Three people, including Gonzales’ sister, testified Monday.

The prosecution and defense questioned Mary Ann Villafana about her involvement in Gonzales’ disappearance and death.

The siblings had a complicated relationship, and Villafana was their mother's caregiver.

Gonzales reported Villafana to adult protective services and the board of nurses after she allegedly didn’t check their mom’s vitals and violated Medicaid policies.

Their mother died weeks before Gonzales went missing.

Villafana denied the allegations, and told jurors she was investigated by those agencies and that she was not involved in her brother's disappearance.  

Another witness was the Cameron County pathologist who said Gonzales’ cause of death was a gunshot wound to the head, and manner of death was homicide

Testimony continues Tuesday morning.
