A body found Monday may be that of missing University of Minnesota student Anarae Schunk, and authorities have asked the 20-year-old’s family to provide dental records so they can determine if it is her.

Rosemount police have not told the family whether the missing body is Schunk’s, but they have told them that Anarae, who has been missing since Sept. 22, is most likely dead.

“I know there have been other bodies that have been found, but they haven’t asked us this, so it makes it a high interest to us,” Anarae’s brother, Tyson Schunk, told the Minneapolis Star Tribune, referring to the request for dental records.

The body was found near Lonsdale, Minn., about 30 miles from where Schunk was last seen at a bar in Burnsville with her ex-boyfriend, Shavelle Chavez-Nelson, and his girlfriend, Ashley Conrade. Schunk’s ex-boyfriend is accused of murdering a man outside Nina’s Grill at around 2 a.m. the day Anarae went missing.

Tyson Schunk said his family is still holding out hope that his sister will be found alive despite the grim news.

“What I want is for her to be here and alive. But if it’s her body, we would rather find her and have closure,” he told the Star Tribune.

A bloody jacket belonging to Anarae was found Monday, according to CBS Minnesota. Police told the television station that the jacket was punctured 18 to 20 times, which may indicate stab wounds.
