Group Funded by an Out-of-State Billionaire Releases Grossly
Exploitative Political Attack Ad Affecting Grieving Antioch Family

“California Justice & Public Safety PAC” has reported over $1M in spending in support of a misleading ad exploiting a grieving Antioch family whose 18 year old son, Matthew Butler, was robbed and murdered by a barrage of gunfire in 2009. Victim’s family has released a statement in response to the ad.


“California Justice & Public Safety PAC”, a special interest group funded by out-of-state donors released an exploitative campaign attack ad citing the 2009 high profile murder of Matthew Butler, an Antioch college student who was robbed and murdered by violent gunfire by Kayl McCutchen.

The mother of Matthew Butler, the murder victim cited in the ad, released the following statement in response. “Matthew was taken from us when he had so much promising life ahead of him. Our family has suffered deeply. No one should ever have to face the loss of their child.” said Eileen Blumhardt-Butler, mother of 18 year-old Matthew Butler who was robbed and murdered in a barrage of gunfire by Kayl McCutchen who turned 18 two weeks after he murdered Matthew. “Mary Knox understands that victims in our community deserve justice and she stood up for our family during many difficult moments.”

Kayl McCutchen was convicted by a jury of First Degree Murder with Use of A Firearm during the commission of a robbery. A judge sentenced Kayl McCutchen to life in prison as mandated by the law.

Knox has earned the endorsement of every law enforcement agency in the County, as well as state and local organizations such as the California Correctional Peace Officers Association, PORAC, the California Narcotics Officers Association and the California Gang Investigators Association. Mary has advanced social justice while preventing crime in Contra Costa County. She brought anti-bias training to the District Attorney’s Office and has fought to end discrimination against women in the Contra Costa County’s District Attorney’s Office.

The ad attacking Knox claims, “She even led the prosecution of a minor who was sentenced to life without parole.”

THE FACTS: McCutchen no longer faces a life sentence and is eligible for parole in 2033. In addition, during the time of sentencing Knox was mandated by state law, and the court was mandated by state law, to impose a life sentence.
The ad also claims the sentence in this case was, “a practice declared cruel and unusual punishment by the Supreme Court.”

THE FACTS: The Supreme Court ruled that, in the absence of the consideration of specific factors in a case involving a minor by the sentencing judge, a life sentence would violate the 8th Amendment’s proscription of “cruel and unusual punishment”. The sentencing judge considered each of those specified factors when she sentenced him to life twice. The third time he was resentenced to life, the 8th Amendment issue was no longer a factor as Kayl McCutchen had now been given the right to a parole hearing at 25 years by Prop 57.

McCutchen “No Longer Faces The Guarantee Of Dying In Prison” Due To Legislation Passed In 2018; Will Be Eligible For Parole In 2033. “Even if McCutchen’s life sentence is upheld, he no longer faces the guarantee of dying in prison. That’s because of the passage of SB 394 in 2018, which opens the door for juvenile lifers to gain freedom. In McCutchen’s case, he will be eligible for a parole hearing in 2033, according to state prison records.” [Mercury News, 3/12/20]
