A second arrest in the case of a man shot to death while trying to protect a neighbor from robbers in Birmingham.  20 year old Aronde Samuels was picked up by police just days after news that the elderly robbery victim had died from a heart attack.  Her family says the stress of the ordeal brought on her death. Samuels and 22 year old Davarius McGee face capital murder charges in the death of 53 year old Arthur Lee Mills who confronted the men as they robbed the woman of her car and jewelry.  He was also armed.  He was killed when the three exchanged gunfire inside the woman's home.
