Federal prosecutors charged a San Francisco man with manslaughter and driving while intoxicated in a crash that killed a renowned cyclist in the Presidio this past spring.
Arnold Kinman Low, 81, was indicted Wednesday by a federal grand jury on two felony counts stemming from the April 4 collision that claimed the life of 44-year-old national bicycling champion Ethan Boyes in early April.
The United States Park Police, which investigated the crash, determined that Low was drunkenly driving through the federally owned Presidio around 4 p.m. that day when he struck a cyclist on Arguello Boulevard just south of Washington Boulevard.
That cyclist turned out to be Boyes, who died soon after at a nearby hospital.
Boyes was known as a USA Cycling Masters Champion and the holder of the national record in the “flying start” 500-meter time trial.
The crash ignited calls in San Francisco’s cycling community for protected bike lanes and safer streets.
In response, the Presidio Trust agreed to implement some infrastructure changes, such as narrowed car lanes, more warning signs and guardrails for the bike lanes.
Low is set to make his initial appearance in federal court in San Francisco next Wednesday before U.S. Magistrate Judge Alex Tse.
Assistant U.S. Attorney George Hageman is prosecuting the case with the assistance of Erick Machado.
