Antonio Hendrix was killed after an argument outside a Detroit barbershop on June 1, 2013. While on his cell phone he was approached by three men; an argument escalated when one of them knocked the phone from his hand and pushed him down. Antonio ran into the barbershop and barricaded himself in a storage room, but the man who followed him—identified as Daron Lee Harrell—kicked at the door and fired four shots through it. Antonio was hit in the hip and chest, taken to hospital, and died the next day.

The case sat cold for five years until Harrell was arrested for carrying a concealed weapon. Forensic testing linked the Ruger P98 he had to the bullets that killed Antonio, DNA under Antonio’s fingernails matched Harrell, and a witness identified him as the man who followed Antonio into the shop. At trial Harrell denied being present and said he had been at a family birthday party; he acknowledged selling marijuana to Antonio earlier that day and suggested a handshake could explain the DNA. The jury convicted Harrell of second-degree murder, felon in possession of a firearm, and two counts of possession of a firearm during the commission of a felony; he received a 30 to 45 year sentence for the murder conviction, with additional time for the firearm counts.

Did anyone in the area that day notice the three men who approached Antonio or see what happened outside the barbershop?
