The incident received notable national coverage on the July 22, 2006, episode of America's Most Wanted, leading to the capture of a suspect.
[1] When the men couldn't find any money in the home, they forced Barbosa to give them the key and alarm code to the check cashing business.
One month after the killings, police believed they had solved the case but soon realized that those suspects were not guilty due to a lack of evidence and were released.
The case had not been progressing steadily until Talisha Haithcox, 37, called the police and told them that her boyfriend, Eddie Williams, was involved with the murders of the four victims in McKinney, Texas.
Investigators collected a cigarette butt from the place where Cortez worked in Florida to use as DNA evidence against the suspect.
Also, investigators retrieved DNA evidence from the latex glove pieces and duct tape the suspects left behind in the house on the day of the murders.
[citation needed] Williams told police officials that before the shooting, he had been at Raul Cortez's house in McKinney planning to rob Cliff's Checking Cashing business, where Rosa Barbosa was the manager.
[7] Williams's relatively lighter sentence compared to that received by Raul Cortez was justified by his co-operation with police and his history of mental disabilities.
