On July 5th 1970, three young men, Thomas Victor Dolan (17) of Manhattan Beach, Thomas Hayes (19) of Hermosa Beach and Homer Clyde Shadwick (19) of Saginaw, Michigan were discovered by a passer-by on a beach in Santa Barbara, that straddled the University of California Santa Barbara building at Campus Point. Two of the young men had succumbed to their injuries, while the third, Thomas Hayes had been rushed to hospital in nearby Goleta in critical condition, after the three appeared to have been subjected to a frenzied attack with a bladed weapon while camping out in their sleeping bags on the night of the July 4th 1970. Fortunately for Thomas Hayes, he survived the brutal assault. The three had hitchhiked back from fireworks celebrations at Candlestick Park in San Francisco. The assailant/s took none of the victims possessions in an apparently motiveless attack.
This attack came approximately four months after the Hood and Garcia Murders, who on Saturday February 21st 1970, 11 miles east of these attacks, fell victim to a knife wielding assassin on a quiet retreat of East Beach, Santa Barbara, a crime some believe had the hallmarks of the notorious Zodiac killer, who terrorized Northern California in the late 1960s and early 1970s. As did the murders of Robert Domingos and Linda Edwards on June 4th 1963, a couple who were brutally gunned down while fleeing for their lives from a remote beach, situated 3.32 miles east of Gaviota State Park and alongside Highway 101, approximately a five-hour drive from Vallejo, California.
Detectives drew parallels between the Sleeping Bag Murders and the Hood and Garcia slayings, yet to this day no arrests have been forthcoming in either case. Approaching her 80th birthday in 2004, Donna Dolan, the mother of Tommy Dolan asked police to re-open the case, fearing she may never see justice for her son. “[Investigators] have the hatchet", Donna Dolan said. “There was also a knife or a sword that have never been in the evidence room, but they know what it was because of the wounds. Any blood was from [Tommy Dolan and Homer Shadwick] – the perpetrators weren’t hurt in any way because the boys were sleeping in sleeping bags and they couldn’t even defend themselves … I was told by the detective at the Dept. of Justice that he would use anything he could find some DNA on".

This case entered the courts in the early 1970s, with respect to the culpability of the beach-front property owners allowing Thomas Victor Dolan and Thomas Hayes to stay there on the evening of July 4th 1970, resulting in serious injury and death of the two individuals. Here is part of the ruling, which was decided on December 13th 1973 in the Court of Appeal, Second District, Division 5 of California.
On or about the evening of July 4, 1970, Hayes and Dolan entered the beach-front property located within the confines of the University of California Santa Barbara campus and remained there after dark. While they were on the beach, they were assaulted and beaten by a person or persons unknown, and as a result Hayes sustained severe personal injuries, and Dolan died.
Plaintiffs alleged that the beach was owned, maintained, and supervised by respondents, and that persons entering the beach did so with the implied and express permission and encouragement of respondents; that the invitation to enter the beach area extended to the hours of darkness; and that respondents ‘did create and permit’ a dangerous condition to ‘come into existence and be created on the above described beach property in that the defendants, and each of them, knew, or should have known in the exercise of ordinary care that in addition to members of the general public that were expressly and/or impliedly invited to use the beach front property during the hours of darkness, as aforesaid, other highly undesirable people frequently used and frequented the above-described beach area during the hours of darkness and that serious and dangerous and harmful crimes had been committed in said area prior to the date in question; that the defendants, and each of them, with the above knowledge, either actual or implied, did fail to properly and adequately protect, patrol, police, govern or supervise the above-described area during the hours of darkness to prevent injury and damage to members of the general public occupying said property. Plaintiffs sought relief on the theory that respondents' activities with respect to this beach-front property created a dangerous condition, as defined in Government Code section 830(a).
Respondents' general demurrer to the complaint was premised upon two contentions pertinent to the issues: (1) that Government Code section 845 affords governmental entities absolute immunity for their failure to provide adequate police protection; and (2) that the beach (the physical condition of the property) was not a dangerous condition as defined by the Government Code. link.
The Hillside Daily News, Michigan July 14th 1970
'Detectives said Sunday the victim of a double slaying on a beach a week ago has been identified as an Army deserter carrying a friend’s identification so he wouldn’t be caught. Homer Clyde Shadwick, 19, of Saginaw, Michigan., was hacked to death as he slept on a University of California campus beach with two acquaintances after attending a Fourth of July fireworks display. A California youth also was slain, and another has been in critical condition since the attack. Officers first thought Shadwick was Larry Steve Hess, 20, of Lagrange, Indiana, because that was the name on all identification cards in his wallet. Fingerprints received from Florida, where Hess had an arrest record, proved the victim was not Hess. Final identification was made after the FBI was able to match the victim’s fingerprints with Shadwick’s.
Shadwick’s sister was located in Seaside, California, and she identified the body. Detectives also found Hess living at the home of Shadwick’s sister and her husband. Hess said he was unaware he had been listed as the victim. Hess told officers he and Shadwick lived together in Saginaw before hitchhiking to the coast in June. Shadwick was listed as a deserter from Ft. Lewis, Washington, since October. He and Hess closely resembled each other, deputies said. Detectives did not know how Shadwick met up with Thomas Victor Dolan, 17, of Manhattan Beach, and Thomas M. Hayes, 19, of Hermosa Beach, but think they met while hitchhiking. The trio apparently decided to spend the night on the beach after watching a fireworks display. The bodies of Shadwick and Dolan, beaten and cut up by a knife and a machete like weapon, were found Sunday morning. Hayes has not fully regained consciousness. No arrests have been made in the case.'
