The Minnesota National Guard will release the names of the deceased crew members on Saturday.
The pilot from the 8th Fighter Wing suffered minor injuries when he ejected during a landing after a routine sortie Monday.
The condition of the National Guard members aboard remains unclear.
The National Guard lost contact with the helicopter shortly after it took off on a maintenance test flight from St. Cloud.
The unidentified pilot was transferred to a local medical facility after sustaining minor injuries.
The mishap occurred at approximately 9:10 a.m. during a routine training event and required emergency personnel to respond.
Data from the watch shows he died less than an hour before his body was recovered.
A preliminary report by the National Transportation Safety Board appeared to rule out some factors in the crash.
Maj. Trevor Joseph, commander of Charlie Company, 1st Battalion, 5th Aviation Regiment, was killed during a helicopter crash.
