Former Sebastopol Mayor Robert Jacob has pleaded no contest to six counts of child sex crimes. The 45-year-old was supposed to begin a jury trial today, but reached a plea deal with prosecutors instead. Jacob will be sentenced to seven years in prison and must register as a sex offender for the rest of his life. During a court hearing last March, the victim testified that he met Jacob through the Grindr dating app. He said Jacob knew he was under aged, but touched him sexually, sent him nude photos, and invited unknown men to have sex with him.
