The FBI is currently investigating the deaths of four friends who were killed and dumped into an SUV that was later found in a cornfield.

The incident was reported in Minnesota on Sunday.

Authorities say the friends were last seen at a bar in St. Paul on Saturday night, and may have left with someone before their bodies were discovered about 65 miles away from the bar.

Officials have identified the victims as 30-year-old Nitosha Lee Flug-Presley, 30-year-old Jasmine Christine Sturm, 26-year-old Matthew Isiah Pettus, and 35-year-old Loyace Foreman III.

According to the report, all of the victims were shot to death and none of them have any ties to the area in which they were found.

“That is the mystery,” Damone Presley, Sr.  Flug-Presley’s dad told reporters. “Hopefully, through the investigation we’ll get that answered,” he said, adding that the whole thing “just doesn’t make sense.”

In a Facebook post, police reported that they have surveillance video of the black SUV stopping at a gas station before it was discovered in the cornfield two hours later. Authorities also reported that another dark colored vehicle may have been following the SUV.

While many of the details surrounding the case are unknown at this time, officials say that they did not believe the murders were due to drug activity or organized crime.
