All month the Dallas Police have been investigating one strange occurrence after another at the Dallas Zoo. On Monday afternoon NBCDFW reported that police were looking for missing monkeys. 

The zoo animal care team members announced that two emperor tamarin monkeys were missing. And the habitat had been "intentionally compromised." 

According to a statement from the zoo, there was evidence that the habitat had been “tampered with.” And the missing monkeys were regardingtaken.

“Officers responded and the preliminary investigation determined an intentional cut was made into a tamarin monkey enclosure at the zoo,” the department said in a Monday statement.

On Tuesday police posted a photograph on Twitter. According to police “Detectives are looking to speak with the man regarding the two tamarin monkeys missing from the Dallas Zoo.”

The young man was recorded on video walking through the zoo. He was wearing a winter hat, blue hoodie, dark pants, and blue athletic shoes. When the photos were taken, he was eating Doritos.

Police are asking for help to identify the young man that may know something about the animal’s disappearance. 

No information was offered about the man, when the video was recorded, or if he is considered a person of interest in the case.

Missing monkeys is the third strange incident 

The zoo team insists that “Emperor tamarin monkeys would likely stay close to home — the zoo searched near their habitat and across zoo grounds and did not locate them.” the Dallas Zoo tweeted Monday.

Earlier this month, a clouded leopard escaped her enclosure. And the fence was “intentionally cut.” The female leopard, named Nova, was found on the same day she went missing. And Dallas police launched a criminal investigation into the incident.

Similar fence cuts were found inside the langur monkey habitat. No langurs escaped their habitat or appeared to be harmed or in danger, Dallas PD said in a press release at the time.

On Jan. 21, zoo workers discovered a rare, endangered vulture was dead in its enclosure. Initially the zoo described the vulture, named Pin’s death as “unusual” and claimed the bird did not die from natural causes.

Throughout the month the Dallas Zoo increased its security measures.

In a statement, they said they “... added additional cameras throughout the zoo and increased onsite security patrol to overnight hours. “And promised “safety and security measures” in order to “keep our animals and staff safe.”

Dallas Police are now investigating several strange incidents at the zoo. This includes the suspicious death of a vulture named Pin, a damaged monkey habitat, and the escape of a clouded leopard named Nova.
