Witnesses of the East Liberty Target stabbing gathered Thursday as the suspect was scheduled to go before a judge.
Leon Walls is accused of attacking several people, including a girl, 16, with a steak knife inside the store last Monday.
He was supposed to go before a judge but did not pass a behavioral test. The hearing was postponed.
"He was a maniac. He should have been caught a long time ago. I heard they were looking for him in a few other states," Rodney Johnson, a witness of the attack, told Channel 11 reporter Vince Sims.
"They got into Target, and when he got in there, he rampaged. He chased my friend around. Then he grabbed a girl and stabbed her. That's when we jumped on him, held him down until the cops came and then they tased him," Johnson said.
Hosea Davis, another witness, chased Walls with a bat and helped restrain him, authorities said.
"Every day since it happened, it’s crazy thinking about it. I would just like him prosecuted as soon as possible," Tyrique Walker said.
No date has been set for the next court appearance.
