NEWINGTON, Conn. -- The arrest affidavit of a teen accused of devising a plot to kill classmates at Newington High School reveals details of the student's alleged plans.

Police said that they first learned of 16-year-old Frank Fechteler's alleged violent plan from videos posted on the Internet. They were alerted of the videos, posted on YouTube.com, a video-sharing Web site, by a Canton student who found the videos alarming.

The student told a parent, who contacted police, officers said.

According to the affidavit, three of the videos show Fechteler firing guns at a range, and the other two show bombs being detonated.

Police said that after being alerted of the videos, they interviewed Fechteler, who police said told officers that he had a plan to "shoot and kill certain students at Newington High School that he didn't like."

According to the affidavit, Fechteler also told officers that he planned to bring pipe bombs to the school.'

Fechteler told police he had made more than 40 pipe bombs over the past four years in his basement at home, according to the affidavit. He exploded them in his back yard and nearby woods.

Police said the high school junior told them that "his plan wasn't to kill complete strangers but to kill the people that had been picking on him for a long time."

The affidavit claims that Fechteller told officers that the "killing would end 'the only way a person could end it, by shooting myself in the head.'"

Police said that when they searched Fechteler's home they found a .12-gauge pump shotgun, a 7.62 mm bolt action rifle and a semiautomatic .223-caliber rifle in the teen's closet. Police said the guns are registered to Fechteler's father, William Fechteler.

Police said they also found materials and instructions for making bombs and a list of students targeted in the plan. The affidavit stated that the plan called for "the use of explosives, specifically molotove cocktails, 10 shrapnel pipe bombs, propane bombs and a car bomb."

Police said Fecteler had a target list of about 30 students as well as a list of all of his friends that he would spare.

Channel 3 Eyewitness News Reporter Jamie Roth reported that officers have spoken to all of the students on both lists.

Police said that during their investigation, the student told officers that he had planned to carry out his plot on April 10.

Fechteler pleaded not guilty to two counts of manufacturing bombs.
