A registered sex offender charged with sexually assaulting a 14-year-old girl while out on bail in another case accepted a plea deal for eight years in prison, according to court records obtained Tuesday.
J Isaac Gonzalez Sierra, 69, pleaded guilty Monday to failure to comply with registering as a sex offender and three counts of lewd acts on a child 14 or 15 in one case dating back to 2018.
In his other case, Sierra pleaded guilty to two counts of lewd or lascivious acts with a minor under 14 and one count of sexual battery, all felonies.
As part of his plea deal a count of sexual penetration of a child 10 years or younger was dropped along with a sentencing enhancement for committing a secondary offense while out on bail, according to court records.
Sierra sexually assaulted a 9-year-old girl on Sept. 15, 2019, while she was visiting her grandmother’s home, according to police testimony during his preliminary hearing.
The girl’s mother was visiting with her mother elsewhere in the house when the molestation occurred, police said.
Sierra also molested the 30-year-old sister of the girl’s mother, police said. That victim had a mental capacity of a 12-year-old, police said.
Sierra was given credit for 784 days behind bars.
Sierra is accused of molesting another girl in July and May of 2017. She was a friend of one of his relatives, according to testimony in Sierra’s preliminary hearing.
While driving the girl to a grocery store in Westminster, he groped her and kissed her, police testified in the hearing.
Sierra has a prior conviction for sexual battery in 2012, according to court records.
