NASHVILLE, Tenn. — Former NFL quarterback Steve McNair and a woman were found shot to death Saturday afternoon inside a condominium in downtown Nashville, police said.

Police spokesman Don Aaron said authorities were still investigating the shootings and that no suspects were in custody.

"I don't have any answers for you now as to what's happened, who's responsible," Aaron said.

Aaron said the 36-year-old McNair died of a gunshot wound to the head. He said police tentatively identified the woman, but did not release her name.

"There are persons who were around the complex today, visitors, who have been taken to headquarters for questioning, just to see what they know, what they may have seen," he said.

Aaron said officers went to the scene after receiving a call about injured persons inside the condo.

"When police officers arrived in response to that call, they found two individuals who had been shot to death inside the residence," he said.

The condominium is one that McNair was known to frequent, but police spokeswoman Kristin Mumford said she didn't know if he was the owner.

McNair played 13 seasons in the NFL and led the Titans within a yard of forcing overtime in the 2000 Super Bowl, which they lost 23-16 to the St. Louis Rams. He also played for the Baltimore Ravens before retiring in April 2008.

"We don't know the details, but it is a terrible tragedy and our hearts go out to the families involved," NFL commissioner Roger Goodell said in a statement.

"We are saddened and shocked to hear the news of Steve McNair's passing today," Titans owner Bud Adams said in a statement. "He was one of the finest players to play for our organization and one of the most beloved players by our fans. He played with unquestioned heart and leadership and led us to places that we had never reached, including our only Super Bowl."

About 50 people crowded just beyond police tape outside the complex in the upscale Rutledge Hill neighborhood, some wearing Titans hats. The condominium is located within walking distance of an area filled with restaurants and nightspots, a few blocks from the Cumberland River and within view of the Titans' stadium.

McNair began his career in 1995 with the Houston Oilers, who eventually became the Titans, and finished with 31,304 yards passing and 174 touchdowns. McNair played with pain for several years, and the injuries ultimately forced him to retire.

McNair's most noted drive was the final one of the 2000 Super Bowl. He drove the Titans 87 yards in the final minute, 48 seconds, only to come up a yard short of the tying touchdown. Kevin Dyson caught his 9-yard pass, but was tackled at the 1-yard line by the Rams' Mike Jones.
