DALLAS (AP) Two monkeys taken from the Dallas Zoo were found Tuesday in an abandoned home after going missing the day before from their enclosure, which had been cut. But no arrests have been made, deepening the mystery at the zoo that has included other cut fences, the escape of a small leopard and the suspicious death of an endangered vulture.

Dallas police said they found the two emperor tamarin monkeys after getting a tip that they could be in an abandoned home in Lancaster, located just south of the zoo. The animals were located, safe, in a closet, and then returned to zoo for veterinary evaluation.

Police said earlier Tuesday that they were still working to determine whether or not the incidents over the last few weeks are related.
