What is the relevant evidence for a motion to suppress?

Because the key issue here is whether defendant was unlawfully detained, the relevant facts are taken primarily from Deputy Manila's testimony presented during the pretrial hearing on defendant's motion to suppress. Deputy Manila was the sole testifying witness. No other evidence was presented at the hearing. Our review is limited to the evidence that was before the trial court when it ruled on the motion to suppress. (People v. Garry (2007) 156 Cal.App.4th 1100, 1105, fn. 2 (Garry).)
