Video captures frantic 911 call

Harrowing doorbell video captured the moments after former NBA player Adreian Payne was gunned down in Florida – as a woman who identifies herself as his mother pleads for help from 911.

“Please help me! Help me! He shot my son dead. Help me! I don’t know the address. He shot him! He just died. Please help me!” the woman is heard yelling, the footage obtained by Fox 35 News shows.

Seconds earlier, a gunshot rings out and two people are seen running along Egret Shores Drive in Orlando on Monday.

Payne, 31, a former Michigan State star who played four seasons in the NBA, including for the Orlando Magic, was allegedly killed by Lawrence Dority outside the suspect’s home, police said.

Dority, 29, pleaded not guilty on Tuesday to first-degree murder with a firearm.

According to legal documents, a witness told police that Payne arrived at Dority’s home to possibly act as a “mediator” between Dority and his girlfriend.

The witness reportedly said Dority and his alleged partner “have a relationship where they argue often.”

Citing a police affidavit, the Detroit Free Press reported that Payne’s girlfriend told investigators that the couple had asked to come to Dority’s residence to assist Dority’s girlfriend, Tatiana Mesa.

Payne’s girlfriend’s name was redacted in the police report.

Dority told police that Payne “had no business being at his residence this late at night,” and that he perceived Payne’s “presence as a threat,” TMZ reported, citing legal documents.

Police said Dority claimed Payne made “movements with his right hand in the right side of his waistband,” before telling Dority, “I’ll smoke you, brah.”

Dority then grabbed a gun from his home and fired one round at Payne, police said. He allegedly told cops he was “protecting his family and protecting his home” and that “his actions were justified.”

“This man tried coming to my house, he cut around my block, and he tried shooting me. … He act like he got a gun, and I shot him,” Dority told 911, according to the affidavit cited by the Free Press.

But authorities determined that Payne, who was not armed, was “not threatening Dority in any way.”
