Can a defendant defend against criminal charges by showing that a third person committed the crime?

"An accused may defend against criminal charges by showing that a third person, not the defendant, committed the crime charged. He has a right to present evidence of third party culpability where such evidence is capable of raising a reasonable doubt as to his guilt of the charged crime. But evidence of mere motive or opportunity to commit the crime in another person, without more, will not suffice; there must be direct or circumstantial evidence linking the third person to the actual perpetration of the crime. [Citations.]" (People v. Mackey (2015) 233 Cal.App.4th 32, 110-111.)
