Son T. Nguyen, 71, of Richardson, was sentenced to 29 years in prison without parole for Aggravated Sexual Assault of a Child Under Six (6), announced
Collin County District Attorney Greg Willis.
On Aug. 29, 2015, Nguyen sexually assaulted a 4-year-old girl who was in his girlfriend's care. When the little girl's mother picked her up from the babysitter's house in the evening, the girl immediately told her mother that her private part hurt. When asked why, the little girl described what Nguyen had done.
The girl's mother immediately took her daughter to the pediatrician and soon thereafter to the REACH clinic for a sexual assault exam. Dr.
Kristin Reeder conducted the medical exam and collected DNA evidence and clothing from the girl. DNA analysis results showed that Nguyen could not be excluded as a match for the DNA collected from the girl and her clothing.
Plano Police Department Detective
Danny Bryeans lead the criminal investigation. Days after the sexual assault, Lisa Martinez, from the Collin County Children's Advocacy Center, conducted two forensic interviews with the girl during which she was able to describe what Nguyen had done to her.
The jury returned a guilty verdict for Aggravated Sexual Assault of a Child Under (6) before sentencing Nguyen to 29 years in prison without parole.
Richard Davis presided over the jury trial. Assistant District Attorneys
Sarah Preston and
Geeta Singletary prosecuted the case, assisted by District Attorney Investigator
