When police caught up with 32-year-old Pablo Ortiz shortly after the killing they noticed he had El Salvador's country code, 503, shaved into his hair. The Albuquerque Journal reports it's a gang sign for MS-13, which stands for Mara Salvatrucha.
The F.B.I. believes 10,000 gang soliders are marking their territory in 33 states and Canada.
We found this 52-minute video online. Journalist Lisa Ling has been following the gang's bloody path and posted this documentary on Google Video.
There is no indication that the second man being held in connection with the shooting, 22-year-old Marvin Lopez-Aguilar, is a member of the gang.
Each man is being held without bail on murder, robbery, kidnapping, and child abuse charges at the Bernalillo County Metro Detention Center. Police continue to look for at least one more suspect.
The female victim, a cook at Denny's, has still not been identified.
