BONUS: A month of mysteries at the Dallas Zoo | 'Something Offbeat'

Strange things have been happening in recent weeks at the Dallas Zoo. First, a clouded leopard went missing from its habitat, which had been tampered with. Next, a 35-year-old vulture was found dead. Then, two emperor tamarin monkeys went missing, though they were later found in an abandoned home. Environmental writer Emma Marris, author of the book “Wild Souls: Freedom and Flourishing in the Non-Human World” joined “Something Offbeat” as the mystery unfolded to talk about zoos and if they are the right place for animals to live.
