How can social media prevent posting of violent acts?
Facebook CEO, Mark Zuckerberg says his team will work to keep the world's leading social network from being used to promote acts of murder and brutality.
A man wanted for killing an elderly man, Robert Godwin, in Ohio and then posting a video of the murder on Facebook fatally shot himself after a brief police chase in Pennsylvania.
Steve Stephens, 37, had been the subject of a nationwide manhunt in the wake of Sunday's killing in Cleveland.
The incident was the latest crime posted on Facebook - giving rise to discussions on how videos of this nature can be removed, or prevented from being shared and whether the pros of live-streaming outweigh the cons. It's believed the footage was only taken down two hours later.
Zuckerberg paid tributes to the victim's family.
"Our hearts go out to the family and friends of Robert Godwin, Sr.. We will keep doing all we can to prevent tragedies like this from happening," he said.
In 2015, reporter Alison Parker, 24, was shot dead alongside 27-year-old colleague and cameraman, Adam Ward during a live television report in Virginia.
The suspect and former station employee Vester Flanagan - who was known as Bryce Williams on-air - filmed the incident prior to posting it on Facebook and Twitter.
While 32-year-old Philando Castile was shot and killed by a police officer in Minneapolis after being pulled over for a broken taillight last year.
Castile's girlfriend, Diamond Reynolds, live-streamed the aftermath of the shooting, which shows an officer pointing his gun at her through the window.
