Jared Lee Loughner made his second appearance in court since the January 8 shooting spree that left six people dead and entered a plea of not guilty on Monday.
The 22-year-old faces charges of the attempted assassination of US Representative Gabrielle Giffords and the attepmpted murder of her two aides; he will be charged for the other killings in state court.
Loughner’s hair has grown out and his sinister “smirk was back on his face,” according to CNN. He entered the courtroom in Phoenix, Arizona 10 minutes before the judge came into the room and was looking around, smiling and chuckling a little bit.
“He seemed like he was enjoying the attention he was getting,” CNN reported.
The six people who died in Loughner’s rampage were U.S. District Judge John Roll, 63; 9/11 baby Christina Taylor Green, 9; Giffords aide Gabe Zimmerman, 30; Dorothy Morris, 76; Dorwin Stoddard, 76; and Phyllis Schneck, 79.
