Four victims have been released from the hospital as the manhunt for suspected Kentucky highway gunman Joseph Couch stretches into its sixth day.
"For everyone to make it, we're really grateful for it," Gov. Andy Beshear said Thursday, according to WLKY-TV.
A fifth victim remains hospitalized, but is expected to survive.
Couch, 32, has evaded capture since Saturday, after he allegedly used an AR-15 to shoot at unsuspecting drivers on Interstate 75, near London, Kentucky, according to the FBI.
Twelve vehicles were shot at, resulting in the non-fatal injuries of five shooting victims, said authorities. Three more victims were injured as a result of car accidents.
Couch said he planned to "kill a lot of people" and then himself afterward, according to the arrest affidavit, USA TODAY reported.
Authorities said Couch purchased 1,000 rounds of ammo and the semi-automatic rifle used in the shooting the same day he allegedly carried out the attack, WHAS-TV reported.
Couch has been charged with five counts of attempted murder and five counts of first-degree assault.
He was charged with terroristic threatening against a neighbor earlier this year, but the charges were dismissed.
A motive remains under investigation.
