Jesse Heard, Will McDonald’s sister-in-law: “She's mourning, she’s mourning the loss of her baby.” 

Leaving court, sometimes in tears, the mother of a 10-year-old boy wonders what’s next. Her husband…

Judge: “Will McDonald, charged with manslaughter.”

… her dead son's dad is accused of shooting and killing the boy Thanksgiving night.

According to prosecutors, McDonald heard a car alarm go off, went outside with a gun and shot the boy.

In court today he started to talk.

Will McDonald, manslaughter suspect: “Can I say something?”

Judge: “Just a second.”

But never did.

Jesse Heard: “We’re here in support of Will. He’s not a monster. He made a mistake. We have to support our brother we still have to be there for him.”

Don Kleine, Douglas County Attorney (R): “He has to be held accountable. Obviously, I’m sure he didn't mean to shoot his son but the fact that he fired a gun at somebody who's just walking, or coming up towards him without being threatened in any manner is not OK.”

Jesse Heard: “We're burying a child, a baby. And at the same time we have to love and support our brother. We still have to be there for him. This is crushing him.”

McDonald is being held on $750,000 bond, needs $75,000 to get out. His next court date is January 9. Along with manslaughter, he also faces two gun charges and the possibility of life in prison.
