In roundworms smuggling case, Chinese citizen to be held in detention for now
A Chinese citizen accused of bringing biological materials related to roundworms into the country for her work at a University of Michigan laboratory has agreed to remain in federal custody.
Chengxuan Han is charged with smuggling goods into the United States and making false statements. She appeared in U.S. District Court in Detroit on June 13, two days after an initial detention hearing was adjourned so her attorneys could have more time to review material regarding issues pertinent to bond. Han has been detained since she made an initial appearance June 9.
One of her attorneys, Sara Garber, told the court that "(t)his is a constantly evolving situation involving a large number of factors" including the criminal charges, implications on Han's professional career, considerations in the U.S. and China, a language barrier and a need for an interpreter.
"This situation is fluid. My client consents to detention without prejudice to remain in federal custody at this time," Garber told the court. "We have been working diligently on this matter."
Garber had no additional comment after the hearing. A preliminary exam is set for June 30.
Han appeared in court wearing an orange jumper with Sanilac County written on the back. Her dark hair was pulled back in a ponytail and she wore thin eyeglasses. Her hands were handcuffed in front of her.
Han had a Mandarin Chinese interpreter, but spoke some English when answering yes or no questions posed by Magistrate Judge Elizabeth Stafford. Han put a tissue to her nose toward the end of the hearing and could be heard sniffling.
She is pursing a doctoral degree from the College of Life Science and Technology in the Huazhong University of Science and Technology in Wuhan, China, according to a court filing.

Feds: Chinese citizens charged with smuggling harmful fungus for research at U-M
From September 2024 to March, the records indicated, she was listed as the sender of four packages of concealed or mis-manifested biological material addressed to two people associated with a lab at U-M. The packages did not contain the correct documentation and were not imported per U.S. Department of Agriculture or U.S. Customs and Border Protection regulations, according to an affidavit.
Han arrived at Detroit Metro Airport from Shanghai on a J-1 visa June 8 and customs officers conducted an inspection and interview. She denied sending the packages to members of the lab, according to the affidavit, but when pressed, admitted to shipping them, with the materials from her research lab at the Chinese university. It indicated the packages contained plasmids and petri dishes of C. elegans (nematode worms).In a separate case earlier this month, Yunqing Jian, 33, and her boyfriend, Zunyong Liu, 34, were charged with conspiracy, smuggling goods into the United States, false statements and visa fraud. They are accused of smuggling a fungus that causes a disease in wheat, barley, maize and rice so that Liu could research the pathogen at a U-M lab where Jian works.
Jian agreed June 13 to be detained during a detention hearing in federal court. Liu is accused of smuggling the fungus, identified as Fusarium graminearum, into the country at the airport in clear plastic baggies in his backpack July 27. Customs officers denied him entry and processed him for expedited removal back to China, according to an affidavit.

Suspected killer of Minnesota lawmaker is a doomsday 'prepper' with 'bailout' plan
Recently unsealed court filings reveal how Vance Boelter was preparing himself and his family for a catastrophic event. Police found his wife with two guns and around $10,000 in cash. The man suspected of killing a Minnesota lawmaker and her husband in a brazen attack while dressed as a police officer is a doomsday "prepper" who set aside passports, guns and hordes of cash in the event of a catastrophe, newly unsealed federal court documents show. Vance Boelter's wife relayed the doomsday plans after she was interviewed by police during a manhunt for Boelter after he allegedly shot four people on June 14, according to the complaint filed in U.S. District Court in Minnesota. "During an interview, Boelter's wife identified that she had recently received a group text message from Boelter in a group text thread with their kids," FBI Special Agent Terry Getsch wrote. "The text stated something to the effect of they should prepare for war, they needed to get out of the house and people with guns may be showing up to the house." Law enforcement stopped Boelter's wife while she was traveling with her four children to visit friends northwest of the metro area, the federal complaint said. In the car, officers found a safe, all of the children's passports as well as Boelter's, about $10,000 in cash, a revolver pistol in the glove box and another semi-automatic pistol in a cooler, the FBI says in the complaint. Boelter, 57, is accused of killing state Rep. Melissa Hortman and her husband, Mark, and seriously wounding state Sen. John Hoffman and his wife, Yvette. The new information about Boelter and his family comes nearly a week after the attack that investigators say Boelter "extensively researched" and planned. He compiled a list of mostly Democratic state lawmakers and their addresses; he fitted his SUV with lights and a fake license plate to resemble a police squad car; and he purchased a silicone mask and a cache of weapons, according to a 20-page affidavit filed in federal court. Details about what Boelter's wife was carrying come after federal investigators revealed that Boelter sent multiple texts to her and the children hours after the shootings. In a group chat, he sent the following message at 6:18 a.m.: 'Dad went to war last night … I dont wanna say more because I dont wanna implicate anybody.' Around the same time, his wife received a separate message from Boelter. 'Words are not gonna explain how sorry I am for this situation … there's gonna be some people coming to the house armed and trigger-happy and I don't want you guys around.' Boelter was arrested late June 15 following the largest manhunt in Minnesota state history, authorities said. Federal prosecutors charged him with several counts of murder and stalking. Minnesota authorities say they believe Boelter impersonated law enforcement to gain access to the victims' homes, exchanged gunfire with police and fled on foot outside Minneapolis. Minnesota Gov. Tim Walz called Hortman's killing a "politically motivated assassination." What else to know about Boelter? At various times, Boelter has claimed to work in the food service industry. In other moments, he's claimed he runs large firms involved with 'security situations' overseas, including Africa, Eastern Europe and the Middle East. The recently unsealed court filings said Boelter worked at Red Lion, a 'security company and fishing outfit in Congo, Africa.' On LinkedIn, Boelter called himself CEO of Red Lion, according to reporting by the Milwaukee Journal Sentinel, part of the USA TODAY Network, though the Red Lion website linked to his LinkedIn profile was down and Boelter said he was open to work. He also appeared as a speaker for a Minnesota nonprofit serving African immigrant communities. Minnesota Africans United, a Brooklyn Park nonprofit, said in a statement that Boelter participated in an August 2022 virtual webinar about trade and investment in the Democratic Republic of Congo. Boelter's participation as a speaker was facilitated by a third party, the statement said. He was never hired, paid or contracted by the nonprofit, which had no contact with him since the one-time appearance. A biography for the session described Boelter as having worked in Congo and for a security guard company. USA TODAY previously reported that a LinkedIn page believed to belong to Boelter showed he attended St. Cloud State University. University spokesperson Zach Dwyer confirmed Boelter graduated in 1996. Childhood friend called police on Boelter David Carlson, 59, told Reuters that he has been sharing a house in Minneapolis with Boelter for a little more than a year and last saw him the night of June 13. At about 6 a.m. on June 14, he received a text from Boelter. "He said that he might be dead soon," said Carlson, who called police. Carlson, who has known Boelter since fourth grade, said Boelter worked for an eye donation center and stayed at the house because it was close to his job. Carlson said he feels betrayed by Boelter and heartbroken for the victims, adding: "His family has got to suffer through this." Federal authorities said the Boelter family home was in Green Isle, Minnesota, about one mile from where he was ultimately captured. The Minnesota city of around 600 people is about an hour southwest of the Twin Cities. Green Isle is a small community, Mayor Shane Sheets told USA TODAY. Boelter had no known political involvement or affiliation in the city, he said
