• Logan Williams died of fentanyl overdose
  • Marlyse Williams admitted her son Logan struggled with addiction for three years
  • "The Flash" star died days before his 17th birthday

Logan Williams struggled with addiction before his passing, according to his mom.

On April 6, many were shocked to hear the news that Williams had passed away. He was only 16 years old when he died four days prior the reports surfaced. Many believed he had a bright future ahead of him.

“Logan was an exceptional talent, with a kind heart, and an infectious spirit. We will all miss him tremendously. Our thoughts and prayers are with his family and loved ones,” his agent Michelle Gauvin told People at the time.

Williams’ family didn’t disclose the cause of his death. However, in a recent interview with New York Post, his mom, Marlyse Williams revealed that her son died of fentanyl overdose.

According to Marlyse, “The Flash” star struggled with addiction for three years. The family kept it a secret, but this time, she wants to help bring awareness to the opioid addiction epidemic.

“His death is not going to be in vain,” Marlyse said. “He’s going to help a lot of people down the road.”

According to Marlyse, she didn’t know when her son started taking fentanyl. Also, as his addiction progressed, he was in complete denial about it because he felt too ashamed to share it.

Marlyse tried to help her son address his addiction. She sent him to an expensive treatment center in the U.S. and to a British Columbia facility for a month.

“I did everything humanly possible — everything a mother could do. I did everything but handcuff him to me to try to keep him safe,” she added.

Marlyse also explained why the family decided to keep Williams’ addiction a secret. According to her, he wanted to get back to Hollywood and they didn’t want people to know because of potential judgment, criticism and embarrassment.

Also, Williams himself was determined to get back on track.

“He said to me, ‘Mom, I’m gonna get clean. I’m going to get better. And I want my new life to start.’ I just know the last thing we said to each other was, ‘I love you,’” Marlyse recalled.

Williams died days before his 17th birthday. Aside from his stint on CW’s “The Flash,” he also appeared on “When Calls the Heart,” “Supernatural” and “The Whispers.”
