Milo Mcintosh Imrie, 23, pleaded not guilty to all charges in December and has been in county jail on $25,000 bail.
A Superior Court judge suspended criminal proceedings at a Feb. 1 hearing and continued the case to Feb. 5 for the appointment of mental health professionals to evaluate Mr. Imrie, who may have post-traumatic-stress disorder, according to a report by the San Mateo County District Attorney's Office.
Were Mr. Imrie to make bail, he would have to stay in a residential treatment center, prosecutors said. Geoff Carr, his defense attorney, "expressed a doubt" as to his client's competency to stand trial, prosecutors said.
In the Dec. 12 incident, Mr. Imrie allegedly threatened violence to himself and to his cousin in his cousin's Woodside home, prosecutors said. Deputies arrested Mr. Imrie at the Menlo Country Club, to which he had fled after allegedly hitting his cousin with a shovel, prosecutors said.
