The Court of Appeal found that insufficient evidence supported the juvenile court’s finding that appellant had committed grand theft of a cell phone valued in excess of $950 where two witnesses testified that (1) they were certain they had chased the thief because they kept him within their sight the entire time; (2) that they never saw appellant take the phone and never saw the phone in appellant’s possession; and (3) that police and park security arrived less than a minute later and detained appellant. However, there was no testimony that appellant had either passed the phone to an accomplice or discarded it, and the victim’s phone was not found on appellant’s person.
