It's come into focus now why the ATF and numerous local law enforcement agencies in southeast Minnesota conducted planned raids on Thursday.
A release from the U.S. Attorney's Office says the raids were planned to arrest and detain three suspects of a robbery that resulted in the death of a robbery victim.
A federal indictment states that Lennie Dwayne Brooks, 33, of Zumbro Falls, his brother Randy Lorenzo Brooks, 23, of Wabasha, and Autumn Marie Nichols, 20, of St. Paul are each facing one count of interference of commerce by robbery.
The indictment alleges that the trio stole approximately $50,000 in cash from Shaung Hur Asian Markets, which has locations in Minneapolis and St. Paul. The cash was stolen from the owner's home in Eden Prairie in October.
As a result of the home invasion, Oukham Oudavanh, 63, the owner of Shaung Hur Asian Markets, died of a heart attack.
The three suspects have not been charged in connection to Oudavanh's death.
The raids were carried out in areas surrounding Rochester on Thursday morning in what the St. Paul branch of the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) called a "planned operation."
All three suspects were scheduled to make their first court appearance on Friday afternoon.
