A charge of second-degree murder was laid Tuesday against Dylan Dingwell, in the first homicide investigation on Prince Edward Island since 2006.

Dingwell, 22, is accused in the shooting death of his 25-year-old brother, Kyle Dingwell, on Monday in a quiet residential area of Charlottetown.

Dylan Dingwell appeared in a Charlottetown courtroom and was remanded into custody. He is scheduled to be back in court Jan. 24.

Police said they were called to a home on Ridgemount Court at about 11 a.m. Monday. Kyle Dingwell was taken to the Queen Elizabeth Hospital with a gunshot wound in his upper body. He died shortly before midnight.

Police seized a .38 calibre handgun from the scene and interviewed two men who were in the home when they arrived. Police said Kyle Dingwell lived with his mother in the home.

"It appears as though it was an argument or a disagreement that escalated and had dire consequences," Deputy Chief Gary McGuigan said Tuesday.

Friends set up a Facebook page in memory of Kyle Dingwell, and throughout the day, people shared memories and condolences.

A couple of friends, who did not want to be identified, described Kyle as extremely friendly with a great sense of humour. They told CBC News they're in shock over his death.

They also said it appeared Kyle and Dylan got along just fine.

Police said they, too, were having a hard time understanding the shooting.

"It's tragic," McGuigan said. "It's not just the loss of one son, it's the loss of two sons. And our condolences go out to the family."

He said police were still sorting through evidence gathered Monday.

Shootings and homicides are rare on P.E.I. The province's last murder occurred in May 2006, when Arnold Sanderson ran down Shawn Smith with his car. Sanderson pleaded guilty to second-degree murder in October of that year.

The last shooting was in January 2004. Rae MacFarlane was attacked in his home in Donagh, shot twice and left for dead. MacFarlane survived and there have been no arrests in that case.
