A San Anselmo man arrested at Muir Beach on Sunday night for attempted murder after someone reported he was wielding an ax, had blood all over him and had tried to choke his mother, was charged this week with felony assault likely to cause great bodily harm. Louis Ernst, 24, who was charged in 2013 with driving under the influence, had his bail set at $500,000. He remains in custody, and is scheduled to enter a plea on Friday.
