Confessed killer Shaun Michael Gallon, 40, was sentenced Monday to three consecutive life terms for the 2004 killing of a young couple on a camping trip, and the 2017 murder of his brother.

Gallon pleaded no contest to the three murders on the eve of his trial last month, and Sonoma County Superior Court Judge Robert LaForge sentenced him today following a two-and-a-half-hour hearing, as the Associated Press reports. The resolution to the case comes nearly 15 years after the first two murders, and over two years after Gallon first entered police custody.

"It’s crystal clear to me you deserve to spend the rest of your life in prison and then some," LaForge said, according to the Santa Rosa Press-Democrat.

In attendance at the hearing was the mother of Lindsay Cutshall, who was fatally shot along with her fiancé Jason Allen while they were asleep in sleeping bags on Fish Head Beach in Jenner on August 18, 2004. Cutshall's mother showed the judge the wedding dress her daughter never got to wear, and read aloud from a letter written by Allen's parents.

The murder of the young Christian couple, who were 22 and 26 years old at the time, respectively, made national headlines because of the seeming randomness of it — the pair were on a three-day sightseeing tour of the California Coast after finishing work at a Christian white-water rafting camp in El Dorado County, and they had no connection to Gallon at all. The case went cold due to lack of evidence, even though Gallon had been a person of interest in the case 15 years ago. To this day, Gallon's motive in the dual homicide remains unknown.

Sonoma County Public Defender Kathleen Pozzi previously told the Santa Rosa Press-Democrat that Gallon most definitely suffers from mental illness, but further details about the case or his confession have not been made public since no trial ever took place. Gallon had previous run-ins with the law, including spending time in jail for a 2009 case in which he shot a man with a homemade bow and arrow. Just two months before the murders of Cutshall and Allen, Gallon was implicated in a bombing incident in Monte Rio that injured one woman. His motive in the latter case was reportedly to retaliate against a man he'd gotten into a fight with in a Guerneville bar, though the bomb injured the man's wife instead.

Gallon's social media presence, as SFist noted before, was filled with survivalist content and pictures of weapons, include a spear that he had fashioned himself.

He confessed to the 2004 killings while under questioning for the killing of his brother, Shamus Gallon, in March 2017. Both brothers lived with their mother in Forestville.
