LOS ANGELES – Jurors today convicted a 38-year-old man
accused of fatally stabbing an elderly couple in their Monrovia
home.
Alfredo Valenzuela of Monrovia was convicted of two counts of
first-degree murder for the July 2003 slayings of Bernice and Clark
Shaum. Jurors found true special circumstance allegations of
multiple murders, murder in the course of a robbery and murder in
the course of a burglary.
Jurors also found true a criminal enhancement that the defendant
used a knife in the commission of the offenses.
Los Angeles Superior Court Judge Lance Ito said the penalty phase
of the trial will begin at 9:30 a.m. on July 16. Valenzuela faces
life in prison without parole or the death penalty.
Deputy District Attorney Brook White of the Pasadena Branch
Office is prosecuting the case.
Valenzuela’s girlfriend, Shawna Robles, 37, was convicted in 2008
of two counts of special circumstance murder and was sentenced to
life in prison without the possibility of parole.
The victims, who were in their 70s, were lifelong family friends
whom the defendant had known since his childhood. Evidence presented
at trial revealed that between July 25 and 26, 2003, Valenzuela
entered the couple’s home through a bedroom window.
Upon entering, the defendant landed on Bernice Shaum and went on
to stab her more than 40 times, according to the evidence presented
in the trial. Valenzuela then opened the door for co-defendant
Robles, at which point the victim’s husband – who was sleeping in a
separate bedroom – awoke. Valenzuela and Robles then attacked Clark
Shaum, stabbing him at least 113 times, according to evidence
presented in court.
