It’s rare to go from winning a Grammy Award to holding a family hostage, but that is exactly the story of one disturbed man.

A Grammy Award-winning recording engineer was shot and killed by SWAT officers after a reported hostage situation at his home, according to Tennessee police.

Mark J. Capps, 54, who was wanted on two counts of aggravated kidnapping and two counts of aggravated assault, was shot sometime after 2 p.m. on Jan. 5 at his Nashville home, Metropolitan Nashville Police Department spokesman Don Aaron said in a recorded statement on the police department’s YouTube page.

At about 3 a.m. on Jan. 5, Capps woke up his 60-year-old wife and 23-year-old stepdaughter at gunpoint, Aaron said. He took them into the living room, “repeatedly pointed his pistol” at them and refused to let them leave, he said. Capps told the women that if they tried to call the police, he’d kill them, Aaron said. He also said he’d kill any officers that responded to the home.

At some point during the incident, Capps fell asleep and the women were able to escape the house, according to Aaron. They drove to a local police precinct, where they told officers what happened.

Arrest warrants were issued for Capps that afternoon, and a SWAT team was assembled due to Capps’ having access to guns and his “violent actions overnight,” Aaron said.

Three SWAT officers went to his home and were setting up outside when Capps opened the door “with pistol in hand,” Aaron said.

One of the officers yelled at him to show his hands, but Capps’ movements “posed an immediate, imminent threat,” Aaron said.

That’s when the officer fired. In body camera footage released by the Metropolitan Nashville Police Department, an officer can be heard shouting “show me your hands” before firing three shots into a glass door, the video shows.

Capps died at the scene, according to police. The Tennessee Bureau of Investigations and the Davidson County District Attorney’s Office are investigating the shooting.

Capps was a recording engineer, mixer and producer who had won four Grammy Awards for “Best Polka Album,” according to the Grammy Awards website.

His most recent win for an album he worked on was during the 51st Grammy Awards in 2009 for “Let the Whole World Sing.” He’d worked with artists such as Neil Diamond, Barry Manilow and Olivia Newton-John, Billboard reported.
