A sentencing hearing for a convicted murderer erupted into chaos in Phoenix when the victim’s grieving father-in-law suddenly lunged at the defendant, striking him repeatedly before officers intervened.

Alberto Ontiveros Sanchez, 55, was arrested following the confrontation Wednesday morning at Maricopa County Court. The incident unfolded as Abel Uribe was preparing to be sentenced to life in prison for the 2022 killing of Sanchez’s son-in-law, 27-year-old David Navidad-Parra.

Sentencing Hearing Suddenly Turns Chaotic

Sanchez rushed toward Uribe at approximately 10:30 a.m. and struck him at least four times in the back of the head while Uribe was seated in the courtroom.

Sanchez’s attorney, Christian Leuders, later argued that years of grief overwhelmed his client at the hearing. According to the defense, Sanchez became particularly emotional after seeing behavior from Uribe that he interpreted as laughing and snickering.

Leuders asked the court to consider Sanchez’s history, noting that the 55-year-old had no previous criminal record, worked full-time and supported his children and grandchildren.

But Judge Kristin Culbertson made clear that the circumstances surrounding the case did not excuse violence inside a courtroom.

While acknowledging the intense emotions Sanchez may have experienced, the judge stressed that attacking someone during judicial proceedings could not be tolerated.

The Killing That Brought Both Families to Court

The confrontation came more than four years after Navidad-Parra disappeared under disturbing circumstances.

The 27-year-old U.S. Army veteran had gone on what was supposed to be a routine vehicle test drive when he vanished.

Investigators later found Navidad-Parra dead. The vehicle was discovered elsewhere after it had been set on fire.

The investigation eventually led authorities to Uribe after he was caught using Navidad-Parra’s credit card.

Uribe later entered a plea to first-degree murder and appeared in court to receive a life sentence.

Grief Leads to a New Criminal Case

Instead of leaving court after seeing Uribe face sentencing, Sanchez found himself facing legal trouble of his own.

Authorities charged him with aggravated assault on a bound or restrained victim, fighting and interfering with a judicial proceeding in connection with the courtroom confrontation.

Sanchez was subsequently released on his own recognizance.

The episode created a striking turn in a case that had already devastated the family: a grandfather who arrived at court to witness the sentencing of the man convicted of killing his son-in-law was himself arrested before the hearing was over.

His attorney is now asking the court to view those few chaotic moments against the backdrop of years of grief, while the judge has emphasized that even extraordinary emotion cannot override the rules meant to keep a courtroom safe.
