The documents and interviews with key witnesses in the case portray Torrez as a man obsessed with his wife’s actions in the final days of their crumbling marriage. Specifically, his desire to keep tabs on his wife’s movements and conversations as she began a new relationship. Reports indicate the couple, who had three children together, was separated at the time.

Vilet Torrez disappeared on March 31st, 2012. Surveillance video showed Vilet returning to her gated community early Saturday morning. Cid Torrez told police she never made it to her house. But the arrest report says the couple’s oldest daughter believed her mother was home because she awakened by a strange noise in the bedroom next door overnight.

The girl told police she heard “howling” and “crying” coming from the room and “she then heard her father in the other room sniffling and saying, ‘No you wake up’ a couple of times.”
