Matthew Self was a 17-year-old McKinney, Texas high school student and linebacker for McKinney North High School who died after being shot on March 12, 2004. That afternoon he and friends Austin York and Mark Barbosa went to the home of Rosa Barbosa. Unknown to them, three armed men — identified as Eddie Williams, Javier Cortez, and Raul Cortez — had followed Rosa home and were holding her hostage to force access to the check-cashing store where she worked.

When Matthew and the others arrived, the intruders forced Matthew, Austin, and Mark into a bedroom and shot them; Rosa Barbosa was also killed. Matthew was airlifted to Baylor University Medical Center in Dallas and died the following day. Multiple early leads and false confessions hampered the investigation before arrests were later made.

Does anyone have information about Matthew, his friends, or the events at the Barbosa home that afternoon?
