A Phoenix courtroom erupted into chaos this week when a grieving father-in-law lunged across the room and punched his son-in-law's convicted killer in the head, moments after delivering an emotional victim-impact statement at the man's sentencing hearing.

Alberto Ontiveros Sanchez, 55, had just finished addressing the court on Sept. 22 about the 2022 murder of his son-in-law, U.S. Army Captain David Navidad-Parra, when he turned back toward the gallery, then pivoted and charged the defense table inside the South Court Tower in downtown Phoenix. He struck defendant Abel Uribe, who was handcuffed and shackled at the leg, four to five times in the back of the head with a closed fist before court security wrestled him away.

Sanchez's attorney, Christian Lueders, told the judge his client "lost it" after noticing Uribe laughing and snickering at the defense table as Sanchez walked back to his seat. The outburst forced the judge to halt proceedings and briefly clear the courtroom.

A killing that took years to resolve

Navidad-Parra, 27, a West Point graduate and Army officer, disappeared in December 2022 after arranging to meet Uribe for what was supposed to be a private vehicle sale. His body was found near 43rd Avenue and McDowell Road, and his car was later discovered burned more than 10 miles away in Glendale. Prosecutors said Uribe tried to use Navidad-Parra's credit card after the killing and told investigators he set the car on fire by breaking a gas line and using a cigarette.

Uribe, 33, pleaded guilty in August to first-degree murder and kidnapping. At Wednesday's hearing he was sentenced to life in prison, with the possibility of release after 25 years on the murder count, plus a consecutive 17-to-20-year term for kidnapping — the maximum the plea agreement allowed.

"I PERSONALLY CAN'T IMAGINE THE EMOTIONS THAT YOU MUST HAVE BEEN FEELING TODAY, BUT WE CANNOT TOLERATE THAT KIND OF CONDUCT IN COURT." — the sentencing judge, addressing Sanchez immediately after the attack

That response came from courtroom video obtained by local reporters. Sanchez now faces charges including aggravated assault of a bound or restrained victim and disrupting a judicial proceeding. Because the Maricopa County Attorney's Office has a conflict of interest in the case, prosecution of Sanchez has been handed to the Gila County Attorney's Office.

Despite the charges, the judge released Sanchez on his own recognizance, citing the family's grief and his lack of any prior criminal record; associates describe him as a legal U.S. resident of more than 30 years with steady full-time employment. Court officials have not said whether Uribe was injured in the attack.

The case now moves in two directions at once: Uribe begins serving his life sentence, while Sanchez awaits his own court date over the courtroom assault — a reminder, prosecutors say, of how raw and combustible a sentencing hearing can become when a family confronts the person who took someone they loved.
