MARANA, Ariz. (AP) - A train derailment on the outskirts of Tucson is being investigated by authorities after drugs were found in the wreckage.
Union Pacific spokesman Jeff DeGraff told Tucson News Now Friday that a package of "suspected narcotics" was turned over to Marana police.
A police spokesman did not immediately return a call seeking comment.
Trains were allowed Thursday to use both sets of Union Pacific tracks where 27 freight cars derailed along a main route between Texas and California.
The cars derailed Tuesday during a heavy rainstorm. DeGraff says further information on the cause wasn't available.
DeGraff previously said the derailed cars carried consumer and manufactured goods but that no hazardous materials were released or involved in the derailment.
