RIVERSIDE (CBSLA.com) — A 40-year-old Corona mother has been sentenced Thursday to three years of probation for helping her daughter beat up a girl because she talked to her daughter’s boyfriend.

Nancy Veronica Hernandez was sentenced to probation and five months of community service following her guilty plea made on Sept. 7. Hernandez had pleaded guilty to assault resulting in great bodily injury in connection with the March 30 attack on a 13-year-old girl at a Corona park.

In exchange for her guilty plea, a misdemeanor count against Hernandez of contributing to the delinquency of a minor was dropped.

Prosecutors say Hernandez drove her daughter and another 15-year-old girl to a Corona park so they could fight a 13-year-old girl, identified only as Anayeli, because she was speaking with the daughter’s boyfriend at Centennial High School.

“It was a text message war that led to an argument over the phone and then a confrontation at the park,” Deputy District Attorney Gary Polk told City News Service.

During the fight, the two 15 year olds ganged up on the younger girl, with Hernandez shouting encouragement, Polk said.

“The mom’s behavior got out of control,” he said.

Some of the fight was captured on witnesses’ cell phones.

“The kids are fighting, and Hernandez is yelling, ‘(expletive) her up!”‘ Polk said. “The victim’s teenage brother tries to stop the fight, and Hernandez pushes him away, saying it’s not his business. Another guy comes up and tells them to stop, and she says ‘(expletive) you.’ You can hear the defendant saying ‘beat her ass’ repeatedly and loudly.”

The prosecutor says Hernandez also grabbed Anayeli while the other girls struck her.

The 13-year-old suffered a bloody nose and bruised face, including an injury to the jaw, according to Polk.

The two 15-year-olds, whose identities were withheld, were also charged with assault. Their cases are pending in juvenile court.
