The Chicago man who allegedly shot dead the 9-year-old son of a rival gang member after luring him into an alley was recorded in a jailhouse conversation saying that he laughed immediately after killing the boy execution style.

Dwright Boone-Doty, 25, was heard on tape talking about the November 2015 slaying of Tyshawn Lee.

In describing the shooting, Boone-Doty is overheard saying: ‘I’m looking at him. We walking. Bop. Hit the ground.

‘Bop-bop-bop-bop-bop. I’m laughing. I’m looking ... Bop bop bop bop bop man.’

Prosecutors played the recording during Boone-Doty’s trial earlier this week in Cook County, Illinois, according to the Chicago Sun-Times.

Boone-Doty was arrested and charged along with two other men - Corey Morgan, 31, and Kevin Edwards, 26 - who allegedly helped him kill young Tyshawn.

Edwards, who drove the getaway car, has been sentenced to 25 years in prison after pleading guilty to murder.

Morgan is being tried together with Boone-Doty but with separate juries.

Boone-Doty was recorded in Cook County Jail conversing with Demetrius Murray, a high-ranking gang member who had been sentenced to 10 years for involvement in a separate shooting.

Boone-Doty was at the jail on an unrelated gun charge.

Murray testified in court this week that he agreed to wear a recorder in order to obtain incriminating evidence against Boone-Doty.

He said he offered to help authorities after he heard Boone-Doty’s disturbing account of how he allegedly killed the young boy.

Initially, Murray admitted that his first motivation was to get a lighter sentence on his aggravated battery case.

‘My other motivation was that, like, a person that brags about things like that, it don’t add up to me,’ said Murray.

On the day of his killing, Tyshawn was still wearing his school uniform when he headed to a park to play basketball

Detectives said Tyshawn was targeted in retaliation against his father, suspected gang member 25-year-old Pierre Stokes (pictured in November 2015)

‘It ain’t right.’

According to prosecutors, Boone-Doty lured the little boy into an alley by promising him a juice box and then shot him at close range.

The nine-year-old was hit three times, including once in the head and once in the back.

The third bullet severed the top of the boy's right thumb, suggesting he tried to block the bullets with his hands, his autopsy found.

Prosecutors allege that Boone-Doty, Morgan, and Edwards - reputed members of the Black P. Stone Nation Bang Bang Gang, or BBGs - killed Tyshawn because they believed his father, Pierre Stokes, was a member of the Killa Ward faction of the Black Gangster Disciples gang responsible for a shooting that killed Morgan's brother, 25-year-old Tracy Morgan, and wounded their mother.

In his recorded conversation, Boone-Doty is heard saying that he and his co-defendants were at Dawes Park on the afternoon of November 2, 2015.

In her opening address, prosecutor Megan Hillman said the killing of Tyshawn (pictured with his mother) cane from a 'singularly evil person'

Boone-Doty said that initially the three men who spotted Tyshawn alone in the park planned to kidnap and then torture him.

Morgan and Edwards then left, leaving Boone-Doty alone, he says in the recording.

Boone-Doty is recorded as saying he went over to Tyshawn and started dribbling his basketball as a ploy to lure him to come over to him.

‘I don’t know what they thinking in their head,’ Boone-Doty said.

‘I’m thinking in my head, “I gotta get this b**** off the side. F*** this.”

‘I take the ball.’

Boone-Doty said that he offered to buy Tyshawn whatever he wanted at a local store.

He then walked with Tyshawn toward a nearby alley. He says he looked around for the SUV that he rode in with Edwards and Morgan, but couldn’t see it.

He says that at this point he shoots him in the alley.

In a subsequent conversation with Murray that was also recorded, Boone-Doty describes the gun used to kill Tyshawn - a .40-caliber handgun.

He also graphically describes how a round penetrated the boy’s skull.

‘Dude, because I had the .40. I had like 15 shots and I hit shorty (Tyshawn) like 12 times,’ he said.

Kevin Edwards, the alleged getaway driver, pleaded guilty to first-degree murder in exchange for a 25-year prison sentence

‘He so little. The (bullets) are coming out. I see that b*** go in his head. Boom!

‘That b**** came out, right here, like.’

Murray is heard on the tape asking Boone-Doty is he had any remorse about shooting a nine-year-old boy.

‘So tell me this, though. This is some real s—t. You don’t feel no type of way about killing that kid?’ Murray asked.

‘They killed my brother...that feelings (of guilt) is for s***,’ Boone-Doty said.

‘You got to be in this s*** all the way or not be in this s*** at all.’

Boone-Doty’s lawyer, Assistant Public Defender Danita Ivory, said that her client’s statements were simply a case of exaggerated bragging in order to impress a fellow inmate.

During cross-examination of Murray, Ivory suggested that Boone-Doty was in awe of him both because of his size - 6ft5in and weighing 300 pounds - and his status as a senior gang member.

‘People say a lot of things, don’t they?’ Ivory asked Murray.

‘When certain people do things, they always add on extra stuff to it,’ Murray replied.

Closing arguments are scheduled for Thursday, with jury deliberations expected to begin either Friday or the start of next week.
