A former Navy detective and El Cajon police officer sentenced earlier this year for using excessive force on a detained sailor at Naval Base San Diego pleaded guilty Thursday in San Diego federal court to a charge of conspiracy to distribute child sex abuse material. The court documents indicated that law enforcement agents believed the discussed abuse actually occurred and that LaRoche shared the files. The business would solicit requests for specific material from some users and then commission other users to create that material. LaRoche allegedly sought payment for creating child sex abuse material, a plan that allegedly almost backfired when the business discovered his real identity and threatened to blackmail him. The conspiracy count carries a mandatory minimum sentence of five years in prison and a maximum sentence of 20 years.
