Both men had been free since the February 23 incident, but when the video leaked this week there was mounting pressure for them to be arrested. The GBI officially took over the case Thursday from local cops in Brunswick, GA.
The haunting video showed Ahmaud jogging down the street when he was stopped and confronted by the McMichaels. A brief struggle between Travis and Ahmaud took place before gunfire ... and Ahmaud fell to the ground.
A 911 call from that day was also released Thursday. In the call, you can hear who appears to be Gregory McMichael talking to a dispatcher, saying, "He's running right now. There he goes right now."
There were allegations of corruption because the elder McMichael used to be an investigator for the Glynn County D.A.'s Office. After the video came out, the D.A. formally asked the GBI to investigate the now 2-and-a-half-month-old case.
