Ruben Mize, an Eastside gang member accused—along with Bryan Medinilla, Ricardo Nava, and Raul Diaz—in the 2007 murder of Lorenzo Carachure, saw his older brother Robert Martinez testify against him this week. Martinez, who himself is facing serious state and federal charges including some related to this case, said he originally tried covering for Mize with an alibi when he was first arrested, but said his brother told him they had stabbed someone.
