An 18-year veteran of the Hayward police department is facing prison time after admitting to having oral sex with two boys.
Forty-one-year-old Jeff Cristofani will register as a sex offender after pleading no contest to two counts of oral copulation with a minor.
The plea means he could be sentenced to more than two years in prison.
Cristofani acknowledged he had oral sex with two boys -- one in December 2001 and another in April 1997.
In exchange for his plea prosecutors dropped three other charges.
Prosecutors alleged that Cristofani also threatened a 17-year-old boy against telling anyone about what happened.
The sex crimes came to light after one of the victims agreed to secretly record a meeting with Cristofani.
