An 18 year old has been arrested in connection with the murder of Amanda Blackburn, who was shot in the head during an alleged home invasion in Indianapolis. [Snip] Pastor Davey Blackburn found his wife's body when he returned from the gym. He told ABC News' Good Morning America show "Amanda didn't have an enemy in the world. I can't imagine any reason why. That's why this has baffled us as much as anybody," he said.
