Police in Georgia have arrested a seventh person related to the death of a Korean woman found beaten and starved in the trunk of a car outside a sauna last month.

Investigators say Sehee Cho, 33, was lured from South Korea by a group calling itself “Soldiers for Christ” in the summer and then dumped in the trunk of a Jaguar in the parking lot of Jeju sauna in Duluth, as CrimeOnline reported.

Police arrested six people, including a 15-year-old boy, and charged them with felony murder, imprisonment, tampering with evidence, and concealing a death.

Gwinnett County Police announced the arrest of Mihee Lee, 54, on Wednesday. She faces the same charges plus false statements. Mihee Lee is the mother of three of the other suspects: Juoonhyum Lee, 22; Joonho Lee, 26; and Junyeong Lee, 15.

Also charged in the case are Eric Hyun, 26; Gawom Lee, 26; and Hunji Lee, 25. All of the original suspects are U.S. citizens except for Gawom Lee, who was visiting the others from South Korea.

Investigators said they believe Hyun drove the Jaguar to Jeju, parked it there, and had a family member pick him up and take him to the hospital for treatment for an unrelated injury. Then, he sent the family member back to the car to retrieve a personal item. That person found the body and called 911.

Detectives said the investigation led them to a home in Lawrenceville where brothers Juoonhyum Lee, Joonho Lee, and Junyeoug Lee lived, along with Hyun, who is not related. Hyunji Lee is the girlfriend of one of the suspects.

Cho was held in the basement of the home, they said.
