The recordings made to 911 by one of the brothers attacked by the tiger at the San Francisco Zoo on December 25 were released on Tuesday.

The caller, who wasn’t identified, screamed at the dispatcher: “It's a matter of life and death!”

One of the Dhaliwal brothers, Paul or Kulbir, made the call from the cafe zoo and asked if it’s possible for a helicopter to be brought into the zoo to rescue his brother, the Associated Press reports.

At the end of the recording which lasts seven minutes, Carlos Sousa Jr., 17, was already killed by the Siberian tiger.

Around 5:27 p.m., four minutes after the call made by the brother to 911, an officer said into the radio "At the cafe, we have the tiger! We have the tiger attacking the victim!"

The recording was from police dispatch traffic.

One minute later another call on the radio says to stop the shooting.

An officer says: "We have the cat. We shot the cat. The victim is being attended to."

According to another 911 recording, a call made by a zoo employee showed that zoo employees didn’t believe that the cat was escaped. The male employee was talking with colleagues on a two-way radio.

He called around 5:05 p.m. at the sayings of another female employee who said that two brothers outside the café said that a cat had attacked them.

The woman can be heard on employee’s radio saying: "I don't know if they are on drugs or not. They are screaming about an animal that has attacked them and there isn't an animal out. He is talking about a third person, but I don't see a third person. He is saying he got attacked by a lion."

The male employee says that it can’t imagine that the man was attacked by a lion and that if that was true they could have seen it. The female employee says that the man is agitated and believes he is on drugs.

The man employee says to dispatcher: "They don't know if he got attacked by a lion. They are both very agitated and they might be on drugs."

On another line one of the two brothers is saying that his brother is dying there and is asking if it’s possible to fly a helicopter there.

It is possible that the victim on the phone was Kilbir, the older brother, who was the last one to be attacked by the tiger.

At 5:10 p.m. after the male employee finds out that the cat really got out, he evacuates the zoo.

On Tuesday the police said that it had a warrant to search the cell phones and the car of the Dhaliwal brothers. Police investigators believe that there is evidence that can prove the three have taunted the animal before escaping its den.

Dhaliwal brothers’ attorney, Mark Geragos, said that the three didn’t taunt the tiger.

According to some sources, Paul was drunk when the accident occurred, Kulbir was drinking and that both of them consumed marijuana, San Francisco Chronicle informs.

On Wednesday a hearing was scheduled in order to see if the city attorney’s office can search the items in another case, a civil one.
