MEXICO CITY — A 15-year-old girl found fatally bitten by dogs outside a Mexico City park in mid-December may have been the first victim of a feral pack suspected of killing at least four other people over the last month, prosecutors said Wednesday.

Authorities began capturing dogs in the park this week after a mother and her infant boy were found dead and covered in dog bites on Dec. 29 and the bodies of a teenage couple were found covered in fatal bites from as many as 10 dogs a week later.
