Their teenage children died by suicide. Now these families want to hold social media companies accountable

Christopher James Dawley, known as CJ to his friends and family, was 14 years old when he signed up for Facebook, Instagram and Snapchat. Like many teenagers, he documented his life on those platforms.

CJ worked as a busboy at Texas Roadhouse in Kenosha, Wisconsin. He loved playing golf, watching "Doctor Who" and was highly sought after by top-tier colleges. "His counselor said he could get a free ride anywhere he wanted to go," his mother Donna Dawley told CNN Business during a recent interview at the family's home.

But throughout high school, he developed what his parents felt was an addiction to social media. By his senior year, "he couldn't stop looking at his phone," she said. He often stayed up until 3 a.m. on Instagram messaging with others, sometimes swapping nude photos, his mother said. He became sleep deprived and obsessed with his body image.
