An Albany man is accused of attempted murder for allegedly attacking the man with whom his ex-wife was having a relationship, according to court documents filed in the case.

The Tuesday night assault occurred at the Corvallis Nail Spa, 2321 NW Kings Blvd. Police arrested 48-year-old Than Duy Kim later that evening.

According to an affidavit filed in the case, Kim is accused of using a baseball bat and knives to attack 50-year-old Mitch Xuan Dong. The victim was on life support Thursday at Good Samaritan Regional Medical Center. Kim also allegedly pointed a handgun at Dong, as well as his ex-wife, who is identified as Anh Tram Gia Phan in court documents.

According to a document filed Thursday in Benton County Circuit Court, Kim faces one count of attempted murder, three counts of first-degree assault, four counts of unlawful use of a weapon and one count of pointing a firearm at another for the alleged attack on Dong.

Kim faces additional charges for alleged crimes against Phan, according to the court documents. Kim is charged with pointing a firearm at another, fourth-degree assault and recklessly endangering another person for allegedly assaulting Dong in front of Phan and causing her injury. The extent of Phan's injuries were unknown.

Kim appeared in Circuit Court on Thursday afternoon via video conferencing from the Benton County Jail. Judge Locke Williams appointed Danielle O’Brien and David Corden to represent Kim. O’Brien entered not guilty pleas to all charges on Kim’s behalf.

Williams imposed a $675,000 bond in the case.

During Kim’s arraignment, Chief Deputy District Attorney Ryan Joslin called the alleged attack a “brutal bludgeoning.”

“(Kim) left the victim lying unconscious on the ground in a pool of his blood,” Joslin said.

According to the affidavit, Phan called police to the salon at 8:13 p.m. Inside the business, officers found Dong, who was unconscious and had a significant head injury, the affidavit states. Dong was taken to the hospital, where doctors determined he had a significant skull fracture, and where he underwent brain surgery, according to the affidavit.

According to the affidavit, Dong suffered several injuries that were defensive in nature.

Phan told police she was the owner of the salon, the affidavit states. Phan said she and Dong were at the business after hours having sex when Kim entered the salon, shouted a profanity and then assaulted Dong, the affidavit says.

While examining the area, police found a baseball bat and a bloody knife in a nearby dumpster, the affidavit states.

When contacted by police, Dong’s wife said she had received a phone call from Kim and that he had told her Dong would not be coming home that night because he had just assaulted Dong with a baseball bat, according to the affidavit.

Albany police arrested Kim at 1:14 a.m. Wednesday at his home, the affidavit states. Kim confessed to the assault when interviewed by officers, but initially claimed he was only defending himself, according to the affidavit.

Kim told officers he went to the salon and saw cars belonging to Dong and Phan parked outside, the affidavit states. Kim said he entered the business brandishing a handgun in one hand and a baseball bat in the other, according to the affidavit. He said the gun fell out of his hand but he used the bat to strike Dong multiple times, the affidavit states.

According to the affidavit, Kim told officers Dong fell to the ground and he continued to hit him. Kim also said he picked up a nearby knife and hit Dong with it and that when the knife’s blade broke, he picked up a second knife and used that to slash Dong’s face, the affidavit states.

According to the affidavit, Kim told officers he left the salon and discarded the knife and the bat in a nearby dumpster.

When asked by officers to describe the emotions he felt during the alleged attack, Kim said “closure,” the affidavit states.

Kim’s case is set for a status check hearing on Dec. 12.
