"The gun recovered at the scene of the deaths of Steve McNair and Sahel Kazemi was purchased by Kazemi recently," The Tennessean reports, saying it has confirmed that news with Nashville police.

McNair, 36, a former star quarterback with the NFL's Tennessee Titans, and 20-year-old Kazemi were found dead Saturday. He had been shot four times. She had a single gunshot wound to the head and the gun was found under her body.

As the Tennessean adds:

Police said the possibility of a murder-suicide is still on the table, but there are several other theories of the crime still possible.

Kazemi's ex-boyfriend, Keith Norfleet, was questioned for several hours by police yesterday. (Police spokesman Don) Aaron said he is not a suspect, and there are still no suspects being actively pursued.
