Street dogs are being blamed for the deaths of four people in a park on the outskirts of Mexico City.

“Experts have established that due to the gravity of the wounds, at least 10 dogs were involved in each attack,” Mexico City prosecutors said in a statement.

Authorities have begun rounding up dogs living in the park to conduct tests aimed at determining if they were involved in the attacks.

In one case, the Associated Press reports, a teenage girl called her sister with her cellphone to plead for help as the attack took place.

“Several dogs are attacking us, help me!” the girl screamed before the call was disconnected.

Despite that, some animal activists are questioning whether the deaths should all be blamed solely on wild dogs,  and Diana Ruiz, who received the phone call, still doesn’t believe dogs were responsible for her sister’s death.

“What kind of dog can tear the skin from your whole arm and leave just bone and if it was an attack dog why didn’t it attack her neck?” Ruiz told Milenio Television. “What’s most shocking is that one of her breasts was mutilated.”

She said she later visited the place of the attack and saw no pools of blood.

“There needs to be a thorough investigation,” she added.

The attacks occured in the Cerro de la Estrella, a hilltop park surrounded by the city’s Iztapalapa district.

The first two bodies — a  26-year-old woman and a 1-year-old child — were found there Dec. 29, authorities in Mexico’s capital said.

The woman, Shunashi Mendoza, was missing her left arm, and prosecutors said that both she and the boy had bled to death and been partially eaten.

On Friday, visitors to the park found the bodies of  Alejandra Ruiz, 15, and her boyfriend Samuel Martinez, 16. Both had bled to death.

Antemio Maya, president of the Street Dog Protection Association in Mexico City, said he doubts dogs could have killed the people found in the park.

“It’s not the behavior of street dogs to kill humans,” said Maya, adding that blaming street dogs for the deaths could make life difficult for the thousands of homeless dogs in the city.

“A lot of people get tired of their dogs and they simply throw them on the streets,” he said. “This is going to create a terrible hate for street dogs and that’s going to lead to even more abuse.”

It’s estimated that, in the city of 9 million people, the number of dogs range from 1.2 million to 3 million.

Mexico City Public Safety Secretary Jesus Rodriguez told Milenio Television that the four victims were not dumped in the area as some had suggested. He said all the bodies had bite wounds, and that the bites were inflicted both while they were alive and after they had died. He warned against visiting the park.

At least 100 police officers had trapped 25 dogs in the park by Monday night. (The photos in this post are of four of them.)

According to Maya, the trapped dogs included beagles, Maltese and poodles and most were probably abandoned pets or their offspring.

Experts will test the dogs’ hair for traces of human blood and also test their stomach contents. Authorities haven’t said what they plan to do with the dogs.

Previous attacks by feral dogs have occured in Mexico City’s famed Chapultepec Park, but none fatal. After one attack there, authorities rounded up dogs, spayed and neutered them, and then either returned them to the park or found them homes.
