A Texas man pleaded guilty to kidnapping a 13-year-old girl who was rescued in California after an observant passerby saw her hold up a "Help Me!" sign in a parked car.

According to a statement from the U.S. Attorney’s Office in the Central District of California, Steven Robert Sablan, 62, of Cleburne, Texas, pled guilty.

The 62-year-old admitted that he had sexually assaulted the 13-year-old girl after kidnapping her.

Sablan drove the Texas teenager to California after kidnapping her on July 6, 2023 in San Antonio.
