Her boss became worried and called her brother who met him at Moya’s home on West 8th Street and S. Louisiana Avenue.

According to Weslaco Crime Stoppers, Moya’s body was found half-burned with one gunshot wound to her neck.

Investigators at the time said Moya was covered with gasoline.

During the investigation, there were some theories about her death, but no hard evidence was ever found to be able to take a suspect into custody.

Anyone with information about this case is asked to call the Weslaco Crime Stoppers at (956) 968-8477.

At the time, authorities said there was clear evidence of foul play.

In January 2021 the Hidalgo County Sheriff’s Office asked anyone with information about the double homicide to come forward.


“The family members of the victims and investigators are urging anyone with information regarding this case to PLEASE come forward,” the news release issued said.

Authorities say anyone with information on this cold case to call 956-383-8114, or anonymously to the Hidalgo County Crime Stoppers hotline at 956-668-8477.

Murder of a Harlingen mother, 1973

HARLINGEN, 1993. It’s one of the more infamous ‘who dunit’s’ in all of South Texas.

A young, Harlingen mother found with 25 stab wounds, a cutthroat, and a broken neck. No arrests were ever made in the killing of 23-year-old Candy Mora-Fletcher.

For 45 years, the case file remained quiet, until a new lead on the decades-old crime presented itself.

In 1973, the young mother was found in her apartment at the North Star Village on Lozcano Road. An investigation ensued, but no suspect was ever named.

More than four decades later, a glimmer of hope for those looking for answers.

Once the investigator was able to put the entire case together, it did not take long for investigators to realize there was one prime suspect that was left out there and everything seemed to point to him.

It was a man by the name of Lewis Brewster. He was the one who found Mora and called police.

Investigators believed the two were romantically involved.

Over the years, Brewster moved to California and when investigators traveled out to interview him, they say his answers and body language didn’t do him any favors.

Last November, the case took its final blow. Brewster passed away due to complications from diabetes.

Mora now rests at the Monta Meta Memorial Park in San Benito.
