Alex Torres-Lopez, 35, pleaded guilty to one count of first-degree aggravated sexual assault on Thursday.
The Mercer County Prosecutor's Office is recommending Torres-Lopez be sentenced to 20 years in prison without the eligibility for parole under the Jessica Lunsford Act.
He would also be subject to a lifetime of parole and would have to register as a sex offender.
Sentencing is scheduled for Jan. 8, 2027.
According to investigators, Torres-Lopez met the victim on Snapchat and Roblox. He is accused of sexually assaulting her multiple times in the fall of 2025 in Trenton.
He also had the girl send him pornographic images and videos of herself, prosecutors said.
