PHILADELPHIA (WPVI) -- A nationwide manhunt ended Tuesday when Facebook murder suspect Steve Stephens killed himself.
Authorities launched a search for the 37-year-old after he posted video of himself shooting a 74-year-old grandfather on his Facebook page.
Acting on a tip, Pennsylvania police located his vehicle and pursued Stephens.
He shot himself in the head after officers disabled his car.
The video of the murder was on Stephens' Facebook page for several hours before Facebook deleted it.
CEO Mark Zuckerberg told attendees at the company's developer conference it will work harder to stop similar content.
"We're also going to work on building common ground. Not just getting more different opinions out there, but also helping to bring people closer together. And there's a lot to do here. We have a full roadmap of products to help build groups and community, help build a more informed society, help keep our communities safe. And we have a lot more to do here and were reminded of this this week by the tragedy in Cleveland. Our hearts go out to the family and friends of Robert Godwin Sr. and we have a lot of work and we will keep doing all we can to prevent tragedies like this from happening," Zuckerberg said.
Facebook also issued a statement saying that it is reviewing its reporting flows.
The company says that will make it easier for people to report questionable content.
