What they're saying:
"Decades ago, this defendant went to prison for sexually abusing a child. When given a second chance, he chose not to change—instead, he went on to sexually abuse two more children, this time within his own family," Senior Deputy District Attorney Ben Moreno said.
"This sentence reflects the severe and lasting harm he caused and sends a clear message that child sexual abuse will not be tolerated, especially by repeat offenders."
