The first time Jacob Mark Duenas was convicted of molesting a minor, he was a California Highway Patrol officer, so the judge gave him probation after he pleaded no contest to molesting a 13-year-old girl and a 14-year-old girl.
It was 2008 and Duenas was fired from his job and forced to register as a sex offender.
In 2014, he was arrested again, this time for molesting a 10-year-old boy. Duenas pleaded no contest again and the judge sentenced him to six months in jail with five months probation.
On Monday, the 37-year-old man was convicted of repeatedly raping a fourth child, this time an 8-year-old boy back in 2000 when he was trying to become a police officer.
The victim testified that he did not tell anybody about the rapes for years, but it changed his personality, leaving him angry and isolated.
