The investigation, on the assumption it was arson, continues.

Fire investigators confirmed Wednesday they are treating last month's spectacular Sacramento trestle fire as an arson -- but warned that despite a sense of urgency for a breakthrough, the investigation is laborious and could go on indefinitely.
"It's an arson investigation," Sacramento City Fire Marshal Troy Malaspino said. "There is little in the way of forensic evidence, so we are going to have to solve it primarily through witness interviews and reconstructive timelines."
The March 15 fire consumed a section of a key Union Pacific freight mainline connecting the West Coast with the rest of the United States. The line also serves several passenger trains.
