubt on the success of the escape attempt by Frank Morris, and John and Clarence Anglin. Through careful examination of the available evidence, one can form one’s own opinion as to whether or not the inmates made it to freedom. Numerous other reports were filed, including testimony from Alcatraz Officer Cliff Fish, who adamantly claimed that he had found a boat near the wharf at Angel Island, abandoned with copious amounts of blood on the flooring, which he stated was “impossibly more” that could have resulted from fishing. Another telegram alleged that a deflated raft was found on Angel Island with foot prints that leading away into the rugged terrain. No pieces of evidence were ever recovered or substantiated.

Consider the following evidence assembled by the FBI:

• The formal plan was to steal a car and then perpetrate a burglary at a clothing store. No reports of any such crime were filed in Marin County within a twelve-day period following the escape. None of the other surrounding counties, including San Francisco, San Mateo, Alameda, Contra Costa, Santa Clara, and Monterey County reported any related or suspicious crimes within a similar time period. It was also rumored that Morris, who had a passion for reading about aviation-related subjects, had talked about stealing a helicopter to make a rapid departure from the Bay Area. The FBI and the FAA came up with no potential leads on this angle, and in any case, it is very unlikely that Morris could actually fly a helicopter, as he had claimed to a fellow inmate.

• Sources reported that these three men had neither friends nor relatives with the resources to come to San Francisco and assist in the escape. The cost of putting a boat in the Bay night after night to assist in the escape would have been thousands of dollars. The families and friends of the trio were investigated regarding their financial resources, and their hypothetical role as accomplices was eventually ruled out. There would have been no possible way for the inmates to communicate with outside contacts in order to confirm the date and progress of their break.

• Critics on the other side of the debate claimed that the fact that no bodies were found amounted to “proof” that the inmates had made it successfully to the mainland. The reality was that it was common for people who perished in the Bay waters never to be found. On the very night of the escape, a thirty-three-year old African-American gentleman named Seymour Webb, reportedly despondent over a failed relationship, abandoned his car mid-span on the Golden Gate Bridge and tragically jumped to his death in front of sixty-two horrified eyewitnesses. Despite a quick response from the Coast Guard, his body was never recovered. The significance of this event is that the suicide entered the water about the same time as the escapees, and his body was never found.

• On June 19, 1962, Robert Panis, an eighteen-year-old Filipino male, also drowned in the waters of Half Moon Bay, approximately twenty-five miles south of the Golden Gate Bridge. On the day of the drowning, a Coast Guard Helicopter noticed a floating body wearing attire that matched that of the missing man. A surface vessel was dispatched to the location, but the authorities were never successful in recovering the body. The FBI cited this as another example of the extreme difficulty in recovering drowned bodies from the Bay. The Bureau also referenced the case of Theodore Cole and Ralph Roe, who escaped from Alcatraz in 1937. Despite intensive searches these men were likewise never located, and it was concluded that they had drowned.

• The Bay water temperatures ranged from fifty to fifty-four degrees. It was determined that exposure to the elements would have affected body functions after approximately twenty minutes. The showers at Alcatraz were always supplied with moderately hot water, in order to hinder inmates from becoming acclimated to the freezing Bay waters.

• On July 17, 1962 the Ship S.S. Norefjell, a Norwegian Freighter departing from Pier 38, reported seeing a body floating twenty miles northwest of the Golden Gate Bridge. The ship was en route to Canada, and the crew noted the sighting in the ship’s log, but did not make a formal report until returning to the United States on August 8, 1962. The SS Norefjell was not equipped with a transceiver that could broadcast on the marine radio bands used in the United States. The crewmembers logged the notation that sometime between 5:45 p.m. and 6:00 p.m. they noticed something bobbing in the water, and used binoculars to confirm that it was a body floating face down. The hands and feet were dangling down in the water, but the buttocks were clearly visible. Although bleached from the ocean and sun, the body was clothed in full-length denim trousers that appeared identical to prison issue. Coroners from San Francisco, San Mateo, Alameda, and Marin Counties all confirmed that a body could float for five weeks after drowning. The FBI determined this to be one of the most significant leads in the case. Their official report established that there was no other individual missing or drowned at that time who had been wearing similar trousers, and concluded that it was reasonable to state that this was likely to be one of the escapees.
