Does an expert opinion need to be established to establish the corpus delicti?

supra, 197 Cal.App.2d at p. 212.) While an expert opinion may establish the corpus delicti (People v. Powers-Monachello (2010) 189 Cal.App.4th 400, 412-413), it is not required and the corpus delicti may also be established by circumstantial evidence such as the defendant's proximity to the fire, the time and method of the fire, and other "circumstances snapping the long arm of coincidence." (People v. Andrews, supra, 222 Cal.App.2d at p. 245.)
