Party planner DJ, 35, with tummy fetish is charged with sexual assault after faking elaborate medical study to feel and photograph female employee for a year: Investigators find 1,000 photos and videos of other victims

A party planner DJ has been charged with sexual assault after he faked a medical study to touch and photograph women for a year.

Brian Casella, 35, from Bethel, Connecticut, faces a fourth-degree charge of sexual assault after he allegedly caressed and pictured his worker's stomach for a year.

Casella owns a business called Vivid Events that provides DJ entertainment, lightings and other services for weddings and parties. 

A female employee in August alleged Casella approached her with a fake clinical trial and then sexually assaulted her.

Casella described the study as 'sending sounds of the victim's digestive system in order to ascertain the nature of her food sensitivity'. 

The DJ allegedly offered thousands of dollars to victims and said the monetary compensation was from the company that operates the study. 

 'Casella stated that throughout his life he's found ways to satisfy his fetish,' a criminal complaint obtained by NBC states. 

He 'told the victim that she could not tell her co-workers because they would be jealous of the extra money she was making. 

'Casella went on to also tell the victim that she could not tell Casella's wife about the sessions,' the arrest affidavit notes. 

Authorities said the alleged medical study went on for nearly a year, in which Casella collected more than 1,000 photos and videos of victims in a hard drive. 

The so-called 'tests' took place on an office floor at Vivid Events, located on Federal Road, Brookfield in Connecticut. 

The alleged study started by Casella using a stethoscope to listen to the victim's belly, according to the complaint. 

Casella then gave up on the tool, instead placed his ear on the victim's stomach to 'hear her digestive sounds with his ears better than a stethoscope.' 

'As the sessions went by, Casella grew more comfortable with the victim's body and began to lift clothing up on his own in order to check certain areas and touch other areas,' the complaint states. 

Casella came up with more outrageous requests, including encouraging the victim to take sleeping pills as part of 'a bigger study.'  

The woman said yes, but she secretly took only half of the pill and acted like she was sleeping. 

'She was afraid if she was asleep something would happen, and things did not feel right to her,' the complaint reads. 

 The victim alleges that she was laying on the floor pretending to be asleep for hours  in scrub-style pants and with only tape covering her nipples while her boss took pictures of her.

After she refused to take sleeping pills again, Casella allegedly agreed but tied her down with the company's zip ties to restrain her from moving during a test.   

Casella also reportedly used various tools, including electrically conductive patches and sonograms, to make the study appear more realistic. 

He allegedly placed those objects near the victim's genitals and took advantage of her.  

The study ended when her boss, on the last session, wiped her vagina, cleaning up gel left from a sonogram test, the victim said. 

The business owner would turn off all surveillance cameras in the office during those tests, the victim claimed. A gastroenterologist told police that they were 'unaware of any company which would hire or pay a civilian with no medical training or experience, to conduct medical testing.'

Police then discovered more than 1,000 videos and photos of multiple victims during a search of Casella's truck and office. 

Casella turned himself in to police and was arrested last Friday. 

He allegedly admitted to have acquired most of his victims by posting ads on Craiglist, which the party planner said he had been doing 'for years.'

'Casella admitted that he was lying to people while conducting such examinations, and stated he knew it was wrong,' according to documents.

'Casella stated that ever since he was young he's had a fetish, which he's never really addressed, and it has been with him his whole life,' the complaint reads. 

He posted a $10,000 bond and is due in court on November 29.

State police believe more victims have been violated during his fake medical study, and is asking anyone with knowledge to come forward.
