Justen Hall, 38, is scheduled to die by lethal injection at 6 p.m. CST (0000 GMT) at the state's death chamber in Huntsville for the murder of Melanie Billhartz on Oct. 28, 2002.
According to prosecutors, Ted Murgatroyd, a recruit of Hall's gang, got into a fight with Billhartz that day in her truck on a trip to a convenience store in El Paso County.
When the pair returned to the drug house where gang members were gathered, Hall decided to killed Billhartz so she did not report the fight or the drug house to
police, according to court documents.
