Chesco ‘child predator’ gets 100 years for state’s largest-ever child porn stash

Lawrence Jamieson, the scion of a respected Main Line family, was actually a “child predator,” Philly federal prosecutors said before he was sentenced to 100 years in prison for sex crimes and possession of child pornography.

Lawrence, also known as “Larry,” Jamieson, Jr., 59, of Malvern, Pa. pleaded guilty in September 2017 to charges related to his stash of some 14.4 million child pornography images, collected off the internet over the 15 years on thousands of DVDs, thumb drives and other digital storage devices.

The collection was believed to be the largest discovered by law enforcement in Pennsylvania history. It contained “some of the most demented images imaginable of toddlers and infants being sexually assaulted by adult men and women, and in some cases, by animals,” federal prosecutors said.

But his crimes didn’t come to light until he and an accomplice undertook to manipulate an underage girl with learning disabilities and mental health issues into performing sex acts with both men, which they recorded and distributed online.

“[Lawrence Jamieson] is the worst of the worst type of criminal – a child predator who derives satisfaction from abusing society’s must vulnerable members,” U.S. Attorney William McSwain said in a statement announcing the sentence.  “The details in this case are horrific. … He concocted and carried out a plan to sexually abuse a child within his care – someone he knew was susceptible to his influence.”

Lawrence Jamieson is the son of a well-known family in Willistown, Pa. His father was Lawrence Jamieson, a former member of Downingtown Borough Council who worked as an insurance agent at Massachusetts Life Insurance Co. in Paoli, Pa., and died in 2010. Jamieson’s mother Kathleen Casey Jamieson is the owner of Mock Fox Interiors, an interior design business in Haverford, Pa.

Lawrence Jamieson and his twisted plot

Jamieson, who reportedly worked as a private contractor, was arrested in August 2016 by Chester County authorities after the victimization of the underage girl by Jamieson and accomplice John Christopher Brown of Norristown, Pa., came to light.

The victim has not been identified, but federal prosecutors said she was “in his care” and “well acquainted” with Lawrence Jamieson, who knew she was on the Autism spectrum, had learning disabilities and mental health issues. According to the Chester County Daily Local News, when the victim was aged 15, in February 2015, Jamieson plotted to introduce her to Brown, then 23, who he claimed was 17 and also a student. Jamieson even devised a fake age and birthdate for Brown, as well as a backstory that he attended a cyber school.

John Christopher Brown changed his appearance to look younger, prosecutors said. (See comparison image above).

Over the next 18 months, Brown had several sexual encounters with the victim, aged 15 and 16, which he photographed, recorded and then shared with Jamieson, who distributed them online.

“He [Jamieson] targeted this underage girl by first recruiting another adult male to pose as a teenaged boy so that they could dupe the victim into believing he was her boyfriend and gain her trust,” federal prosecutors said.

The victim’s mother eventually discovered the affair. The victim told authorities during an interview that she and Brown were dating and that he was “everything she ever wanted in a boyfriend,” according to the Cheso Daily Local.

But she was unaware her “boyfriend” and his accomplice had been using her to create illegal child pornography – and after police raided Jamieson’s home, they found his massive child porn stash.

Brown’s sentence is still pending.

In addition to 100 years in prison, Jamieson was ordered to never contact the victim or her family again.

“Predators, take note,” McSwain warned in a statement. “No matter who you are or where you come from, we will hunt you down, prosecute you, and put you in a jail cell for a very long time.”
