Taking the stage one hour after suspect Steve Stephens apparently shot and killed himself in Pennsylvania, the Facebook CEO told the crowd of developers, analysts, and reporters that Facebook has more work to do in making its 1.86 billion strong community safer. He shot himself in the head after the vehicle spun and came to a stop, police said.
Steve Stephens, a resident of OH, was charged with aggravated murder for shooting 74-year-old Robert Goodwin on Easter and posting the murder on Facebook.
Facebook said it removed the video of the shooting 23 minutes after learning of it. "I am sorry that all of this has happened".
On Monday evening, Facebook announced that it was launching a review for reporting harmful content following the killing.
The FBI had put Stephens on its Most Wanted list, and authorities were offering up to $50,000 in rewards for information leading to his capture.
In a separate video, Stephens claimed to have killed more than a dozen other people.
"I feel bad; the last thing he would have said is my name and he didn't know me or why he was saying", Lane told the sisters.

State television showed what appeared to be several KN-08 intercontinental missiles rolled out on trucks at the parade. An official from South Korea's Defense Ministry couldn't immediately confirm whether the rocket was a new ICBM.
She said the two had dated for a while and even looked at engagement rings at one point.
Nearly 400 tips were called in, Williams said, emphasizing the important role the public played in helping to locate Stephens.
Stephens fled in his vehicle, but was stopped after as short chase.
Law enforcement officials said his cellphone was last tracked Sunday afternoon in Erie, Pennsylvania, about 100 miles (160 kilometers) east of Cleveland.
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.
No one will really know why a man with a spotless record who worked with troubled children would choose such a awful way to end his life.
Can Facebook do anything to keep graphic images from being posted and shared from Facebook Live? Detectives spoke with the suspect on Sunday by cellphone and tried to persuade him to surrender, police said.
