While the investigation is still going on about the shooting death of Ahmaud Arbery, there was a note that was left at a makeshift memorial where he died. The note read, "Ahmaud, I am so sorry. I should have stopped them. I am so sorry." No one really knows who left the not, but when a news station saw it, a picture of that note was taken and would be a part of the case. The way the note read, it seemed as if there was a witness. Arbery's family attorney Lee Merritt got wind of that note and of course wanted it to be investigated. But according to TMZ, the GBI (Georgia Bureau of Investigation) said it already identified the author and determined he or she was not connected to the murder investigation. Merritt says GBI has not told his team the identity of the person it already spoke to about the note. But it makes you wonder how did GBI already identify the person responsible for the note. Meanwhile, Merrit told TMZ he and his team of investigators received what they believe is a credible tip claiming the note's author is someone who shares ties to Travis and Gregory McMichaels the two men who are responsible for Arbery's death, and/or William "Roddie" Byran who recorded the shooting, who claims to be innocent. Merritt still wants that note to really be investigated after that tip.
