On Tuesday September 1st, 2015, the Contra Costa County Internet Crimes Against Children Task Force arrested 66-year-old Walnut Creek resident Marshall Pfeiffer for possession of child pornography, a violation of California Penal Code section 311.11(a).

The arrest stems from an investigation conducted by members of the task force which consists of detectives from the Walnut Creek, Martinez, Pittsburg, Brentwood, Moraga, Concord, Pleasant Hill and San Ramon police departments, along with investigators from the Sheriff’s Office, Probation and the District Attorney’s Office, and with assistance from federal law enforcement.

On September 1st, 2015, the task force executed a search warrant at Pfeiffer’s home in the 100 block of El Camino Corto in Walnut Creek. A search of the residence yielded files of child pornography stored on a computer. As a result of the search warrant, Pfeiffer was arrested and booked at the Martinez detention facility on suspicion of possessing child pornography. He is being held on $20,000 bail.

Pfeiffer recently retired from the Acalanes Union High School District where he was a teacher at Acalanes High School in Lafayette. Pfeiffer has been cooperative in the investigation and there has been no evidence to suggest any illegal activity with respect to his career as a teacher. School administrators have been advised of the arrest.

Anyone with additional pertinent information should contact the Acalanes Union High School District or the Lafayette Police Department. Any questions regarding the arrest can be addressed to Lieutenant Lanny Edwards at the Walnut Creek Police Department at 925-943-5883.

  1. Too early in the legal process of course but it would be nice to know what sort of evidence they must have against him. And is there data on the prevalence of this sort of offender within local school districts. Are they drawn to the profession or is the percentage the same for other professions. This is very tough to digest and my thoughts are with those affected by this horrific crime.

  2. Pretty much every parent’s nightmare. You just never know what is going through someone’s mind or what drives them. Happy to hear no students were involved.
