CHARDON, Ohio - A prosecutor says the 17-year-old suspect in a fatal Ohio school shooting didn't know his victims and chose them randomly.

Prosecutor David Joyce said at Tuesday's hearing that suspect T.J. Lane admitted firing 10 shots at Chardon High School.

At the hearing, Judge Timothy Grendell imposed a gag order on opposing attorneys at the prosecutor's request and told the media not to photograph the boy's face, as he is a juvenile.

The boy was ordered held for at least the next 15 days. Prosecutors have until March 1 to charge him.
