The state's highest criminal court has turned down an appeal from a former Rio Grande Valley gang member sent to death row for participating in a robbery where nearly a dozen men posed as police and killed six people during a raid at an Edinburg drug stash house.
Juan Raul Navarro-Ramirez was the first of three Tri-City Bombers members condemned for the January 2003 massacre of rival gang members.
A fourth man involved in the staged raid was given the death penalty in another case.
Attorneys for the 31-year-old Navarro-Ramirez raised 19 allegations challenging his 2004 conviction and sentence.
The Texas Court of Criminal Appeals on Wednesday agreed with the trial court in Hidalgo County that the appeal be denied.
Navarro-Ramirez does not yet have an execution date.
