San Bernardino man sentenced to 180 years to life in state prison for sexually assaulting a child


SAN BERNARDINO, Calif.– A San Bernardino man who sexually assaulted a 9-year-old child was sentenced today to 180 years to life in state prison.

Last month, a jury found 39-year-old Daniel Mateen Jr. (pictured above) guilty of one count of Aggravated Sexual Assault of a Child and three counts of Lewd Act Upon A Child.

According to Deputy District Attorney Jane Templeton, who prosecuted the case, the charges stem from multiple events that occurred in 2006.

It wasn’t until the victim was fifteen years old that she finally came forward, fearing that she would have to face the defendant again.

“Thanks to the courage of the young victim in this case, the defendant will be locked away for at least 180 years to life, and never have the chance to harm another child,” said DDA Templeton.

The San Bernardino Police Department was the investigating agency.
