Two Sacramento men indicted on suspicion of child porn offenses

Two Sacramento men were independently indicted by federal grand juries Thursday on suspicion of crimes related to the sexual exploitation of minors.

Mark Richards, 48, was charged with advertising and distributing child pornography, while registered sex offender David Seilheimer, 50, was charged with receiving and possessing child pornography. Both are being held in Sacramento County Main Jail without bail.

According to court documents, undercover officers outside California allegedly received child pornography from Richards via a password-protected, peer-to-peer file sharing network on Jan. 7 and Jan. 11.

Seilheimer allegedly downloaded and shared videos and images of prepubescent children engaged in sexual activity between May 2015 and Feb. 7, 2018, when he was arrested by Sacramento County sheriff's deputies.

Richards' case is the product of an FBI investigation, while Seilheimer's came to as a result of the Sheriff's Department's Internet Crimes Against Children Task Force. Richards previously pleaded guilty to misdemeanor child neglect in 1990, Sacramento County Superior Court records show.

If convicted, Richards faces up to 30 years in prison plus $250,000 and 20 years for each count of distributing child pornography. Seilheimer faces a maximum penalty of 40 years in prison and a $250,000 fine.
