Archbishop Alberto Suarez Inda of Morelia made an impassioned plea for peace in Mexico during a funeral Mass for the 18 men who were kidnapped and killed while on vacation in Acapulco.

The bodies of the 18 tourists were found in a mass grave outside Acapulco. Officials have determined that all of the victims were family members or friends on vacation.

The archbishop called for justice and urged local and federal officials to unite in “stopping crime” in the country.

“We call on our representatives and leaders to unite in bringing about justice and putting an end to this disgraceful wave of violence,” the archbishop said.

“May the unjust deaths of these brothers and sisters be the seed that enables Mexico to end so much death and bloodshed,” he added.

Violence in Mexico has led to more than 29,000 deaths in the last four years.
