Jean-Pierre told a news conference: "We are waiting for the facts to be determined, but in the meantime, what we do know is that there is absolutely no place for hatred or violence in the United States."

The suspect in the shooting of Palestinian students pleaded not guilty Monday to three counts related to attempted second-degree murder, but the judge ordered him detained without bail.

The suspect, Jason Eaton, 48, appeared before the Chettenden County Criminal Court in Burlington via video feed from the county jail, where authorities have held him since his arrest on Sunday.

Police say Eaton used a gun to shoot at the three students on the street near the University of Vermont in Burlington on Saturday evening before fleeing.

Authorities opened an investigation into the attack as a suspected hate crime, and police said two of the victims were wearing Palestinian keffiyeh at the time of the attack.

According to police, two of the students are U.S. citizens and the third is legal resident in the United States, all 20 years old.

Burlington Police Chief John Murad said in a statement: "At this fraught time, no one can look at the incident without suspecting it was a hate-motivated crime."

Police revealed that the three remained under medical care on Sunday, and that two of them had gunshot wounds to the torso, while the third was shot in the lower half of the body.

Two are in stable condition, while the third suffers more serious injuries, she said.
