Gunmen killed eight fishermen in the popular Mexican surf resort of Puerto Escondido late on Monday, prosecutors said, in a rare shooting for a part of the country that has largely avoided serious gang violence.
The shark fishermen were in a house in the Pacific port when the gunmen entered and opened fire. Four were killed at the scene while the other four died soon after being taken to a local hospital, prosecutors from the southern state of Oaxaca said on Tuesday.
One of the main lines of investigation is whether the men also engaged in other activities at sea aside from fishing, the prosecutors said in a statement.
Shark hunters fish offshore using vessels larger than ordinary fishing boats.
Famous for the powerful waves that roll into the Zicatela beach, Puerto Escondido is a small resort frequented by visitors from the United States and Europe, particularly Italians.
