DALLAS (AP) _ A Collin County jury has found 28-year-old Raul Cortez guilty of a 2004 quadruple murder.
The jury reached its verdict in the capital murder case Thursday night.
Cortez could get the death penalty for the slayings of Rosa Barbosa, 46; her Matthew Barbosa, 25; and his friends, Austin York, 18, and Matthew Self, 17.
All four were found shot to death inside Barbosa’s home in McKinney, a Dallas suburb.
Cortez proclaimed his innocence throughout the trial.
Co-defendant Eddie Ray Williams, who is mentally disabled, testified that he and Cortez killed the four victims in a botched robbery plot.
A DNA expert linked Cortez to latex gloves and duct tape found at the crime scene and a forensics analyst linked ammunition found in the victim’s bodies to a .25-caliber bullet found lodged in Cortez’s ceiling.
