The airman arrested last year on charges that he peeped through his neighbors' windows and filmed them in the nude pleaded guilty Tuesday in a Charleston County court.

Administrative Circuit Judge Roger Young sentenced John Lapinski, 36, of West Palm View Circle in North Charleston to seven counts of voyeurism and will serve three years on each charge. He also was sentenced to 10 years in prison for first-degree assault and battery, according to Assistant Solicitor Timmy Finch.

The sentences run concurrently, Finch said.

Lapinski was a technical sergeant in the Air Force when he was arrested April 10, 2013. He is still employed by the military branch, according to officials with Joint Base Charleston, but was placed in civilian confinement and is not receiving pay.

"The Air Force is monitoring the status of his ongoing criminal case," base officials said in a statement.

The case against Lapinski began when one of his former roommates took his hard drive and handed it to a neighbor. The neighbor called police after finding video of his naked daughter on the device, authorities said.

When questioned by investigators, a woman who lived with Lapinski in 2008 reported that he assaulted her multiple times at two different locations.

Investigators searched Lapinski's home and reportedly found several other videos of women and children. Sixteen videos were found on one Kodak camera alone, police said.

In an arrest affidavit, a detective described video of a woman bent at the waist with her bare buttocks clearly visible in the frame. A child wrapped in a towel was lying on a bed nearby, the detective wrote.

Another video showed a woman making her bed in the nude as a naked child played at the foot of the bed, detectives said. The child appeared to be about 2 years old, according to an affidavit.

Lapinski maneuvered a video camera to peer into the windows and doors of his neighbors to capture the images, authorities said. He reportedly had been compiling the images since March 2010.

Lapinski will be required to register as a sex offender upon his release, Finch said.

"North Charleston detectives did a great job in the investigation of the case. Moreover, the citizens who discovered the materials are to be credited for doing the right thing and notifying law enforcement immediately preventing further offenses," Finch said.
