Shawn Fowler, 44, of Tooele, Utah, was killed on July 6, 2018, on the Interstate 210 freeway in San Bernardino, California. Fowler was traveling with his wife and other motorcyclists when one bike developed mechanical problems. As Fowler and another rider pulled over to the side of the freeway around 4 a.m., someone traveling in the opposite direction allegedly fired shots. Fowler was pronounced dead at the scene; the other rider was critically injured but reported as stable, and Fowler’s wife, Denean, was unharmed.

Fowler was a member of the West Valley Chapter of the Mongols Motorcycle Club, but investigators have not determined whether that affiliation was related to the shooting. Fowler was a father of four and grandfather of seven; his family has publicly urged anyone with information to come forward.

If anyone witnessed the early-morning incident on I-210 or has information about vehicles or persons seen in the area, can you share what you know with investigators?
