Haldeman, who was arrested last month on allegations of sexually assaulting boys and then released on bail hours later, was arrested again on Aug. 21 at his Menlo Park home on 20 sexual assault charges, according to the San Mateo County Sheriff's Office. Bail was set at $5 million.
After the original arrest generated numerous Bay Area media reports, eight more individuals contacted authorities to report being sexually assaulted by Haldeman, according to District Attorney Steve Wagstaffe.
Several of the molestations occurred after the victims had consumed alcohol, and involved fondling while viewing pornography, Wagstaffe said.
The victims' ages at the time of the alleged assaults ranged from 4 to 16 years old, Wagstaffe said.
Haldeman had been arrested on July 25 on two counts of "lewd and lascivious acts" with boys ranging in age from 8 to 13 years; the alleged assaults took place at his Menlo Park home and at the Ladera Recreation Center.
Although the Sheriff's Office said at the time of his arrest that Haldeman was a swim team photographer at the Ladera center, several people connected with the center have challenged that characterization, and Wagstaffe on Aug. 26 confirmed that Haldeman was only a parent volunteer rather than an employee of the center.
An official at the Ladera Recreation Center declined to comment on Haldeman's role at the center when contacted by The Almanac.
In addition to the information that one of the alleged assaults occurred at the church, Wagstaffe said on Aug. 23 that nine of the children interviewed by investigators reported improper lewd touching, while another case involved soliciting a sexual act with a minor with no actual contact, which is also a felony.
The soliciting charge involved a girl, and the others involved eight boys and one girl, Wagstaffe said.
One allegation has resulted in a charge against Haldeman of sodomy on a drunken 12-year-old boy, he said.
Many of the charges could result in a sentence of life in prison, Wagstaffe said.
Haldeman and his attorney, Chuck Smith, were due in court on Monday, Aug. 26, to enter a plea and seek a reduction in bail, according to Wagstaffe. The Almanac was unable to learn what occurred at the hearing before press time.
On his LinkedIn page, Haldeman describes himself as a "CEO, CMO, Innovator, Mentor." He is chief executive officer and president of Code-N, a Menlo Park-based "next-generation cloud computing company," according to the company's website.
Sheriff's investigators "believe there are potentially more victims out there and encourage anyone who had any contact, with the suspect, allowed him to be around their child/children, or believe anyone may have been victimized" to contact Detective Fava at 650-363-4192 or firstname.lastname@example.org; or Detective Derespini at 650-363-4055 or email@example.com, a Sheriff's Office press release says.
