Original story:

Authorities continued their search Monday for a Cleveland man accused of randomly shooting and killing an elderly man on Easter Sunday. Police said the suspect, 37-year-old Steve Stephens, uploaded the video he took of the heinous act to Facebook.

The shooting death of 74-year-old Robert Godwin Sr. remained online for about three hours before it was removed. One video circulating on the Internet has been viewed more than 1.6 million times. Family members of the deceased man, who was a father of nine and grandfather of 14, urged the public to stop sharing the video.

"That is my grandfather show some respect #Cleveland," tweeted Ryan A. Godwin. The message was retweeted thousands of times.

Video shows the suspect getting out of his car and engaging in a brief conversation with his random victim, who is walking in the Glenville area of Cleveland at about 2pm. The victim is then shot for no apparent reason. Stephens also posted a video of him laughing about the murder and claiming he had killed more than a dozen others, police said. "I'm at the point where I snapped," Stephens said on a video posted to his Facebook page.

The suspect claimed he was angry about a relationship with his girlfriend, who is now in protective custody. Police believe he may have fled Ohio. After a search in the area, they found no other victims.

The videos captured the attention of media outlets across the globe. Cleveland Police Chief Calvin Williams said, "If Steve has an issue, then he needs to talk to some folks to get that resolved."

The authorities said the suspect is believed to be armed and dangerous and may have turned off his mobile phone to make him harder to track. The police said to not approach the man. Instead, call police immediately. He might be driving a late-model white Ford Fusion with an Ohio temporary tag of E36360.

The victim's son, Robert Godwin Jr., said his father was a retired foundry worker and was a "good guy."

The suspect is described as a black male, 6-feet, 1-inch tall. He is bald and weighs about 244 pounds. He was last seen with a full beard and wearing a dark blue and gray striped shirt, police said.
