Authorities said Wednesday the man found dead along railroad tracks in western Minnesota was a passenger on an Amtrak train headed for Chicago.
The Clay County sheriff's office is waiting for preliminary autopsy results from Ramsey County to determine how 27-year-old Jared Nilles died, the Forum said.
Clay County investigators were en route to the Twin Cities today to meet with Minnesota Bureau of Criminal Apprehension agents working on the case, Clay County sheriff Bill Bergquist said.
Authorities are also checking whether the train had security cameras, the Pioneer Press said.
"I don't know if we'll ever know exactly what happened unless somebody saw something," he said.
BNSF railway contacted the sheriff's office around 7 a.m. Monday after a train conductor spotted Nilles' body along the tracks near Buffalo River State Park, the Forum said.
Nilles graduated from Fargo South High in 2003 before studying screenwriting and film production at Minneapolis Community and Technical College.
