From an AP story headlined “Monkey business behind 911 call from California zoo”:

SAN LUIS OBISPO, Calif. (AP) — Cops usually have a prime suspect. In this case it’s a primate suspect.

The San Luis Obispo County Sheriff’s Office believes it was a little Capuchin monkey that called 911 from a zoo last Saturday night.

The call disconnected and dispatchers tried to call and text back but there was no response, so deputies were sent to investigate, the office said in a social media post.
