An item on LAObserved says that
Alvaro Luna-Jara, a member of the Dogtown street gang, is suspected of shooting and killing 12-year-old Steven Morales on Avenue 58 in 1998. Luna-Jara fled to Mexico and was nabbed on a remote ranch near La Yesca in Nayarit by agents of the Agencia Federal de Investigacions and officers from the Nayarit State Judicial Police, acting on information provided by the Los Angeles County District Attorney’s Office, the LAPD, the Los Angeles Regional Fugitive Task Force, and the Mexico City Field Office of the United States Marshals Service.
He's been hiding in Mexico for eight years, and like many wanted murderers, he has been protected by the Mexican Government, which hates the death penalty. I checked—he's been mentioned on VDare.com:
Alvaro Luna Jara is charged with the murder of a 12-year-old boy and the attempted murder of three others. Although Jara is not a Mexican national, Mexico refused to extradite him because his parents are.

Luna-Jara was arrested by the AFI, Mexico's FBI. The press release issued by the US Marshal's Service says
Adam Torres, United States Marshal for the Central District of California, applauded the efforts of all the participating agencies for their continued cooperation and assistance and remarked, “Many people believe that they can commit any type of heinous crime and simply go to Mexico and hide. The District Attorney’s Office, the United States Marshals Service and Mexico’s federal agents have a message for those people…by working together and combining our recourses, we will find you and bring you to justice.”
But no mention is made either of the death penalty or life without parole, two things that the Mexican Government doesn't like happening to its citizens, no matter how much they deserve it.
