[I]n 2001 decedent took his original copy of the 1997 will, urinated on it and then burned it. We hesitate to speculate how he accomplished the second act after the first. In any event, decedent’s actions lead to the compelling conclusion he intended to revoke the 1997 will.
Estate of Stoker, 193 Cal. App. 4th 236 (Cal. 2011)
