Missing monkeys latest in a string of strange events at Dallas Zoo

The latest: Dallas Police say they received a tip that the monkeys may be at an abandoned home in Lancaster.

• Authorities are still asking for the public's help in identifying an individual in surveillance video.
• The person can be seen walking slowly down a nearly empty zoo pathway, looking around as he moves.
• "It was clear the habitat had been intentionally compromised," a zoo spokesperson tells Axios.

The big picture: This is the latest in a string of strange incidents at the zoo over the last month.

• Two weeks ago, Nova, a clouded leopard, escaped the leopard enclosure through a cut in the mesh. Police have opened a criminal investigation, assisted by the U.S. Fish and Wildlife Service, saying the cut was "intentional."
• The zoo found a similar cut at the langur monkeys' enclosure — though none of the monkeys left the exhibit.
• Last week, Pin, an endangered lappet-faced vulture, was found dead with what police called "an unusual wound."

Zoom in: Emperor tamarin monkeys would likely stay close to home if they left on their own, according to the zoo. Employees searched near their habitat and across the zoo's 110-acre property but didn't locate them.

• Dallas is under a winter weather watch, per the National Weather Service.

• Emperor tamarins are native to the southwest Amazon basin and not used to these temperatures.

Of note: The zoo has increased security efforts, including doubling the number of overnight security guards and adding cameras borrowed from Dallas police.

Flashback: Other zoos have experienced thefts recently, too.

• Twelve squirrel monkeys were reportedly stolen from a zoo in Louisiana over the weekend.
• Late last year, two Galápagos tortoises were stolen from a zoo in Florida.
• And last summer, a macaw stolen from a zoo in New Mexico was found dead.

Editor's note: This story has been updated to reflect the two emperor tamarin monkeys have been found.
