Ventura County District Attorney Erik Nasarenko announced today that Pedro Ocampo Alvarez (DOB 06/29/68), of Oxnard, was convicted on November 4, 2026, of 11 felony counts of child molestation. Alvarez waived his right to a jury trial, opting for a court trial conducted by Ventura County Superior Court Judge Paul Feldman. Judge Feldman found Alvarez guilty of four counts of lewd acts upon a child, three counts of using a child for sex acts, two counts of unlawful sexual intercourse with a child 10 years old and under, and one count each of oral copulation with a child 10 years and under and possession of child pornography. The special allegations of substantial sexual conduct and the victim being particularly vulnerable were found to be true.

Deputy District Attorney Tessa McCarty, a member of the Ventura County District Attorney’s Office Sexual Assault Unit, prosecuted the case.

“I am deeply grateful to the victim for her bravery and strength throughout this process,” Ms. McCarty said. “Coming forward and participating in the pursuit of justice takes tremendous courage and I hope this conviction brings her closure and the justice she so rightfully deserves.”

Ventura County District Attorney Erik Nasarenko announced today the results of Operation Night Fall, a countywide enforcement operation targeting individuals suspected of producing, distributing, and possessing child sexual abuse material (child pornography). The operation was conducted from September 21, 2026, through October 8, 2026, by the Ventura County District Attorney’s Office Bureau of Investigation, with assistance from the Ventura County Sheriff’s Office, Oxnard Police Department, Simi Valley Police Department, Ventura Police Department, California State Parole, and the Federal Bureau of Investigation.

During the operation, investigators served 24 search warrants, including seven at residential locations, to gather evidence related to these investigations. Seven individuals were arrested in Ventura County in connection with the operation.

“Protecting children from sexual exploitation is a central mission for our office and we will continue to aggressively pursue those who seek to harm them,” said District Attorney Erik Nasarenko. “Operation Night Fall demonstrates the importance of coordinated law enforcement efforts in identifying offenders, securing critical evidence, and holding those accused accountable.”

Ventura County District Attorney Erik Nasarenko announced today that four members of a family-run criminal enterprise have been sentenced to state prison for operating illicit massage businesses, running commercial sex operations and laundering the proceeds through financial institutions, real estate and other assets.

Xiangwei Ma (DOB 07/15/70), identified as the head of the organization, was sentenced to 14 years 8 months in state prison. Xiangdong Ma (DOB 09/10/72) was sentenced to 10 years in state prison. Li Ma (DOB 02/18/66) received a sentence of 5 years 4 months in state prison, and Ming Ma (DOB 10/18/85) was sentenced to 4 years 4 months in state prison.

“Behind the doors of seemingly legitimate massage businesses in Ventura County was a criminal enterprise that exploited vulnerable women and generated enormous profits,” Senior Deputy District Attorney Rikole Kelly said. “These convictions send a powerful message: our communities will not be a marketplace for commercial sex, and those who profit from exploiting others will be held accountable.”

“Despite waiting nearly 30 years for justice, the victim’s family never wavered in their belief that one day all the men responsible for the victim’s murder would be successfully prosecuted,” said Senior Deputy District Attorney John Barrick. “Special thanks to the Ventura Police Department for their dedication and hard work regarding this case, which would not have been solved but for their tireless efforts.”
