A 57-year-old man shot and killed his 19-year-old daughter and then himself in their Canton home Saturday evening, according to the Cherokee County Sheriff’s Office.

Police responded to a call around 5:45 p.m. about a person shot in the Bridgemill subdivision. Howard Newhouse fatally shot his daughter, Kathryn, then killed himself, authorities said.

Sheriff’s office spokesman Capt. Jay Baker told Channel 2 Action News that Howard Newhouse’s wife was at home during the shooting. Officials hope she will be able to help investigators piece together what happened.

Parts of the expansive Bridgemill subdivision were blocked for hours during the investigation.

In a public Facebook post, Christopher Newhouse said he is working toward coming to peace with the situation that took his father’s and sister’s lives.

“Although I am incredibly sad that my dad will not get to see me graduate, will never hold his grandkids, or will not be able to attend his son’s wedding, I know that he will be watching from above in a much better seat and I am at peace knowing he loved me and provided me with so many opportunities that I was able to fully take advantage of,” he wrote.

Newhouse added that he had no bad memories of the two and explained that the environment his sister “grew up in prevented her from truly developing the bright and shining personality” he encountered when they were younger.
