A Florida man has pleaded guilty to sexually assaulting his girlfriend's 11-year-old daughter after videos of the abuse were found on his phone.

36-year-old Torrie Austin pleaded guilty while at the West Palm Beach federal court on Wednesday.

The girl's mother discovered two videos of her daughter being touched inappropriately on his cellphone as she was searching the device, reported Miami Herald.

It is not known why the woman went through her boyfriend's phone. After coming across the videos, she immediately called the Martin County Sheriff's Office in order to report what she had seen. After obtaining a warrant, detectives also discovered other videos while going through Austin’s phone, Google Drive and Google Photos. In total, there were about six to eight inappropriate videos found on the cellphone device.

The victim's mother was able to identify the man as her boyfriend Austin and had also said that the disturbing footage had been shot in his old home.

Austin would watch over the woman's three children when she was working, which is when the incidents allegedly took place. Austin had also later told authorities when he was arrested that he had been on cocaine at the time he molested the child. He claimed that it was a mistake.

Austin has two children with the 11-year-old's mother and is looking at 15 to 30 years in prison for the production of visual depictions of sexual exploitation of a minor. He has been scheduled to be sentenced in January. He was arrested while he was at his job and is being held in jail with no bail.

Austin was charged with sexual battery of a minor younger than 12 as well as producing porn.

In another similar case, a man from Fort Pierce was recently charged with attempted sexual battery on a person between the ages of 12 and 18. 37-year-old Jeremiah John Kramer was released from the St. Lucie County Jail after posting $75,000 bond. As per an affidavit submitted in December, Kramer had repeatedly touched the teenager inappropriately.
