Elias Alvarez Hernandez, the coordinator of federal police in Baja California state, says the men were allegedly part of an immigrant smuggling ring. Twenty-one immigrants were found with them when the men were detained near Tecate on Saturday.

Hernandez says the suspects are two brothers and two taxi drivers who allegedly worked for them. Police seized four guns during the detentions.

Hernandez told a news conference that one of the suspects told police another man detained Friday with a 9 mm pistol in his possession was the one who shot agent Rosas.
