A former Marin youth football coach arrested in a child pornography investigation was arraigned Tuesday on two felony counts.

John Baptist deLorimier, 72, of Bolinas is charged with possession of child porn and sending obscene material depicting a minor.

DeLorimier, who remains in custody in lieu of $1 million bail, appeared in court with a private defense attorney but delayed entering a plea. Judge Paul Haakenson ordered him to return on Jan. 22 for further proceedings.

The defense attorney, Douglas Horngrad, said after the arraignment that deLorimier will plead not guilty, but he declined to comment on the allegations because he had just received the investigative reports.

The Marin County Sheriff’s Office arrested deLorimier at his home on Friday. The department opened an investigation last month after receiving information from the National Center for Missing and Exploited Children, which got a hotline tip about potential child porn transmissions.

Investigators traced the transmissions to a home in Bolinas and identified deLorimier as the suspect, the sheriff’s department said. Deputies took deLorimier in for booking and seized electronic equipment into evidence.

The sheriff’s department said investigators do not suspect any children depicted in the images are Marin residents.

Sheriff’s Sgt. Brenton Schneider declined to release additional information about the investigation on Tuesday.

DeLorimier, an artist and graphic designer, is a former assistant coach for the Tamalpais High School and Marin Catholic High School football programs. He was also a former volunteer coach for Southern Marin Youth Football.

The Vallejo Times-Herald reported that deLorimier is a teacher at Mare Island Technology Academy High School. Matt Smith, superintendent of Griffin Technology Academies, a charter network which includes two high schools and two middle schools, said deLorimier was also the yearbook teacher, the newspaper reported.

“At no time were police on any GTA campus related to this matter, nor is it thought that any GTA students or equipment were involved in the commission of his activities,” Smith wrote in an email sent to parents on Friday. “Moreover, note that there were no images of any GTA students, and that the material in his possession were so-called ‘known images’ that, sadly, are frequently circulated on the internet.”

Smith also said that deLorimier “will not be returning to any GTA school, in any capacity, ever.”
