No one expected Facebook users to use the live video streaming feature to broadcast brutal attacks and killings, but that's exactly what has happened in the last few years.
From gang-related shootings to sexual assault, many used the platform to gain a sense of instant notoriety and show off their crimes to an audience. Other times, the attacks were coincidentally caught on social media. See some of the most heinous crimes that have been live streamed on social media.
A 2017 video streamed on Facebook Live showed 19-year-old Serena McKay being brutally beaten to death by two other teenagers. The video remained on the social networking site for four hours before it was removed.

The teens' principal believes the murder was drug-related. Two suspects face murder charges.
An 18-year-old Chicago man with "mental health challenges" was tortured with a knife and verbally abused by four suspects while the attack was broadcasted on Facebook Live.

At one point, the video live stream had more than 16,000 viewers, many of which interacted with the attackers.
The young man later escaped and the four were arrested by police.
After an argument with his girlfriend, Cleveland man Steve Stephens published to Facebook a video of him approaching and fatally shooting an innocent elderly man while walking along 93rd Street in the large Ohio city.

In a subsequent live video, Stephens explained how he was going on a "massacre" and claimed to have killed 13 others. After a three-day manhunt, Stephens shot himself in Erie, Pennsylvania before police could get to him.
