Logan's mother, Marlyse Williams, told Tri-City News the family is "absolutely devastated" by her son's passing. "I am not able to hug my parents who lost their only grandchild," she said. "It's hard... With his talent and gorgeous looks, Logan had the potential to be a huge star."

The Flash lead Grant Gustin took to Instagram to eulogize Williams as well, sharing a picture of himself, Williams and fellow Flash star Jesse L. Martin. "Just hearing the devastating news that Logan Williams has passed away suddenly," Gustin wrote. "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. 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."
