The teenage outcast, who killed eight people, as well as himself, may have had help in his planning.
The high school shooting in Finland was a first. Pekka-Eric Auvinen, 18, may have had internet contacts with Dillon Cossey, 14, according to police. Cossey was arrested in October for allegedly preparing a possible attack at Plymouth Whitemarsh High School in Pennsylvania.
A detective in the case told The Associated Press that he considers it quite possible that the two boys were in communication. He declined to provide details saying the investigation was on going.
Auvinen opened fire at a school in Tuusula, Finland on Wednesday, killing 6 students, a nurse, and the principal. He then shot himself in the head, and died hours later at a hospital.
Detective Rabbe von Hertzen said Finnish police had not yet been in contact with their U.S colleagues about a possible link between the two teens.
In Pennsylvania, Montgomery County District Attorney Bruce Castor said he told his detectives to run the name of the Finnish shooter through the computer seized from Cossey. Cossey did admit in juvenile court to planning an attack at a suburban Philadelphia high school.
Castor said, “None of us really think that there’s going to be a lot here, but we’re going to check it out.” He heard of the possible connection through media reports.
The Pennsylvania authorities were tipped off by a boy Cossey tried to recruit and searched his home last month. They found a rifle, about 30 air powered guns modeled to look like higher powered weapons, swords, knives, a bomb making book, videos of the 1999 Columbine attack and violence filled notebooks.
Finnish investigators said Auvinen left a suicide note for his family and foreshadowed the attack in YouTube postings.
Detective Von Hertzen said Auvinen is believed to have written the suicide note on November 5, suggesting he had planned the attacks for at least two days. He was described as a bullied teenage outcast consumed with anger against society.
