FORT WAYNE, Ind. - Police say a sniper has killed a man who fatally shot a bus passenger in a northern Indiana city before taking a 3-year-old boy hostage.

Fort Wayne Police Chief Rusty York said Wednesday that Kenneth Knight, 45, was killed by a single shot from a sniper.

Police spokeswoman Raquel Foster told The Journal Gazette shortly before that officers had taken the child from the house where he had been held hostage by the man who  pulled a 49-year-old woman off a city bus and shot her Wednesday morning.

The Allen County Coroner's office identified the woman as Jacqueline Bouvier Hardy of Fort Wayne. Hardy recently filed a protection order against her ex-boyfriend Knight.

"It's just terrible, it doesn't make any sense," said Hardy's brother, D'Angelo Hardy. "That's somebody's mom, that's somebody's sister, that's somebody's friend that they took away from here."

Fort Wayne Police knew who they were looking for, and they used K-9s to track Knight to a house, where he took the 3-year-old son of an acquaintance hostage.

Krista Stockman, a spokeswoman for Fort Wayne Community Schools, said the district is prepared to address the shooting with any children who might have witnessed it.

"We would ask that if any parents hear their child talking about it or maybe think that their child saw something to let us know," Stockman said. "We will do everything we can to help them and their children."
