Here's why dogs involved in fatal San Antonio mauling were returned to owner after prior attacks

The three pit bulls euthanized after a fatal mauling in Southwest San Antonio on Friday have been linked to three prior attacks on humans, the Express-News reports. Despite the dogs' history, they were eventually returned to their owner, Christian Alexander Moreno, 31, after those attacks due to a technicality under state law, according to the daily. Moreno was arrested Friday following the death of 81-year-old Ramon Najera, who died of injures sustained when two of the dogs attacked.
