9-year-old dies in viral 'blackout challenge' horror as parents demand accountability: 'It's life or death'

"She goes out to play like she always does, out in the yard. I noticed it's kind of quiet - quieter than it should've been," her father, Curtis Blackwell, told the outlet as he described the moment he found his daughter.  

"Then I saw her kind of around the corner that goes to the carport, saw her hair. I said, 'JackLynn!' I thought she was bending over playing 'cause she was always in that area playing, but she wasn't playing."

The father quickly went to check on his daughter, who was found motionless with a cord wrapped around her neck.

"I tried to do everything I could to save her," Curtis Blackwell told the outlet. "I got her off the cord. I tried to give her CPR until the first responders got there. It was the most terrifying, shocking thing I've ever seen."

"It was horrible to see my daughter in such a vulnerable state because of something so senseless."

"It's not a joke, it's not a game, it's life and death," Curtis Blackwell said, according to the outlet.

"Most of the kids are like 9 years old to 14 years old. A lot of kids her age, their brains aren't fully developed, and they are very easily influenced."

Approximately 80 children have died from the online trend, according to the CDC, CBS reported.

Several social media companies are reportedly blocking videos related to the deadly challenge or issuing warnings to viewers who search for related keywords.

However, the warnings are too late for JackLynn's grieving parents, who are looking to hold social media companies accountable for the videos posted to their platforms. 

"You could check on your kid, it could be kid-friendly videos, and then three minutes later it could be totally something dark because of the algorithms they start creating," Curtis Blackwell told CBS. "There's too many of these kids lost for these companies not to be held accountable in my eyes."
