The heartbreaking news was confirmed by a few of his co-stars on Friday, including Grant Gustin, who plays Barry Allen on The Flash. Williams portrayed the younger version of his character on the popular CW series.
"Just hearing the devastating news that Logan Williams has passed away suddenly. This picture was early in the filming of The Flash pilot episode back in 2014. I was so impressed by not only Logan’s talent but his professionalism on set," wrote Gustin. "My thoughts and prayers will be with him and his family during what is I’m sure an unimaginably difficult time for them. Please keep Logan and his family in your thoughts and prayers during what has been a strange and trying time for us all. Sending love to everyone. ❤️"

"He was just shy of 17 and had what I'm sure would have been a very bright future ahead of him. I hope you'll join me in sending virtual love & support to Logan’s family & friends during this very painful time. 💔 #Hearties."

According to Tri-City News, Williams' mother, Marlyse, is "absolutely devastated," and says that the family cannot even grieve together because of mandatory social distancing due to the coronavirus pandemic.
"I am not able to hug my parents who lost their only grandchild," she told the outlet. "It's hard."
"With his talent and gorgeous looks, Logan had the potential to be a huge star," she added.
Williams' mother confirmed, in an interview with New York Post on May 15, that preliminary toxicology tests showed her son died of a Fentanyl overdose. According to the actor's mother, her son had struggled with substance abuse for three years.
In addition to his mother, Williams is survived by his father, Clive, as well as grandparents, aunts and uncles.
