Marana police are investigating a package of drugs found on a Union Pacific train that derailed Tuesday.
"Union Pacific Police recovered a package of suspected narcotics from the wreckage," said Union Pacific spokesman Jeff DeGraff in a statement. "There was no identifying packaging. It was turned over to Marana PD for destruction."
Marana police spokesman Chriswell Scott said the department would not comment at this time because it's an ongoing investigation.
In the Tuesday wreck, which happened amid a violent storm, 27 freight cars derailed, closing the I-10 access road westbound, just north of Twin Peaks Road. UPS confirmed that its packages were being carried in some cars that derailed.
The train tracks were operational Thursday. Cleanup in the area continues.
