YONGSAN GARRISON, South Korea — South Korean officials asked Wednesday for custody of a U.S. soldier who allegedly killed a 22-year-old woman in a drunken driving crash Thanksgiving weekend.

An arrest warrant for Sgt. Jerry Onken was issued by a South Korean court Tuesday. South Korean officials said the base has five days to turn him over.

U.S. Forces Korea spokeswoman Lee Ferguson said Wednesday it hasn’t been determined when Onken would be turned over.

Originally, the U.S. military asked to try Onken; the South Koreans denied that request.

When he is turned over, South Korean prosecutors must charge him within 24 hours, said Kwon Jong-hun, a prosecutor with the Justice Ministry.

Onken will be the first U.S. soldier held by South Korea before a trial. Revisions to the Status of Forces Agreement two years ago allow for South Korea to have pretrial custody in a dozen specific crimes as long as other conditions — such as access to an attorney and a preliminary hearing — are met.

Onken will be held in the Seoul Detention Center once he is handed over, Kwon said.

Onken, who belongs to the 143rd Air Defense Artillery Battalion, remains restricted to Suwon Air Base, although military officials have taken him to South Korean police and prosecutors in Suwon for questioning, as required under SOFA.

Military authorities arrested Onken after the Nov. 28 accident and charged him with fleeing the scene of a fatal accident under the Uniform Code of Military Justice.

Ki Kyong-sun was killed after Onken’s car allegedly struck the compact car she was riding in. Four other passengers in the car were treated for injuries. South Korean police said it’s believed Onken ran a stoplight.

Independent blood tests by South Korean and American authorities showed Onken’s blood alcohol level at .06 percent, above the country’s legal limit of .05, Korean police said. Base officials would not confirm the figure. The blood was drawn about six hours after the accident, officials said.
