A large chapter in a 2022 quadruple homicide in Kingfisher County came to a close Friday morning.

Wu Chen, a Chinese national accused of murdering four people and seriously injuring another at a medical marijuana grow facility near Lacey, pleaded guilty to the counts in Kingfisher County District Court.

The plea agreement was accepted by Kingfisher County Associate District Judge Lance Schneiter during a 24-minute hearing at the county courthouse.

The agreement calls for Chen to serve life without the possibility of parole for each of the four counts of first degree murder and 20 years for the assault and battery with a deadly weapon felony.

The counts will run concurrently, according to the deal, which also states the state will not seek the death penalty.

Chen appeared in the courtroom with his wrists and ankles shackled and in an orange jumpsuit.

He was represented by Mitchell Solomon and also had legal and cultural consultants by his side.

The state was represented at the hearing by Jimmy Harmon and Dale Anderson.

There was also an interpreter for the hearing to translate each step of the proceeding for Chen and back to the court.

“And as to the four counts of murder and the assault and battery charge, what is your plea today, guilty or not guilty?” Schneiter asked.

“Yes, I am guilty,” said Chen, according to the interpreter.

Chen has 10 days from Friday to withdraw his plea, according to Schneiter.

He can also face immigration consequences through the Immigration and Nationality Act, which Chen said he understood through the interpreter.

Chen was arrested Nov. 22, 2022, in Miami Beach, Fla., less than 48 hours after the quadruple homicide shooting took place in northwest Kingfisher County at the Liu & Chen Inc. grow facility.

He was listed at 45 years old and a Hennessey resident at the time of his arrest and was extradited to Kingfi sher County.

Chen was denied bond in a hearing in December 2022 and has remained in the Kingfisher County Criminal Justice Center.

According to court documents, Chen was charged with killing four other Chinese citizens identified as Quirong Lin, Chen He Chun, Chen He Qiang and Fang Hui Lee.

He was also charged with shooting Yi Fei Lin, also a Chinese citizen, who was critically injured.

An Oklahoma State Bureau of Investigation affidavit filed in conjunction with the motion to deny bond alleged a possible money motive for the shooting.

The affidavit referred to statements with two witnesses, both identified as workers at the Liu & Chen Inc. facility.

One of the witnesses said he was working in the garage where the shooting happened when a man came in and shot “the boss” in the leg.

The man demanded $300,000 within the next half hour or he was going to kill everyone in the garage, according to the affidavit.

The witness said “the boss,” who is not identified in the affidavit by name, told his girlfriend to call her brother to get the money, according to the affidavit.

The witness said some time later, “the boss” was not doing well and asked the suspect to “finish him off” and the suspect shot him again.

The witness said two other men attempted to rush the suspect and the suspect shot one of them and chased after the other as he ran outside.

When the suspect came back in the garage and pointed the gun at the female, the witness ran out and heard more gunshots, according to the affidavit.

Another witness identifi ed as the brother of the woman who was shot told agents he received a phone call from his sister “stating someone was at the farm to rob them and they had guns.”

The witness didn’t see anyone when he arrived at the front of the property, so he set up his phone to record the garage door and then went and hid, according to the affidavit.

The witness heard a lot of gunshots and then saw the suspect, whom he identified as Chen, who he said worked on the farm about a year previously, according to the affidavit.

The witness said Chen also saw him and started shooting at him as he ran from the property to get help. In the motion to deny bond, the district attorney’s office alleged that when Chen demanded the $300,000, he referred to it as a poriton of his “investment” in the marijuana grow facility.

Kingfisher County Sheriff’s Office deputies were on the scene of the murder late Sunday, Nov. 20, 2022.

Before noon the next day, there was an arrest warrant issued for Chen.

“I’m disappointed there was no death penalty, but at the same time, I’m glad it’s over,” Sheriff Dennis Banther told the Times & Free Press Friday after the proceedings.

Banther called in multiple other agencies to the scene at the time. The Oklahoma Bureau of Narcotics and Dangerous Drugs seized and destroyed all marijuana plants found on the scene when it was determined the facility had been operating without a license since Nov. 1.

The facility has spawned other charges beyond those issued against Chen.

Kevin Pham, an Oklahoma City accountant who was listed as the registered agent for Liu & Chen Inc. on paperwork filed with the Oklahoma Secretary of State, was arrested after an OSBI raid of his Oklahoma City office Nov. 22.

He was charged with multiple felonies last December, including conspiracy against the state, six charges of filing a false/forged instrument, aggravated manufacturing of a controlled dangerous substance, trafficking of a controlled dangerous substance and pattern of criminal offenses, among others.

His preliminary hearing is currently set for 9 a.m. Thursday, April 4, in Kingfi sher County District Court.

Lin, the man seriously injured by Chen, was later charged with conspiracy against the state and aggravated manufacturing of a CDS.

He is set to appear again in court on Feb. 27.
