Kingfisher County Sheriff Dennis Banther said Tuesday that the 45-yearold Chinese man suspected in the Nov. 20 quadruple homicide at a Hennessey area grow facility will be returned soon to face charges in Kingfisher County District Court.

Wu Chen was arrested last week in Miami Beach, Fla. on a county warrant, after his license plate was flagged by an electronic car tag reader. He signed an extradition waiver on Wednesday, which will allow county deputies to pick him up and transport him back to Oklahoma, Sheriff Dennis Banther said.

Meanwhile, Oklahoma State Bureau of Investigation crime scene technicians are headed to Florida to process the vehicle Chen was driving for possible evidence, Banther said.

Kingfisher County Commissioner Ray Shimanek, Dist. 2, told the Times & Free Press that county assistance was requested by the Oklahoma Bureau of Narcotics to remove “an ungodly amount” of marijuana from the 10-acre grow site on Nov. 21.

The company operating the facility was identified as Liu and Chen Inc., which was listed in the Oklahoma Medical Marijuana Authority online database as having an expired license as of Nov. 1.

Shimanek said he helped remove about 6,600 marijuana plants, plus about 607 pounds of processed marijuana packaged for sale and “a bunch of loose stuff.”

The marijuana amounted to two 16foot trailer loads and three pickup truck loads, Shimanek said.

Under the supervision of OBN, county equipment was used to transport, destroy and dispose of all the drugs seized, he said.

“We were out there from about 4-11 p.m.,” Shimanek said. “It was a long night.”

Chen is suspected of slaying four other Chinese nationals and critically injuring a fifth in what OSBI is describing as an execution at a medical marijuana grow facility near Lacey.

An OSBI spokesperson said Tuesday that identities of the victims are still being withheld pending next-of-kin notification, which has been made more difficult due to language barriers and their Chinese citizenship.

According to information released by the OSBI, Chen is alleged to have entered a building at the grow site about 5:35 p.m. Sunday Nov. 20.

Chen and several employees allegedly were inside the building, which Banther described as a detached garage adjacent to to a red brick residence, for several hours before the shooting began.

According to information provided by Banther, the sheriff’s office received a call about 7:24 p.m. Sunday reporting a potential hostage situation at the scene.

Once deputies arrived and attempted to secure the location on N 2760 Road west of Hennessey, they found the wounded victim in the bed of a pickup truck parked outside the garage.

Deputies discovered the other four victims, all dead from apparent gunshot wounds, in their subsequent search of the property.

The seriously wounded man was air-flighted to an Oklahoma City hospital.

Chen’s relationship to the company or to any of the five shooting victims is still under investigation.

A motive for the shooting also has not been disclosed.

The marijuana grow facility is one of 72 in the county listed in the OMMA database and one of 7,585 growers in the state, according to the OMMA online database. Five growers are listed in the Hennessey area.

A total of 10 of the county’s grow facilities show expired licenses, according to the database. How many of those are still operating is unknown.

Banther said last week that OBN is the agency currently assigned responsibility for policing alleged OMMA license violations.

Kingfisher County also is home to 12 medical marijuana processors and seven dispensaries, according to the database.
