Couple arrested after admitting to murder on Facebook live

A Dallas couple who allegedly admitted to killing someone on Facebook have been arrested on suspicion of killing a teenager in broad daylight.
Hakeem Leprince Griffin-White, 17, and Ashley Ann Coleman, 27, were arrested in Dallas on Sunday for the murder of Drekeiston Alex, 19, who was shot dead on Thursday afternoon in the middle of a street.
Both allegedly admitted in a Facebook video to killing someone, and last week Coleman posted an Instagram picture in which she referred to them as 'Bonnie and Clyde.'
Alex was walking on the 4800 block of Sunnyvale Street at around 2.40pm on Thursday when a man approached him and the pair began to argue, Dallas News reported.
The unidentified man then pulled out a handgun and shot Alex in the chest. The teen died in Dallas's Baylor University Medical Center.
Police released security camera footage of the events leading up to the shooting.
The gunman was driven from the scene by an accomplice in a red Chrysler PT Cruiser, police said.
That car was owned by Coleman, witnesses told police. A second witness also reportedly told cops that Griffin-White shot 'that boy' dead.
Coleman posted a photograph of herself and Griffin-White on her Instagram account carrying an assault rifle and a pistol, captioned 'KASH N KEEM. IM HIS BONNIE HE MY CLYDE.'
They also posted a Facebook Live video in which they held a gun and referred to killing someone, an affidavit said, although the video has since been deleted.
Coleman - who raps under the name Mamme Kash - posted on Friday, 'Im Far From A Murderer. I Swear To God Its All An Image.'
A music video for her track 'Shots Fired (Asian Doll Diss)' shows her waving around a pistol and pointing it at the head of a young woman.
She also posted 'Free me.'
Griffin-White also proclaimed his innocence online, writing 'wtf [the Facebook Live video] gotta do with that boy thoo me n my gurr dnt even know dat n***a.'
'Why Would I Kill Somebody While My Gurr Son Inna Car Df #Think,' he also wrote.
Coleman has been arrested numerous times in Dallas County, and in 2010 pleaded guilty to assault.
Both Coleman and Griffin-White have been charged with first-degree murder. They have been jailed on $500,000 bond each.
