A Chinese national who allegedly shot and killed three men and one woman and critically wounded another man at a county medical marijuana grow facility Nov. 20 was booked into the county criminal justice center Thursday night.

Kingfisher County Sheriff’s Offi ce personnel Lt. Ken Thompson and Deputy Jason Wiebelt drove a 3,120-mile roundtrip to Miami Beach, Fla., to transport Wu Chen, 45, back to this jurisdiction.

Chen was captured without incident less than 48 hours after the alleged shooting when his vehicle license plate was flagged by an electronic car tag reader and he was stopped by local police.

He was arrested on a Kingfisher County warrant issued the day after sheriff’s deputies were called to the Liu & Chen Inc. grow facil- ity west of Hennessey and found a critically-wounded man in the bed of a pickup truck and four other people shot dead inside a nearby garage.

Chen signed a waiver of extradition, agreeing to be returned to Oklahoma.

“We dealt with a lot of moving parts to even do the transport,” Banther said.

“Our preference was to use the U.S. Marshal’s JPATS (Justice Prisoner and Alian Transportation System) and fly him to the transfer center in Oklahoma City.

“We weren’t able to do so with their schedule and the remaining issues, so it came down to good old fashioned grunt work – and a lot of driving.”

Oklahoma State Bureau of Investigation agents traveled to Florida ahead of the sheriff’sofficerstointerview Chen in the Miami-Dade County Detention Center and process his vehicle for evidence, Banther said.

Thompson and Wiebelt arrived at the Kingfisher County Criminal Justice Center with Chen shortly after 7 p.m. Thursday, where most of the sheriff’s office staff was present to aid in the booking process.

“They were involved from the beginning and they wanted to see it through,” Banther said. “I’m fortunate to have a staff that is so willing to work even through the darkest challenges.

“It shows professionalism for the job, but more importantly, their character.”

Chen is being held without bond and is expected to make his first court appearance next week.

Formal charges had not yet been filed at press-time Friday.

OSBI is describing the shooting deaths as “an execution.” Witnesses allegedly reported the killings happened after Chen and the victims were shut inside the detached garage for several hours.

The incident was first reported to the sheriff’s office as a possible hostage situation.

No information has been released as to what relationship, if any, Chen has to the grow business or the five victims.
