“I just couldn’t believe it,” Barry Lipman, a former San Francisco Zoo board member, told KGO. “Why would anyone want a lemur?”

Lemurs are not easy to care for, added Lipman, who provides funding for the Lipman Family Lemur Forest.

Maki was last seen in his enclosure Tuesday night, investigators said. It’s unclear whether a suspect has been identified.

Police instructed anyone with knowledge of Maki’s whereabouts to call 911.
