BROWNSVILLE, Texas (ValleyCentral) — The Cameron County Sheriff’s Office has reopened a 1980s murder investigation.

On December 29, 1980, deputies responded to the 600 block of N. Iowa in Brownsville regarding a body found at the location.

When authorities arrived, they found the body of 47-year-old Alfonso Cavazos inside the bedroom of his home, according to a news release from the Cameron County Sheriff’s Office.

A preliminary investigation revealed that Cavazos had been beaten to death with a blunt object, investigators said.

The crime scene was processed and investigators obtained information that led them to believe Cavazos may have been accompanied at the time by an unknown woman at the time of the killing.

According to the news release, the evidence collected will be re-examined with new DNA testing procedures and technology, which was unavailable then.
