New York City ? Two teenagers were charged with conspiring to attack a Long Island high school on the anniversary of the Columbine attacks after a chilling journal and videotape surfaced in which one teen identifies several potential victims by name, authorities said Friday.

Authorities said the two suspects, co-workers at a suburban McDonald’s, targeted scores of students in an attack they planned for April 20, 2008 – the ninth anniversary of the Columbine High School rampage, where 12 students and a teacher were killed in Littleton, Colo.

The two teens planned to attack Connetquot High School in Bohemia, about 50 miles east of New York City, Dormer said. The 15-year-old was the driving force behind the plan, authorities said, and was recently suspended for making threats of violence.

The 15-year-old, whose name was withheld due to his age, appeared in juvenile court Friday in handcuffs. The charges were not read, and a plea was not entered. Instead the judge ordered two weeks of medical evaluation at the Sagamore Children’s Hospital, according to a report posted on Newsday’s Web site. The teen’s mother and stepfather were in the courtroom, but would not comment.

The second suspect, 17-year-old Michael McDonough, pleaded not guilty.
