Prior to the outbreak of World War II, her singing career thrived, and she popularized one of her father's songs, Sa Kabukiran.

After the success of Sa Kabukiran, LVN Pictures decided to cast Jaime de la Rosa as Velez's leading man in her next film.

At 1:00 am of June 26, 1948, Anzures went to Velez' home at Pulog Street in Santa Mesa Heights, Quezon City.

At his trial, Anzures pleaded insanity, claiming to have been under a "fantastic spell" when he committed the crime, but later pled guilty and was sentenced to double-life imprisonment and was ordered to pay P5,000 each to the relatives of his victims.

Anzures was later pardoned by President Elpidio Quirino but died from tuberculosis shortly after his release; his exact motives for the killings were never determined.
