No parole for violent Newman man

June 13, 2013 

A Newman man sentenced to serve eight years to life in prison for trying to strangle his elderly mother with his belt has been denied parole, according to the Stanislaus County district attorney's office.

Douglas Thiessen, 56, was convicted of first-degree attempted murder with the use of a weapon.

In June 2001, Thiessen argued with his 76-year-old mother inside her Newman home. Prosecutors said Thiessen removed his belt, placed it around her neck and twisted the belt, cutting off her air supply until she was unable to breathe or make a sound. She survived the attack and died in September 2001 of natural causes.

In 1981, Thiessen previously had shot and killed his brother, which was later determined to be self-defense. In 1995, Thiessen was convicted of felony battery causing serious bodily injury after beating his sister with a chair, according to prosecutors.

At the May 31 parole hearing in San Quentin State Prison, Deputy District Attorney Jared Carrillo argued for continued confinement based on Thiessen's history of violence against family members, lack of remorse and the danger to the public if he's released. During the hearing, Thiessen told the parole board, "I deny there was ever a crime," according to prosecutors.

The parole board said Thiessen has "denied and minimized all incidents of family violence, and poses an unreasonable risk of danger if released."

Thiessen will have another chance at parole in five years.
