WALNUT CREEK — When a Walnut Creek policeman responded to a 911 hangup call last November, the driver of a parked car explained the call away; he told the officer his ex-girlfriend had been following him, trying to start an altercation, so he called the police.

In the backseat was a young woman “crying hysterically,” according to the officer’s report. She was unable to speak, but slyly typed a two-word message on her phone and turned her screen toward the officer. Her message read, “He’s lying.”

By the end of the police investigation, the driver, 22-year-old Amani Dupre Jackson, had been charged with human trafficking, assault and domestic violence. By February, he and two women had been charged in an alleged criminal conspiracy to convince the victim not to testify, and to delete evidence off Jackson’s phone.

Police describe Jackson as a member of the Del Paso Heights Bloods, a subset of the Bloods criminal gang based in Sacramento. Jackson has pleaded not guilty and his trial has been set for mid-April, according to court records.

Court records describe Jackson’s November arrest in Walnut Creek, saying officers were first called to a parking lot near the corner of Arroyo Way and Civic Drive after an “unidentified female” called 911 and hung up. All the dispatcher could hear was a woman crying and a man asking where his phone was.

After reading the woman’s message to him, the officer — listed in court records only as “Officer Clemente” — separated Jackson and the woman, and interviewed her. She told police Jackson had punched her in the head and choked her for 10 seconds.

Jackson denied all this when questioned by police, saying it was another woman — a family member — who had fought with the alleged victim, and that he was trying to break it up. He said he called 911 and was more or less acting as a peacemaker.

In a subsequent interview, the woman told police that Jackson had spent two years in prison, and before that was “pimping her out,” according to an officer’s statement. She said he would drive her to San Francisco, or Oakland, drop her off at street corners with a box of condoms, and tell her not to call for a ride until all the condoms were gone.

She usually made around $1,000 to $1,500 a night, and Jackson would have sex with her if she met her quota, the woman reportedly told police. She said the argument that led to the fight in Walnut Creek happened because she had refused to go to the San Pablo/Richmond area and perform “tricks,” or sex acts for money.

But the story doesn’t quite end there. In February, a grand jury indicted two women — Channel Jackson and Essence Littlepage — on charges of conspiracy and dissuading a witness, for allegedly plotting with Jackson to get the victim to change her statement. In phone calls from county jail, Jackson reportedly also told them to delete evidence from his phone and other electronic devices.

REDWOOD CITY, CA — A Richmond man was arrested Thursday on suspicion of committing lewd acts with a child under age 14 while inside his vehicle, the San Mateo County Sheriff’s Office announced Friday.

Victor Alfonso Paredes-Castro, 34, was taken into custody in connection to an assault that happened on Feb. 23 and involved a family member of his girlfriend, according to the sheriff’s office. The incident occurred in an unincorporated part of San Mateo County, near Redwood City, officials said.

“The victim reported the incident immediately after it occurred, however the suspect fled the scene before deputies arrived,” the sheriff’s office said in a news release.
