Melissa Silva and her sister, Arleth, were at the gathering near the town of Zinapecuaro when attackers opened fire, according to family.
MEXICO -- It was late Sunday night when a group of gunmen got out of the back of a snack truck and opened fire at a clandestine cock fight near the town of Zinapecuaro.
"They were there for vacation to celebrate the holidays," said the victims' brother, Alex Silva."They were there for a couple of months." Investigators found 15 vehicles that apparently belonged to the victims, one of which bore stickers with the logo of a criminal gang. Prosecutors said drug cartels and other criminal gangs had been fighting in the area.
The family is still making funeral arrangements for Melissa. Arleth was supposed to be back in school in Warrenville next week but her family now has no idea when she will be able to return.
