Four people died in an attack by wild dogs at an ecological reserve in Mexico City, according to forensic analysis, authorities in the Mexican capital said.

The Federal District Attorney's Office reported in a communique Monday that the injuries on the bodies found in the Cerro de la Estrella Reserve, east of the city, were "caused by dog bites."

Experts established that, in view of the severity of the injuries, 10 or more dogs were involved in each attack and that the four people died of external hemorrhage as a result of "injuries to the neurovascular bundle by canines."

As of Monday, members of the capital's Public Safety Secretariat had captured eight wild male dogs, 10 females and seven puppies that were living in caves of the ecological reserve.

The specialists are currently carrying out a thorough study of human blood on the animals' hair, and are also performing an analysis of their stomach contents, the DA's office said.

The statement said agents of the Public Safety Secretariat found two lifeless bodies on the Cerro de la Estrella mountain on Dec. 29.

Once the investigation began, it was determined that one body was that of a 26-year-old woman identified as Shunashi Elizabeth Mendoza Caamal, who was lacking the left arm and had huge bite wounds exposing bone.

The other body belonged to a child age 1 year and 8 months.

In another case on Jan. 5 this year, police went to the reserve after receiving a report on the discovery of the bodies of two teenagers between ages 15 and 16, identified as Alejandra Ruiz Garcia and Samuel Suriel Martinez.

Wounds on different parts of the bodies had characteristics of being produced before and after death, the DA's office said. EFE
