Fresh tributes have emerged for actor Patrick Muldoon, with close friends Denise Richards and her daughter Lola Sheen sharing emotional messages about the Days of Our Lives star following his sudden death.

Muldoon, 57, died on April 13, with his family confirming he had been “suddenly taken from this Earth”.

His death was reportedly the result of a heart attack.

While news of his passing prompted an outpouring from fans and former co‑stars, new statements from Richards — who shared a 36‑year friendship with Muldoon — have been posted in recent days.

Richards said she was “deeply heartbroken and devastated”, describing Muldoon as her “best friend” and “family”.

“You lit up every room you walked into… so talented and most underrated,” she wrote.

“Your laugh, your kindness, your wit, your strength, your loyalty, your passion, and your zest for life… I don’t know what I’m going to do without you here.

“Our memories together are endless. You’ve had my back and protected me more than anyone.”

She said the pair had been each other’s “rock” throughout their adult lives.

“You’re my voice of reason and pillar of strength… I love you so much and miss you dearly.”
