When police drained the canal at the end of April 1960, they found a green slide viewer near where they believe Irene Garza's killer had dumped her body.
The police appealed to the public for help in finding the slide viewer's owner.

Two days later, Father John Feit stepped forward to say that the slide viewer found in the canal was his. Feit, 27, had heard Irene Garza's confession in the rectory the night she disappeared.
Detectives' interest in Father John Feit deepened when they learned of an attack on another woman three weeks before Irene Garza's murder.Maria America Guerra, pictured here, fought off an attack from a man she thought looked like a priest inside a church in Edinburg, Texas.
In May 1960, Maria America Guerra picked out Father John Feit from a police lineup.
In 1961, Father Feit stood trial in Austin charged with assault with intent to rape Maria America Guerra. The jury deadlocked 9 to 3 in favor of conviction.Rather than face another trial, Feit later pleaded no contest to a reduced charge of aggravated assault and was fined $500.

As for the Irene Garza case, it grew cold. Father Feit eventually ended up at various monasteries.
In 2002, McAllen Police Chief Victor Rodriguez decided to reopen the investigation into Irene Garza's 1960 murder.
Chief Rodriguez brought in the newly formed cold case unit of the Texas Rangers. Ranger Rudy Jaramillo was leading the investigation.
In 2002, former monk Dale Tacheny came forward telling police that John Feit had told him he had killed a woman in the 1960s around Easter.

Father Joseph O'Brien, who had been the assistant pastor of the Sacred Heart Church in McAllen, Texas, also told police that Feit had made an admission of guilt.

Despite the new witnesses, Rene Guerra, the Hidalgo County District Attorney, does not think the new witnesses are viable.
Irene's family fought to get a jury to hear the case but in 2004, a grand jury did not indict John Feit. Feit was never subpoenaed and Father O'Brien and Dale Tacheny were never called to testify in person.
Writer Pam Colloff of Texas Monthly magazine wrote about the case in her 2005 article "Unholy Act".

John Feit left the priesthood in 1971. He is married with children and grandchildren and lives in Scottsdale, Ariz. He denies that he killed Irene Garza.
On Feb. 9, 2016, John Feit, 83, was arrested in Scottsdale, Ariz., in connection with the 56-year-old Texas murder case.
