According to spokesman Steve LeSueur, at least one of the shooting victims remains in a life-threatening condition.
Authorities have announced that they believe the shooting was not connected to "domestic or international terrorism", while adding that the suspected gunman used an "AR-type weapon."
The shooting occurred on Saturday when state troopers stopped a car with a man, who failed to signal a left turn.
The man opened fire at the troopers and fled the scene, while randomly shooting people. The gunman, reportedly identified as a white man in his 30s, was later killed by officers near a movie theatre.
US President Donald Trump was briefed on the incident, while the FBI and law enforcement agencies have been investigating the case.
Commenting on the shooting, Trump said that he was dealing with Republicans and Democrats on gun control efforts and added that background checks wouldn't have stopped recent gun violence.
"They would not have stopped any of it," Trump stated.
Trump was referring to another recent shooting when a gunman killed 22 people in the Texas border city of El Paso.
