Escaped California prison inmate convicted of murder kills police commander in Mexico: report

A convicted murderer on the run since his escape from custody in California last year is now wanted for killing a Mexican police commander in an elite unit known as "the Gringo Hunters" after a shootout with authorities this week.

The unit was trying to arrest Cesar Hernandez, 34, who remains wanted in the U.S., in the border city of Tijuana when a shooting occurred. Mexican police commander Abigail Esparza Reyes, the head of the unit dedicated to capturing American suspects in Mexico, was shot and killed, Reuters reported.
