A Jefferson County grand jury has added an additional capital murder charge to one of a group of men charged in the robbery and slaying of a man the night after a 2024 mass shooting in Birmingham’s Southside.

Demarco Nakia Beck Jr. was initially charged with capital murder during a robbery in the Sept. 22, 2024, ambush killing of his cousin, 32-year-old Jamarcus McIntyre.

A grand jury on April 4 issued a second warrant for Beck charging him with murder for hire, according to court records made public Tuesday.

The indictment accuses the 29-year-old Beck of shooting McIntyre for hire or pecuniary gain.

AL.com first reported that the suspects waited outside for nearly two hours to gun down McIntyre and steal his backpack.

The ordeal was documented in a flurry of text messages between Beck and other suspects – including accused mass killer Damien McDaniel.

Court documents do not say who hired the suspects to kill McIntyre.

The others charged in McIntyre’s murder are McDaniel, Larry Rollins, 32, Ny’Quan Lollar, 22, Zachary Holmes, 31, and Crishawn Ja’mel McLemore-Bruce, 23.

The shooting happened at Holmes’ house, who was also a cousin to the victim.

McIntyre died in a hail of gunfire that Sunday night in the 700 block of 81st Place South.

The deadly shooting happened less than 24 hours after the Five Points South mass shooting.

Jefferson County prosecutors contend in court documents that McDaniel and Lollar were among three shooters who opened fire on McIntyre.

The horrific ambush was captured on home surveillance video. Investigators have not yet been able to identify the third shooter.

The video showed gunmen killing McIntyre and stealing his backpack.

Authorities say the suspects waited roughly two hours outside the residence until McIntyre was gunned down.

Text messages from the suspect’s phones showed multiple, and simultaneous, conversations were taking place in the hours leading up to McIntyre’s slaying.

Holmes, according to court records, was inside the house with McIntyre feeding information to the other suspects, including Rollins and Beck, who were not at the actual scene.

The shooters remained in the car until McIntyre exited the house and was immediately killed.

Multiple, and simultaneous, conversations were taking place in the hours leading up to McIntyre’s slaying.

Holmes texted Beck the exact address and described McIntyre. “White tee black shirt black book bag black hat only mf with a hat on.”

Rollins then relayed the address to McDaniel, accompanied by two photos of McIntyre.

McDaniel, at one point, told Rollins that a neighbor kept going outside and looking.

“Where bout? Send a pic” Rollins texted McDaniel, who sent Rollins and Beck a photo of the house across the street from where the killing took place.

Shortly before 9 p.m., McDaniel, in a text to Beck and Rollins said, “I’m finna run in det hoe.”

He was told the doors were locked and replied, “I got sum to open em.” He also texted, “I’ll set the bitch on fire bet they kum out den.”

He then texted Beck and Rollins, “I’m jst talk shit doe I’m swatting.‘”

Rollins “hearted” McDaniel’s text and Beck “laughed” at the text.

Records also show multiple phone and Facetime calls – both incoming and outgoing – logged on Rollins’ phone leading up to the 9:18 p.m. shooting.

McIntyre left behind two children, and a large family still grieving his loss.

“When he died, I died,‘’ said his mother, Ada Jones McIntyre. “He was my baby.”
