The man who killed a Washington, D.C. yoga instructor who served as Jenna Dewan Tatum’s stand-in for the film “Step Up” was sentenced to 30 years in prison for the crime on Friday, ABC affiliate WJLA reports.

Duane Johnson, also known as Adrian Duane Johnson, pleaded guilty to first degree felony murder in connection to the Christmas 2016 killing of Tricia McCauley in September.

The U.S. attorney’s office said that McCauley left her Washington, D.C., home on Dec. 25, 2016 en route to a friend’s holiday party when she encountered Johnson, who entered her car and sexually assaulted her. McCauley attempted to fight Johnson off by kicking and punching him. Johnson eventually strangled Johnson to death with a scarf she was wearing.

Following McCauley’s death, Johnson put her body in the back seat of her car.

In the hours following her disappearance, police released a photo of a man they believed was driving McCauley’s car. Someone called police saying they saw McCauley’s car on Monday night, upon which authorities found the man inside a nearby CVS. The suspect gave them the keys. Upon searching the car, police found McCauley’s body, the Associated Press reported at the time.

Outside of her work on “Step Up,” which starred Channing Tatum, McCauley also acted in two short films, “The Paper Girl” and “Never Dream: The Beginning.”
