Actress Lisa Sheridan’s Cause of Death Revealed

“Halt and Catch Fire” star Lisa Sheridan passed away on February 25, and now her cause of death has been revealed.

In a New Orleans Coroner report obtained by RadarOnline.com, it lists her cause of death as “complications of chronic alcoholism” and manner as “natural.”

The autopsy also stated she had a “reported history of benzodiazepine abuse." The medication is typically prescribed for anxiety and insomnia.

Sheridan also suffered a remote brain injury related to a fall, according to the documents.

Other findings included “hyperinflated lungs” and a cyst on her right ovary.

The 44-year-old was found dead in her New Orleans apartment. At the time, there were rumors she may have taken her own life, but her manager Mitch Clem told People the claims were untrue.

“The family has unequivocally confirmed that this is not a suicide. Any suggestion to the contrary is absolutely, 100% unfounded,” he said.

After she passed away, friends and co-workers remembered her on social media.

Sheridan's friend Donna D'Errico mourned her death, writing on Facebook, “I just received news that my dear friend, actress Lisa Sheridan, has passed away. She was found Monday morning. I am sitting here stunned. Lisa and I filmed a movie together 5 years ago and became very close on set and remained close friends after filming ended.”

“I am devastated by this loss. I had just spoken with her and everything seemed great and she seemed happy and in good spirits. Everyone who knew her loved and adored her. Goodbye and goodnight sweet angel…I will miss you terribly,” D'Errico continued. “Please send up prayers for her family.”

Filmmaker and friend Michael Dunaway, who she called “Big Brother,” added on Instagram, “She was beautiful, obviously, and an immensely talented actor, and a wonderful friend, but more than anything she really did radiate this impossibly bright energy and life. Even in her dark moments. And she had plenty of those, especially over the last few years. During these later years she took to telling me, 'You're the greatest big brother a girl could ever have.' It was how we ended each conversation. I treasured it then, and I treasure it even more now knowing I'll never hear it again, this side of the river. So good night, my sweet little sister.”
