STOCKTON — An 18-year-old man accused of attempted robbery and elder abuse against a 71-year-old Sikh man that was all caught on video surveillance will be sentenced next week.

Tyrone Keith McAllister showed no emotion and said little on Thursday morning as he was ordered to appear in court on Tuesday at 8:30 a.m. in Department 7B.

He pleaded guilty to one felony count of attempted robbery and is expected to serve one year in jail along and complete 100 hours of community service.

McAllister, the estranged son of Union City Police Chief Darryl McAllister, will likely be placed on five years of formal probation and was ordered not to contact Sahib Singh Natt and stay away from a central Manteca park where the assault took place on the morning of Aug. 10.

"Mr. McAllister, do you understand what's going on here today?" asked retired Judge Steven Howell, who was filling in for Judge Ronald Northup, to which McAllister responded with a simple "yes."

The elder abuse charge and associated allegations were dismissed in light of the guilty plea to the attempted robbery, according to the San Joaquin County District Attorney's Office.

"I've communicated the disposition with the victim's family and they are accepting of this disposition," Deputy District Attorney Janet Smith said.

Natt had just completed his second lap around Graystone Park when he was suddenly confronted by two young men just after 6 a.m. on Turquoise Way.

The confrontation quickly turned violent and left Natt on the ground. He had been kicked and spat on.

Authorities later recovered security video from a home across the park that showed one of the men in dark-colored clothing kicking Natt two times in the groin area as the other male looks on. Natt is knocked to the ground, hitting his head on the pavement with the impact causing him to lose his turban.

The two men begin to walk away, but the attacker runs back to the victim and not only kicks him again, but spits on him before departing for good.

Natt testified on Oct. 16 that he still feels the effects of the attack with injuries to his head, chest, arms, and lower abdomen.

Darryl McAllister has not been present in Stockton court for any of his son's court appearances. In a lengthy post on social media after the arrest, he said his son began getting into trouble with the law years ago. He cut ties from friends and family, associated himself with questionable people and spent several months in juvenile hall.
