Relationship with Steve Stephens
According to Steve in his pre-shooting manifesto, he had dated Joy Lane for three years. Joy confirmed that they had been in a long-term relationship and that he had been a nice guy who was good to her children in a text to CBS News. He thought that she was the love of his life and that they would get married, however, they later broke up. In the video he also blamed his gambling addiction on Joy Lane, saying that she drove him to gamble and lose everything he owned. However, in the video, he also blamed his mother Maggie Green for the lack of concern she showed him. 
On April 16, 2017 (Easter Sunday), at about 11:00 a.m., Steve Stephens uploaded a video on Facebook from his car. He starts off by saying, "Found somebody I want to kill. I'm gonna kill this guy right here. He's an old dude, too." 
Steve Stephens approaches Godwin and says, "Can you do me a favor? Can you say 'Joy Lane?'" Puzzled at his request, Godwin repeats the name in question. Steve Stephens tells him that what is about to happen to him is because of her. Within seconds, Stevie Steve pulls a gun out and shoots Godwin in the head at point blank. He shows the dead body on the sidewalk. He then returned to his car and drove away. 
About an hour later, around 3:00 p.m., Steve Stephens filmed another Facebook Live event. He talks on the phone to someone saying that he snapped and "messed up."  claiming to have killed 12 people. It has not been verified whether he killed other people on Easter Sunday.  Steve's Facebook has been deactivated.
It was later revealed that he posted a Facebook Live video before he murdered Robert Godwin Sr.  In what is being called his video manifesto, he mentions that Joy Lane was his girlfriend and they were supposed to get married. After being with her for three years, he reached a breaking point and he abruptly left her on April 14th.  He also mentioned his mother, Maggie Green, and said that she created the monster he is. 
In another Facebook post, he said the number of people he killed increased to 15. The user called it his "Easter day slaughter." 
Joy Lane's Response to the Murders
“We had been in a relationship for several years. I am sorry that all of this has happened. My heart & prayers goes out to the family members of the victim(s). Steve really is a nice guy... he is generous with everyone he knows. He was kind and loving to me and my children. This is a very difficult time for me and my family Please respect our privacy at this time.” 
Joy posted the following message about the shooting on Facebook before deleting her account:
“This is the fastest way to update everybody. I am safe and with the police. I am Not okay… this is a lot. I can’t believe this is happening. I am very sad for everyone involved. I am praying for them and I am praying for Steve. He needs help.” She has since deleted her account. 
On the night of Robert Godwin's murder, the search has turned into a multistate manhunt. The FBI is offering a $50,000 reward for information leading to Steve Stephens' arrest.  Police got in touch with him once but refused to turn himself in.
Police received an aggravated murder warrant for the capture of Steven. He was eventually found in Erie, Pennsylvania after police received a tip from a McDonald's employee that someone who matched his description was at their drive-thru. He ordered Chicken McNuggets and French fries, but the server stalled on giving him the fries so that police could arrive, which ultimately thwarted him - even though he drove off without waiting for the fries.
He was found by cops moments after and Stephens eventually shot himself dead after the pursuit.
