Sixteen year old Alex Hribal was the typical good kid who lived a fairly good and normal life in Murrysville county, a suburb of Pittsburgh.

His lawyer Patrick Thomassey says his client was not a loner, had no history of mental illness, a B student and well-liked in his school.

But something snapped and made freckled-face Alex Hribal go berserk early Wednesday morning.

Wielding two kitchen knives, he slashed and stabbed 21 individuals - teachers and schoolmates - at his own Franklin Regional High School.

It took five minutes before Hribal was subdued by an assistant principal a few minutes after seven in the morning.

The Pittsburgh District Attorney's office charged Hribal with 21 counts of aggravated assault and four counts of attempted homicide and will be held without bail.

A brief indictment hearing was held Wednesday where District Attorney John Peck told media that Hribal was making comments of wanting to die.

The defense lawyer sought a psychiatric evaluation for his client and appealed that Hribal be tried as a juvenile. If tried as an adult and convicted, Hribal will spend the rest of his adult years in prison.

Thomassey said before a barrage of media interviews that his client regrets what he did but is unaware of the gravity of his actions. He described the boy as "confused, scared and depressed." He adds that the next few days will allow Hribal to become somber and fully understand his deed.

Observers initially believed that Hribal snapped as a result of bullying but Thomas Seefeld, the chief of Murrysville police, claimed that he was unaware of any bullying incidents involving Hribal.

Of the 21 injured by Hribal, five were initially pronounced as critical but were later declared safe.

Some of the survivors were surprised at what Hribal did while those critically injured feared for their lives after realizing they were stabbed at the back.

School superintendent Gennaro Piraino says Franklin Regional High School might open again this Monday as soon as the school is cleaned up and restored to pre-incident conditions.
