Wild dogs have mauled and killed four people in a park on the edge of Mexico City.
People who live near Cerro de la Estrella first found the bodies of a 26-year-old woman and a one-year-old child in the area on 29 December. Prosecutors said they bled to death and were partially eaten. Last Friday visitors to the same park found the bodies of a teenage couple who had also bled to death.
Alejandra Ruiz, 15, and her boyfriend, Samuel Martinez, 16, had gone to the park on Friday afternoon. The girl called her sister Diana Ruiz at around 7pm pleading for help. “Several dogs are attacking us, help me!” she screamed. The call then stopped.
