Gamble left behind a blog filled with disturbing and dark images of death, shootings and references to the 1999 Columbine high school massacre in Colorado. It also has several references to Adolf Hitler and Nazis.
Police say the teen, who was found dead in a home in Timberlea, N.S., is linked to the plot to kill a number of people in Halifax on Valentine's Day. The alleged plot was foiled by police and federal officials in both Canada and the U.S.
Lindsay Kantha Souvannarath, a 23–year–old from Geneva, Ill., and Randall Steven Shepherd, 20, of Halifax have been charged with conspiracy to commit murder.
Police said they seized three long-barrelled rifles from the home where Gamble's body was discovered.
Online, Gamble had a dark presence. On his blog, one image says "Valentine's Day it's going down."
Another reads "What doesn't kill me might make me kill you."
Justice Minister Peter MacKay was asked earlier Saturday if the suspects had Columbine beliefs.
"I cannot confirm that," replied MacKay. "But what I can tell you is that this appeared to be group of murderous misfits … prepared to wreak havoc and mayhem on our community."
Friends mourn teen
Online, comments mourning Gamble were posted on a number of blogs.
One, operated by two girls "brought together by a mutual interest in Columbine" among other things, posted a memorial to Gamble.
"Rest in piece (sic) James, my small mammal, my mouse, I love you," it said.
"He did a bad thing (we all mess up in our lives at least once) but it's not the sole thing that determines whether he was a good person," another comment reads.
