Thien Ho, the current district attorney of Sacramento County, delivers the first official account of the investigation, capture and prosecution of Joseph DeAngelo, one of America’s most notorious serial predators. Known by many chilling names over the years, including the Visalia Ransacker, the East Area Rapist, the Original Nightstalker, and finally the Golden State Killer, DeAngelo terrorized California communities for more than a decade—and then disappeared without a trace for more than 30 years.

It's a tale Ho recounts in his new book The People vs. the Golden State Killer, from Third State Books. As the lead prosecutor on the case, Ho recounts the exhilarating and harrowing experience of bringing a cold-case killer to justice and putting him behind bars for life. Rather than focusing solely on the criminal and the crimes, Ho’s narrative centers the dedicated law-enforcement teams who never gave up their pursuit, and the courageous survivors of the GSK's crimes who fought to heal and regain control of their lives. Ho has hundreds of never-before-revealed details and firsthand insights, and this is the first time the public hears directly from the lead prosecutor who helped close the case.

A portion of the book’s proceeds will benefit Phyllis’s Garden, a nonprofit that honors a GSK survivor and champions victims’ rights.

Ho, who comes to Commonwealth Club World Affairs for a discussion with award-winning journalist Dion Lim, will also share his compelling personal story: a Vietnamese refugee whose family fled Saigon at the end of the Vietnam War; he arrived in the United States knowing no English. He rose from being an intern to being elected Sacramento County district attorney in 2022, becoming one of only 10 Asian American district attorneys out of 2,400 nationwide.

Note: Each in-person attendee will receive a free copy of The People vs. the Golden State Killer.
