McKinney police searched Dr. David Russell's chiropractic office for more than four hours.
The attorney for a McKinney chiropractor accused of sexually assaulting two teenage girls blasted the investigation on Thursday.
Chiropractor Dr. David Russell is charged with two counts of aggravated sexual assault of a child.
Raf De La Garza said it is "impossible" for what the teenagers told police officers to have happened.
"The only logical conclusion one can come up with is someone out there has a personal vendetta against him and is trying to do whatever they can to harm him," he said.
Both girls told investigators that Russell made sexually suggestive comments and touched them inappropriately while treating them for groin injuries.
De La Garza said the older of the victims, a 16-year-old who is now 18, is fabricating her story.
"I think when the day of light shows on her, the public will see how this young lady tends to exaggerate," he said. "And I think if you look at her reputation in the community for being credible, for being a truth teller, I think at the end of the day, you'll see that she doesn't have a reputation for being truthful."
The girl said the assaults happened on numerous occasions when she went to Russell for treatment at his clinic on Virginia Parkway.
She said he manually penetrated her and told her it was the only way to fix her groin muscle, according to court documents. He also made comments about her bras and breasts, she told police.
The younger victim, a 13-year-old, said Russell fondled her genitals.
De La Garza said the 13-year-old may be mistaken about what happened because her treatment was near her genitals.
"The question is, if you touch someone, 'Are you doing it for your own sexual gratification?' And you're not," he said. "This was totally professional."
Russell told police that he likely touched the girls' genitals while working and that it was possible he placed his hands on their skin inside their underwear for traction purposes, according to court documents.
The university Russell graduated from told the detective investigating the case that it does not teach any procedure that would require a chiropractor to touch a female patient's genitals. The chiropractic school also said students are taught how to prevent touching a patient's genitals during soft tissue massages.
De La Garza said Russell's office is wide open and visible by staff and that parents are allowed to watch treatment sessions.
He theorized that his client is caught in the middle of a fight between the Taylor Dance Center, where he volunteered and the victims take classes, and a former employee who was fired and now works for a different dance studio.
The former instructor told NBC 5 she called police after the older victim came to her with concerns about her treatment for her groin injuries.
"As a teacher and an adult, it's my obligation to report things that don't sound right to me, and it certainly didn't sound right," she said.
McKinney police searched Russell's chiropractic office for more than four hours Thursday evening. Officers took file cabinets, storage boxes and computers.
Police said the search was not related to the two cases that have already been filed against Russell but was about other possible cases.
Investigators said Wednesday they were talking with two additional possible victims.
Russell Chiropractic has closed indefinitely. Its website was shut down at least as early as Wednesday night.
