A tangled web of allegations is emerging from the ongoing investigation of the Nov. 20 quadruple homicide at a marijuana farm west of Hennessey that is garnering international attention.

Yifei Lin, 44, the sole surviving victim of the mass shooting, is now in custody himself at the Kingfisher County Criminal Justice Center.

After treatment of his injuries, Lin was transfered to the county jail Wednesday on an arrest warrant requested by the Oklahoma Bureau of Narcotics.

He was charged Friday in Kingfisher County District Court with conspiracy against the state and aggravated manufacture of a controlled dangerous substance or possession of material with intent to manufacuture.

According to the affidavit filed by the OBN, Lin signed documents claiming to be the 25% owner of the Liu & Chen Inc. marijuana grow facility where the shooting occurred.

The OBN also filed a separate civil action to seize ownership of the 10-acre tract where the grow facility was located at 2730 N 2760 Road, Hennessey.

The seven-page notice of seizure and intended forfeiture filed Thursday in Kingfisher County District Court names Lin as the claimant and record owner of the property.

The notice also alleges Lin is listed as the 25% owner, Richard Ignacio the 75% owner and Kevin Pham the registered agent of Liu & Chen Inc., the entity which was licensed through the Oklahoma Medical Marijuana Authority to operate the grow facility.

Pham, 44, was arrested two days after the mass shooting after agents served a search warrant at his Oklahoma City business office.

In addition to drugs and firearms, agents allegedly found “records of communications alleged to be accociated with Pham [which] revealed evidence... consistent with the unlawful diversion of marijuana.”

According to the OBN’s notice of forfeiture, Ignacio was interviewed by law enforcement the day after the shooting and allegedly said he became affiliated with Pham “for the purposes of obtaining multiple marijuana business registrations in order to satisfy the Oklahoma state residency requirement.”

State law requires that at least 75% of a medical marijuana business be owned by an Oklahoma resident.

Ignacio allegedly told law enforcement he had no investment or involvement in any marijuana business other than allowing his name to be used on licensing paperwork in exchange for money paid to him, according to the filing.

In a recorded OBN interview, Ignacio told agents he made $100,000 over the last two years from marijuana farms where his name was used to fraudulently obtain medical marijuana licenses.

Ignacio told agents he is paid approximately $2,000 per month for each OMMA license, according to the OBN affidavit.

Ignacio also provided agents with his cell phone, which contained a text thread where Ignacio asks Pham whether Lin ever made it in to pay because he owed for November and December.

Prior to the local murders, Lin was charged in another alleged drug-related shooting incident that happened in Oklahoma County in 2020.

In the Oklahoma City case, Lin is scheduled for preliminary hearing next month on charges of assault and battery with a deadly weapon, marijuana trafficking, acquiring proceeds from drug activity and possession of ketamine with intent to distribute.

He Qiang Chen, 56, one of the four local murder victims at the Liu & Chen Inc. marijuana grow site, also had been charged in the Oklahoma City shooting incident, according to online court records.

According to Oklahoma County District Court documents, Chen allegedly ordered Lin to shoot another man on Dec. 8, 2020, over a financial dispute.

The victim of that shooting Jintao Liu, allegedly told police that he and Chen agreed to become partners in a marijuana grow in Oklahoma.

He said He Qiang Chen, Lin and two other men confronted him in a Oklahoma City parking lot where Lin allegedly shot him in the leg.

The OBN notice of seizure states that law enforcement searched an Edmond residence in connection with the Oklahoma City investigation on Jan. 20, 2021, and found documents related to Lin’s purchase of the Kingfisher County property, 27 bundles of processed marijuana, a quantity of Ketamina and more than $95,000 in cash.

Law enforcement arrested Lin on the Oklahoma City charge that same day at the Liu & Chen facility, Kingfisher County Sheriff Dennis Banther told the Times & Free Press.

“It was Inauguration Day and also the day we were moving into our new facility,” Banther said. “We had to break away (from moving) to assist with the arrest.”

Both Lin and Chen were free on bonds of $250,000 each while awaiting prosecution on the Oklahoma City felony charges when a man allegedly identified as Wu Chen, 45, entered the garage on the Kingfisher County property where they were located, along with other workers.

Wu Chen allegedly shot and killed He Qiang Chen and three other Chinese nationals and injured Lin, who fled the building and was found critically wounded in the bed of a pickup truck outside when law enforcement arrived.

In a search of the facility the next day, the OBN seized 1,971 pounds of processed marijuana in pre-packaged one-pound bags and 4,675 marijauna plants in various stages of growth.

The notice of seizure alleges that the Kingfisher County facility was used or intended to be used for “the illegal cultivation, manufacturing, trafficking and distribution of marijuana from December 2020 through February 2022.”

Banther said Lin and Wu Chen, who was denied bond in a hearing last week, are being housed in isolation from each other as well as from the rest of the jail population.

“Mr. Lin is still recovering from surgery and will cost this county for further medical bills as we continue his post-operative treatment to prevent infection,” Banther said, noting his appreciation to voters for approving the funding to construct the new facility where such issues can safely be handled.
