A man accused of firing a gun during an attack on an off-duty police officer pleaded guilty on Tuesday to aggravated assault, making him the third person involved in the incident to enter a plea in Douglas County District Court.

Addison Jon Leo Giullian, 19, of Lawrence, was originally charged with one count each of aggravated battery and aggravated assault with a deadly weapon, both felonies, according to charging documents. He pleaded guilty on Tuesday to aggravated assault with a deadly weapon. The aggravated battery charge was dismissed as a part of a plea agreement with the state.

Judge Stacey Donovan said that Giullian would be required to register as a violent offender because the crime involved a deadly weapon. She scheduled Giullian’s sentencing for May 26. He has been free on a $50,000 cash or surety bond.

Addison Jon Leo Giullian at his plea hearing on March 28, 2023, in Douglas County District Court. Giullian pleaded guilty to aggravated assault with a firearm in connection with an attack on an off-duty Lawrence police officer.

Giullian was one of five people who were alleged to have taken part in the attack on the off-duty police officer, Austin Corbitt, just before 2 a.m. on Nov. 4, 2022, near the intersection of Bob Billings Parkway and George Williams Way, as the Journal-World previously reported. The others are Zachary Taylor Maddux, 18, of Lawrence; Xaviar Dean Anderson, 19, of Pomona; Jackson Eugene Brouhard, 20, of Lawrence; and a person who was a minor at the time.

During a preliminary hearing in Anderson’s case on Feb. 1, Corbitt testified that he was out for a walk when some men in a car began harassing him. He said he was almost home when one of the men, later identified as Maddux, appeared on the sidewalk and tried unsuccessfully to attack him with a tire iron. Corbitt said he and the man fought in the street, and that the minor then came up and demanded money from Corbitt. The first man then managed to hit Corbitt in the head with the tire iron, and Corbitt said he ran away, bleeding from his head.

As Corbitt ran, he said the men were chasing him in their vehicle. He said he hid under an overpass and called 911, and that he noticed gunshot sounds in the distance and heard the men talking as they drove past his hiding place.

Detective Josh Leitner testified that Anderson helped investigators identify the other participants after his arrest. Leitner said Anderson told them that Giullian fired the gun while the men were chasing Corbitt.

Two of the defendants, Brouhard and the person who was a minor at the time, have both resolved their cases with pleas, according to court records. Brouhard pleaded guilty to one felony count of aggravated battery on Feb. 2 and is scheduled to be sentenced on April 3. He is free on a $50,000 own-recognizance bond, meaning he was not required to put up any money to be released from jail. The person who was a minor was originally charged with attempted murder but pleaded no contest to one felony count of aggravated battery on March 2. He is scheduled to be sentenced on April 13 and is not currently in custody.

Maddux is charged with attempted murder and is scheduled for a preliminary hearing on May 15; he is currently being held on a $250,000 cash or surety bond. And Anderson has been ordered to stand trial on several felony charges — aggravated battery with a deadly weapon, conspiracy to commit aggravated battery, and aggravated intimidation of a witness. A trial does not appear to have been scheduled yet, but Anderson is slated to appear in court on April 4 for a status conference. He is currently free on a $75,000 cash or surety bond.
