In a Facebook post shared on April 11, 2026, Lindsey Cooper announced that her sister Dolly Martinez tragically passed away.

One harshly commented on Lindsey’s post and said, “Please be very honest. … She WAS beautiful to you. Enabling her, praising her at 600 pounds like it’s normal, is not a standard we speak highly of. YALL as a family were more ready to enable her, than actually HELP SAVE HER.”
“...Don’t post, ‘she was so beautiful.’ Sis whole heartedly f*** off. You enabled your sister instead of genuinely helping HER,” the same Facebook user continued. “YOU FED HER, instead if counseling her. You said, “f*** it feed into your desires versus helping your health”. I DO NOT want to hear sh*t about how you’re mourning her, when you could’ve HELPED HER.”

Lindsey shared a Facebook post on Sunday, addressing the cruel comments about her sister in the wake of her passing.
“I know many people knew her from a show or TikTok, and that’s okay but please remember, there’s so much more to her than what was seen online or on TV,” she wrote. “She was my sister first.”
The bereaved sister asserted that Dolly deserved peace and kindness.
“To everyone online being cruel and mean and attacking not only dolly who can no longer defend herself but me and my family,” she continued.
“From the bottom of my soul and as disrespectfully as possible f*** all the way off.

The sister had a message for haters commenting on her weight as well.
“Oh and yes for those pointing out how im just as fat or saying I’m the next to go in the family just know I have chronic health problems and mental health issues and I take meds that cause me to gain weight and I’m working on getting the weight off,” she wrote.
“But that’s not for you to point out. Thanks for coming to my ted talk,” she concluded.
