The stuntwoman who died on the set of Deadpool 2 Monday has been identified.

Joi “SJ” Harris, who billed herself as the first African-American female road racer, died while performing a motorcycle stunt in Vancouver, Canada, media reports have confirmed.

The Brooklyn, New York native was an advocate for women of color in the road racing game, and promoted herself as “the first licensed African American women in U.S. history to actively compete in sanctioned motorcycle road racing events.”

On Friday, Harris updated her Facebook with a selfie, writing, “EVERYTHING FOR A REASON. #staythecourse.”

“Today, we tragically lost a member of our crew while filming Deadpool,” the film’s star, Ryan Reynolds tweeted. “We’re heartbroken, shocked and devastated… but recognize nothing can come close to the grief and inexplicable pain her family and loved ones must feel in this moment. My heart pours out to them — along with each and every person she touched in this world.”

“I’m deeply saddened by the loss of one of our stunt performers today,” Deadpool 2 director David Leitch said in a statement to EW and PEOPLE. “No words can express how I and the rest of the Deadpool 2 crew feel about this tragedy. Our thoughts are with her family, friends and loves ones in this difficult time.”

This was Harris’s first film as a stunt performer, according to Deadline, which reported that she was not wearing a helmet during the scene because her character does not wear a helmet.
