Investigators said when the teen posted an ad online seeking a modeling opportunity, Deshpande responded as a man named "Devin" and convinced the teen to send nude photos.
The suspect then told the teen he would post her pictures on the "dark web" if she didn't continue.
Prosecutors said Deshpande then traveled to Orlando in September 2017 posing as a friend of "Devin." He then took the girl to a hotel and recorded himself sexually assaulting her, according to investigators.
Officials said he flew back to Orlando four more times over seven months to commit the crimes again.
Deshpande was eventually captured by officials through a security area at Orlando International Airport as he was on his way to meet the victim again.
Following his arrest, investigators said Deshpande asked a fellow inmate to kidnap and kill the victim.
