According to court records and information provided by the Solano County Sheriff’s Office,a 12-year-old victim and her mother were living with Dennis Vongsa in Rio Vista in October of 2021. After several years of sexual abuse by Vongsa, the girl left her home during the night and ran to a neighbor’s home for help.

The neighbor then called the Rio Vista Police Department, a city contracted with the Sheriff’s Office. Officers responded and an investigation was launched with help from Sheriff investigators.

After an interview with the victim, where several items of evidence were discovered to have been collected by the victim herself, detectives developed enough evidence to arrest Vongsa.

The abuse began in 2017 and continued until October 2021, when the victim decided to seek help and left her own home to do so.

The case was investigated by Solano County Sheriff’s Office Deputy Danny Schilling. Deputy District Attorney Shelly Moore led the prosecution. Chief Deputy Public Defender Felicia Carrington represented Vongsa.
