The company will do all it can to prevent content like Stephens' post, Chief Executive Mark Zuckerberg told Facebook's annual conference for software developers on Tuesday in San Jose, California.

Facebook on Monday said it would review how it monitors violent footage and other objectionable material in response to the killing after Stephens' post was visible on the social media site for about two hours.

Stephens is not believed to have known Godwin, a retired foundry worker who media reports said spent Easter Sunday morning with his son and daughter-in-law before he was killed.

Beech Brook, a behavioral health facility in a Cleveland suburb where Stephens had worked since 2008, said in a statement on Tuesday that Stephens had cleared an extensive background check.
