A Parkville man who filmed underage girls with a so-called “x-ray lens” will be spending lots of time behind bars. 

A U.S. District Judge on Friday sentenced Ruben Uy Lim, 53, of Parkville, Maryland, to 10 years in prison, followed by 20 years of supervised release for receipt of child pornography. In addition, Lim has admitted taking hundreds of videos of underage girls at swim meets, using a filter that allowed the camera to see through certain fabrics, including bathing suits. The judge ordered that, upon his release from prison, Lim must register as a sex offender in the place where he resides, where he is an employee, and where he is a student, under the Sex Offender Registration and Notification Act (SORNA).

According to his plea agreement, on November 17, 2015, Baltimore County Police detectives executed a search warrant at Lim’s residence and recovered electronic devices, including a hard drive. A subsequent forensic examination of the hard drive revealed images and video files depicting prepubescent girls engaged in sexual acts, which had been received over the internet.
In addition, law enforcement recovered six video cameras and computer discs which contained hundreds of homemade videos dating back to 2004, which were taken at swim meets, on beaches and at water parks. Lim took the videos using a filter that attached to the camera’s lens and allowed the camera to see through certain fabrics, including bathing suits. Lim filmed middle and high school aged girls in such a way that their breasts and vaginal areas were visible in the recordings. In the majority of the videos, Lim focused on the pubic area of the female swimmers. Lim admitted that he traveled to swim meets around the country for the sole purpose of recording children using the special camera lens, which Lim referred to as the “X-Ray lens.”
