Over the objection of prosecutors, Criminal Presiding Judge Jonathan Karesh on July 25 reduced a charge of felony assault to a misdemeanor, according to a report from San Mateo County prosecutors.
Mr. Imrie, a 25-year-old military veteran believed to be afflicted with post traumatic stress disorder, had pleaded no-contest to felony assault in May 2014.
Judge Karesh credited him with 644 days already served.
The incident in Woodside began with Mr. Imrie threatening to kill his 22-year-old cousin and himself, either with a knife or by dousing them both with gasoline and igniting it, prosecutors said.
The cousin took a gasoline can from Mr. Imrie and took knives from the kitchen and threw them up on to the roof, but while his back was turned, Mr. Imrie allegedly hit him on the back with the shovel then fled.
Deputies found him at the Menlo Country Club on Woodside Road, where he was taken into custody after resisting arrest, prosecutors said.
