Three women and a man suspected in last September's killings of 11 people in an indigenous community north of this capital were arrested Thursday, Guatemalan authorities said.

The latest arrests bring to 13 the number of people in custody in connection with the massacre, Attorney General's Office spokesman Ruddy Zapet said.

Four of the detainees are women and another is a teenage boy, he said.

All of the suspects belong to "Crazy Rich," a chapter of the Mara 18 gang, Guatemalan authorities say.

Investigators blame the Crazy Rich crew for the Sept. 7, 2013, murders of 11 people at liquor shops in San Jose Nacahuil, an indigenous village 27 kilometers (17 miles) from Guatemala City.

The Crazy Rich group is also thought to have been behind the Sept. 24 killing of Julio Estuardo Diaz Giron, Zapet said. EFE
