A mother of four with family in the Chicago area was killed and her sister critically wounded in a mass shooting that left 19 other people dead at a clandestine cock fight in Mexico’s western state of Michoacan Sunday.
Melissa Silva and her sister Arleth Silva, 16, were on vacation in Michoacan and were at the gathering near the town of Zinapecuaro when attackers opened fire, according to family.
