More than two months passed before two men were arrested in the killing of a black man running down a residential street just outside of Brunswick. The arrests came two days after a video of the shooting surfaced online and state investigators took over the case.

Now the father and son, Gregory and Travis McMichael, are charged with aggravated assault and felony murder in the Feb. 23 shooting death of 25-year-old Ahmaud Arbery.

Here are some key developments as the case unfolded based on documents and interviews:

— Feb. 23: Ahmaud Arbery is shot shortly after 1 p.m. and is declared dead at the scene. No arrests are made.

— Feb. 24: Detectives meet with George Barnhill, a district attorney from a neighboring judicial circuit, because the local district attorney planned to recuse herself because Gregory McMichael previously worked for her. Barnhill tells police he believes the shooting was justifiable and tells them to continue investigating.

— Feb. 27: State Attorney General Chris Carr appoints Barnhill to handle the case after local District Attorney Jackie Johnson recused herself. Carr has said he was unaware that Barnhill had already talked to police and offered an opinion on the case.

— April 1: Glynn County police receive the autopsy results and send them to Barnhill.

— April 3: Barnhill writes a letter to police saying he plans to recuse himself because his son used to work with Gregory McMichael but also reiterates that he believes there is not sufficient probable cause to arrest the McMichaels.
