Then the government took steps to locate and bring home her entire skeletal remains, including by having the bones brought through a third country. Ms. Mizell said two F.B.I. agents in April 2023 escorted the remains back to the United States draped in an American flag.
A copy of the autopsy report the F.B.I. gave her showed that her sister had been shot in the head and her skull crushed. Agents also presented her with an urn of ashes and an American flag. The agents also returned the personal journals Cydney kept during her time in Afghanistan.
“Without the agents, we would still be in some big black hole of nothingness,” Ms. Mizell said.
In October, Ms. Mizell’s family held a memorial at a Baptist church in Tacoma, Wash., where her father was once the pastor. Dozens attended the service, including F.B.I. agents. The American flag Ms. Mizell had received was on display.
Her family is expecting to finally receive an official death certificate.
Ms. Mizell said her sister, who would have turned 66 next month, sought to improve the lives of those around her.
“She was devoted to loving and helping people around the world, especially supporting women and girls in desperate situations,” she added.
Other kidnapping cases have continued to frustrate the F.B.I. In Afghanistan, investigators are still trying to track down Paul Edwin Overby Jr., an author who officials say was last seen in May 2014 in Khost city while researching a book. He had hoped to interview the leader of a militant network when he went missing. And Ryan Corbett, of Western New York, was detained by the Taliban in 2022 after visiting northern Afghanistan on a business trip.
