SANTA CLARA — The chief financial officer of a center that serves some of Santa Clara County’s most vulnerable youths was arrested Thursday after he was reportedly found with child pornography at his home, authorities said.

David Bruce Lang, 63, of Santa Clara, was booked at the Main Jail in San Jose on a misdemeanor charge of possessing child pornography after Santa Clara police, along with the Silicon Valley Internet Crimes Against Children and the Sexual Assault Felony Enforcement task forces, served a search warrant around 7 a.m. at his home on Bret Harte Court.

Authorities said Lang has been associated with the Bill Wilson Center in Santa Clara since 2004. The center provides services for or performs outreach to at least 2,500 runaways and homeless youths each year.

Lang also served as an assistant scoutmaster for a Sunnyvale Boy Scout troop in the 1970s.

Child pornography featuring “mostly boys” was found on a computer at Lang’s home, said Santa Clara police Lt. Dan Moreno. A preliminary review indicated that the children depicted in the images were not associated with the center, Moreno added.

Moreno said authorities routinely investigate residents who trade child pornography online and that’s likely how Lang came to their attention.

“We were very concerned,” said Moreno, referring to Lang’s position as the center’s chief financial officer. “As soon as it came to our attention, we moved very quickly.”

The center confirmed Lang’s arrest in an emailed statement Thursday afternoon. He has been suspended from his post pending further investigation.

“BWC is cooperating fully with the police in this matter,” the statement said.

Lang served as a board member before taking on the role of chief financial officer five years ago and did not have contact with youths at the center, according to Robin Reynolds, a spokesman for the center.

All employees are required to undergo a fingerprint background check, he said.

The Bill Wilson Center was founded in 1973 by its namesake, a former Santa Clara councilman who worked with troubled youths. It initially combined counseling for secondary school students with a family therapy program. Today, the center provides services to more than 5,100 children, youths, young adults and families through housing, education, counseling and advocacy programs, according to its website.

Lang’s bail was set at just $5,000, said Moreno, adding that the alleged criminal offense appeared to be his first.

The investigation into Lang is continuing and anyone with information can contact Santa Clara police Detective Frank Hagg at 408-615-4821.
