Emerging Details: DJ Megatron Approached By Three Men Before Shooting, Possible Reasons For Shooting Revealed

As details are still emerging in the mysterious murder of former BET DJ and Hot 97 personality DJ Megatron, it's being reported that three men approached him before the shooting.  And he may have possibly been involved in a marijuana buy at the time of shooting.  Deets inside...
Former BET host and Hot 97 personality DJ Megatron, who was murdered in Staten Island over the weekend, was on the phone with a friend when gunned down.
Police sources revealed that the shooting occured while DJ Megatron aka Corey McGriff was on the phone with a friend around 2 a.m. on Sunday.  The friend said all of a sudden, the call dropped. 
Sources tell police that three men accosted Corey and were seen fleeing from the scene.  Cops added that a robbery was unlikely because Corey only had $1 in his wallet and his phone was not taken.
Authories are now saying the shooting could have been a result of an unpaid debt.  The New York Post reported that:

"a user named “Megapayup” left veiled threats on Megatron’s YouTube page regarding the alleged debt: 'Who hides and tries to dodge people they owe. . . . So u say ur not gonna pay the bill. . . Bad shyt will stay happening to u, cuz you do bad.' "

Corey leaves behind an 11-year-old daughter Zaharia, a 4-year-old son Zion and a 9-month-old son Isaiah.
Although Corey's cousin, Lisa Davis Alexandra, said Corey's 4-year-old son told her he saw three men approach his father at a bodega, cops have shot down a theory that they boy might have seen the shooting saying he was at home alseep during that time.
His mother, Louvenia McGriff said, 

"They're trying to cope with the situation, especially the 11-year-old.  She's very hurt and upset and doesn't understand why anyone would want to do that to her dad."

Meanwhile, police say Megatron was on his way to buy a cogar and a small amount of marijuana at the time of the shooting.  Allhiphop.com reports:

According to police, DJ Megatron was talking to a friend on a cellphone, as he allegedly drove to buy a cigar and a small amount of marijuana.
Law enforcement is investigating DJ Megatron's homicide as a possible random crime, a planned hit, or a drug deal gone wrong.

Friends remember Corey as a positive person.  "106 & Park" producer Stephanie Hodges told BET.com,

“Mega was the kind of person you would never catch in a bad mood.  His spirit was infectious. For a show like 106, where the energy of our audience is crucial, he was a very important part of our team. We will miss him as our co-worker and as our friend.”

He leaves behind 3 children.  Such a sad situation.
