The gun found at the scene of the deaths of Steve McNair and Sahel Kazemi was purchased by the woman, police have confirmed. Kazemi, 20, died of a single gunshot to the head alongside McNair, who had two gunshots to the head and two to the chest. The gun was found under Kazemi's body. "We believe the pistol recovered from the apartment was purchased by Kazemi," Metro police spokesman Don Aaron said. Police said the possibility of a murder-suicide is still on the table, but there are a number of other scenarios on the table as well. Kazemi's ex-boyfriend, Keith Norfleet, was questioned on Sunday by police and is not a suspect. "He was cooperative during questioning, then he went on his way," Aaron said.
