Police were continuing their efforts to find the body of the 20-year-old Burnsville woman who was last seen Sept. 21 at Nina's Grill in Burnsville with her ex-boyfriend, Shavelle Chavez-Nelson, also known as Anthony Lee Nelson, the Minneapolis Star Tribune reported.
Chavez-Nelson is jailed on charges he killed another man, the newspaper said.
Her brother Tyson Schunk said police visited the family's home Friday night and when asked how certain they were his sister was dead, they said "we wouldn't be here if it wasn't 100 percent."
"It's gut-wrenching," he said. "It's hard to stomach. But we're here together."
Friends said Schunk and Chavez-Nelson had broken up almost a year ago but she had gotten back in touch with him to try to get back $5,000 she had loaned him.
Chavez-Nelson, 31, of Eagan, was arrested Tuesday and charged Thursday with shooting Palagor Obang Jobi, 23, of Savage, to death early Sunday in a parking lot after they'd gotten in a fight. Police allege Nelson was angry because Jobi had talked to his girlfriend, Ashley Conrade, 24, of Rosemount.
Conrade has been charged with aiding an offender for allegedly harboring Chavez-Nelson at her townhouse.
Chavez-Nelson served prison time for first-degree aggravated robbery. He also has convictions for drug sales and weapons violations, as well as misdemeanor driving infractions.
