Authorities are reporting that a pack of wild dogs have mauled and killed four individuals over the last two weeks in a Mexico City park.

Residents of the Cerro de la Estrella, a semi-wooded area in a hilltop park surrounded by the city's lower class and Iztapapa district, first located the bodies of 26-year-old Shunashi Mendoza and a 1-year-old child on Dec. 29, according to Yahoo!.

Mendoza was allegedly found missing her left arm.  Prosecutors stated that her and the boy were partially eaten and bled to death.

On Friday, the bodies of a teenage couple that also died by losing massive amounts of blood were also found.

"Experts have established that due to the gravity of the wounds, at least 10 dogs were involved in each attack," Mexico City Prosecutors explained through a statement.

In the second mauling, 15-year-old Alejandra Ruiz and her 16-year-old boyfriend Samuel Martinez were said to be in the wild dog-ridden park on Friday afternoon.  Ruiz had contacted her sister Diana Ruiz around 7 p.m. screaming for help.

"Several dogs are attacking us, help me!" she said.  However, the call abruptly stopped soon after.

According to Milenio Television, Ruiz initially thought that her late sister was playing a joke and doesn't feel she was killed by dogs despite the phone call.

"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.  What's most shocking is that one of her breasts was mutilated.  There needs to be an investigation," she said.

Antemio Maya, president of the Street Dog Protection association in Mexico City, is also having a hard time believing that dogs could've killed the individuals found in the park.

"It's not the behaviour of street dogs to kill humans."

By Monday night, authorities captured 25 dogs, which included 10 females, eight males and seven puppies.  Experts are currently testing the dogs' hair for any human blood as well as the contents in their stomachs.  However, the authorities didn't disclose what they would do with the animals.
