MEXICO CITY — Wild dogs mauled and killed four people whose bodies were found over the past two weeks in a park on the edge of Mexico City, authorities said Monday. In one case, a teenage girl frantically called her sister with her cellphone to plead for help as the attack took place.
Neighbors of the Cerro de la Estrella, a partly wooded, hilltop park surrounded by the city’s poor and populous Iztapalapa district, found the bodies of a 26-year-old woman and a 1-year-old child in the area on Dec. 29, authorities in Mexico’s capital said.
One of the victims, 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 same park found the bodies of a teenage couple who had also bled to death.
‘‘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.
In the second attack, Alejandra Ruiz, 15, and her boyfriend Samuel Martinez, 16, had gone to the park Friday afternoon. The girl called her sister, Diana, at around 7 p.m. pleading for help.
‘‘Several dogs are attacking us, help me!’’ the girl screamed. The call then dropped.
Mexico City Public Safety Secretary Jesus Rodriguez warned against visiting the park and said all the dogs in the area will be trapped and checked to see if they were involved.
