Jared Lee Loughner, aged 22, the prime accused of open-fire incident outside strip mall in Tuscon last Saturday made his first public appearance on Monday since the incident.

In tan prison uniform he arrived at 2 p. m. in the Phoenix courtroom of Magistrate Judge Lawarence Anderson and appeared calm and composed and did not hint how he would plead the charges slammed against him.

Mr. Loughner is held guilty of shooting seven people in all including a Congresswoman, Gabriel Giffords who is still fighting for her life in a hospital.

He is said to be having a vague interaction with Giffords way back in 2007 when he attended a similar event to the one on Saturday.

The federal charges slapped against him include two murders, two attempted murders and one count of attempted murder of a Congress member.

It was found that Mr. Loughner had a troubled childhood without any social interactions. His teachers and classmates described him "weird and one with paranoid mind". He even has a criminal background with graffiti writing and drug charges being slammed on him in the past.

The judge asked him simple questions and Loughner though, appeared nervous at first, seemed to understand what was happening .

An introductory hearing is set for January 24. If confirmed for murder charges, he could face a death penalty.
