Additional testimony revealed that on Dec. 8, 2007, while in a restaurant in Greensboro, Umana used a gun to shoot Ruben Garcia Salinas fatally in the chest and Manuel Garcia Salinas in the head after they "disrespected" his gang signs by calling them "fake." Umana fired three more shots as restaurant patrons scurried for cover with one witness running to protect her infant child. One other individual was injured by the gunfire.
According to evidence introduced during the trial, Umana later escaped to Charlotte with the assistance of other MS-13 members, where he was arrested on Dec. 12, 2007 in possession of a loaded Ruger that was later determined to be the murder weapon.
The jury found that, based on the evidence presented at trial and during the penalty phase, Umana shot and killed Ruben Garcia Salinas, a mason, and his brother, Manuel Garcia Salinas, a bricklayer, in aid of the racketeering enterprise known as MS-13.
According to testimony and evidence presented at trial, Umana attempted during his term of pre-trial incarceration to kill witnesses and MS-13 members who had become informants. During the first day of jury selection, during a pat down at the jail prior to sending Umana to the federal courthouse in Charlotte, U.S. Marshals recovered a knife that Umana concealed by attaching to his penis.
Umana was also found by the jury at the sentencing phase to have been responsible for three other murders in Los Angeles. One of these, a double murder, occurred in July 2005 on Fairfax Avenue. The third murder, and injury of two others, occurred at Lemon Grove Park in September 2005.
