Grammy award-winning recording engineer Mark Capps was fatally shot by a Nashville police Thursday after holding his wife and stepdaughter said he held them hostage at gunpoint.

The Metro Nashville Police Department's Don Aaron said in a news briefing that a responding SWAT team shot Capps, 54, when he opened the front door holding a gun.

His wife and stepdaughter said he awakened them at about 3 a.m. Thursday and threatened to shoot them before they escaped after he fell asleep. The wife and stepdaughter reported the incident at a nearby police station, which dispatched the SWAT team.

Capp's website says he has collaborated with The Chicks, Neil Diamond, Olivia Newton-John, Amy Grant, Barry Manilow and other artists. He was awarded a Grammy for best polka album in 2006 through 2009 for his collaboration with Jimmy Sturr & His Orchestra.

The Tennessee Bureau of Investigation (TBI) said it's investigating.
