Jason S. Allen, 26, and his fiancée Lindsay Cutshall, 22, were shot to death while camping on Fish Head Beach in Jenner, California, on the night of August 14–15, 2004. Both were found in their sleeping bags with a single gunshot wound to the head from a .45-caliber Marlin rifle; their bodies were discovered on August 18, 2004, when a helicopter pilot responding to a report of a stranded man on a nearby cliff located them.

The case remained unsolved for many years despite extensive publicity and leads. In May 2017 authorities announced a breakthrough: Shaun Gallon, a local man with a history of violent behavior and mental illness, was arrested and later confessed to the killings. Gallon had been known to police for other crimes, and his subsequent arrest followed the 2017 killing of his brother.

In 2019 Gallon was convicted of the Jenner beach murders and received multiple life terms plus additional years for other charges. The motive given was Gallon’s mental illness and there was reported to be no known connection between him and the victims.
