Locals discovered the partially-eaten bodies of a 26-year-old woman, missing an arm, and a 1-year-old boy in the Cerro de la Estrella in late December, the AP reports. Last week, people visiting the park, set in a densely-populated, low-income area, found the body of a 15-year-old girl and her 16-year-old boyfriend. Authorities said all the victims had bled to death. "Experts have established that due to the gravity of the wounds, at least 10 dogs were involved in each attack," prosecutors said. The teenage girl reportedly called her sister for help before the call cut off. Her sister wants an investigation, saying she doesn't believe dogs were behind the attack. "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?" A street dog advocate agrees, saying it's unlikely that dogs are to blame. In local newspaper pictures, the dogs look domestic; abandoned dogs may be forming packs nearby. Some 100 police are rounding up dogs in the park and testing them for human blood.
