Three Chinese nationals arrested on Interstate 40 in two separate vehicles Oct.
17 pleaded innocent Thursday of felony drug charges.
One suspect pleaded innocent to attempted murder.
Gang Nun Lin, 30, Xiaoya Steven Sun, 22, and Zhao Yang, 22, were arraigned in Mohave County Superior Court.
Sun pleaded not guilty to felony charges of attempted murder, aggravated assault of a peace officer, misconduct involving a weapon, transportation of marijuana for sale and conspiracy to transport marijuana for sale.
Lin pleaded not guilty on felony charges of transportation of marijuana for sale and conspiracy to transport marijuana for sale.
He is in jail on a $250,000 bond.
Yang pleaded not guilty on felony charges of conspiracy to transport marijuana for sale.
He is in jail on a $270,000 bond.
Deputy Mohave County Attorney Craig Friesner called two Arizona Department of Public Safety officers to testify during a bond hearing to continue holding Sun without bond.
DPS Officer Jeff Schoch testified he stopped Lin and Sun driving in a rental car about four miles west of Kingman.
He said he stopped them only to warn them that they had been driving too close to several other vehicles.
Schoch recounted that while he frisked Lin and Sun, he felt a handgun under Sun's jacket.
Sun stepped away, pulled the gun out of his jacket and pointed it at Schoch, the officer testified.
He said he then pulled his gun and shot Sun in a thigh.
Sun was treated for his leg wound at a Phoenix hospital and then returned to Mohave County Jail.
Sun's attorney, Scott Furstman of Los Angeles, argued that Sun attempted to produce the weapon to surrender it to the officer.
Furstman also said that because Sun's fingerprints were not on any of the bags of marijuana found in the car, Sun should not be linked to the drugs.
Friesner argued that Sun had been release on bond in Orem Utah, Sun had pleaded guilty to a felony burglary charge in Utah.
Superior Court Richard Weiss ruled that Sun could be held without bond, citing the seriousness of pointing a weapon at an officer, his misconduct with the gun, the charge of transporting drugs and the felony bond for the Utah charge.
Yang was driving a similar make of rental car when he was stopped on I-40 near Ashfork.
Yang was held in Prescott before being transferred to Kingman.
DPS officers said they discovered about 100 pounds of marijuana in each car.
Sun and Yang gave their addresses as Utah.
Lin said he was from California.
Lin and Yang used a Chinese interpreter while Sun said he spoke English.
They were legally in the country on student visas.
