Eight more people were found dead Thursday in a vacant lot in the south-east of the Mexican city of Tijuana, bringing the total of gruesome finds by police to 32 bodies this week alone, DPA reported. The killings on the border with the United States appeared to be part of the country's escalating drug war, officials said. According to the attorney general's office in the northern state of Baja California, the eight dead showed signs of having been killed by organized crime. The authorities found 16 dead bodies of alleged victims of organized crime in Tijuana Monday, and eight more Tuesday in the same city. The bodies found Thursday had been left in a vacant lot that separates a middle-class condominium building from an industrial park, the authorities noted. "Here are your people, bricklayer," read a message found by the bodies. The bodies found Tuesday had a message that referred to an "engineer." Police sources later said that this is how drug traffickers refer to the current boss of the cartel formerly led by the brothers Arellano Felix. Tijuana, right on the border with the United States and the stronghold of the drug gang of the Arellano Felix, is also a key point of access to the northern country for Mexican migrants, and a city favoured by many US citizens for weekend night-time fun.
