What is relevant evidence in a murder case?

To be admissible, evidence must be relevant. (Evid. Code, 350 ["No evidence is admissible except relevant evidence"].) Under Evidence Code section 210, "'[r]elevant evidence'" is evidence "having any tendency in reason to prove or disprove any disputed fact that is of consequence to the determination of the action." "The trial court has broad latitude in determining relevance. We review such a ruling for abuse of discretion." (People v. Howard (2010) 51 Cal.4th 15, 31-32 [gun "found, concealed in shrubbery, near the crime scene and the apartments where defendant was seen on the night of the murder" was "plainly relevant to establish defendant's participation in the attempted armed robbery"].)
