UPDATE: Report called a hoax.

FLORISSANT -- Authorities say a report of a baboon or chimp on the loose in a Florissant subdivision was a hoax.A 14-year-old girl who claimed she saw the animal in her backyard and snapped a photo told police this afternoon that she actually found a picture of a baboon on the Internet and took a photo of it on her computer screen, police said.

Florissant police said the department spent much of the day investigating the incident. Police said the incident will be referred to St. Louis County Family Court for review.

The girl's mother had provided the photo of the baboon to city officials and news media. But an identical photo can be found in an Internet search and the story began to unravel.

The girl and her mother left their home with detectives at mid-afternoon to be interviewed at the police station.

Police Chief William Karabas told reporters then that his officers would continue to handle the report as real until it could be proven to be a hoax.

Officials said that St. Louis Zoo officials, who have been providing advice, confirmed that feces provided by the homeowner, reported to be from the back yard, was from some type of primate.
