Great laugh. Infectious smile. Lovable guy.

That's the way Anthony Dion best described his half brother Matthew Mitchell, less than 48 hours after the 17-year-old was fatally shot in the head at a Greencastle apartment Saturday night.

"As much as it is a loss to us, it's a loss to everyone that knew him and everyone that won't get the chance to know him," Dion said.

Mitchell, a junior at Greencastle-Antrim High School, is survived by his mother Kathleen Konchalski and father William Mitchell, both of Greencastle. He also has five siblings including Anthony Dion, Kelly DeRigo, Hannah Mitchell, Trinity Mitchell and Michael Mitchell.

*** How to help ***

A GoFundMe page, (https://www.gofundme.com/matthew-mitchell-memorialfuneral) has been set up on Mitchell's behalf by his family to assist with funeral costs.

"We need as much help as possible because we didn't have a life insurance policy for Matt," Dion said. "Nobody would have ever expected what happened and how it happened."

Dion said that it is the family's intention to find a funeral venue that will accommodate Mitchell's many friends who will want to get closure and celebrate his life.

*** His 'baby brother' ***

The 31-year-old Dion knew his "baby brother" as well as anyone since the two were gym partners.

"Even if he made you mad, he was the type of person that would make you smile the next minute," Dion said.

Mitchell enjoyed playing video games, hunting and fishing, according to Dion.

He added that just two weeks ago, Mitchell started a job at Sunnyway Diner and had plans to pursue computer programming after he graduated high school.

As far as the manner of how the incident took place, Dion said, "We understand that it happened with a gun, we aren't against guns, but people need to control their guns. This could have been prevented."
