Mexicans protest dog detentions, tests negative - Article Photos 1/9

In this 12 picture composite released by the Mexico City's Attorney Generals Office on Monday Jan. 7, 2013, several dogs are shown behind bars after they were caught in the vicinity where where a woman, her baby and a teenage couple were found dead and covered in dog bites in two separate incidents in recent days. Authorities have captured 25 dogs near the scene of the attacks in the capital's poor Iztapalapa district, but rather than calm residents, photos of the forlorn dogs brought a wave of sympathy for the animals, doubts about their involvement in the killings and debate about government handling of the stray dog problem.
