The National Transportation Safety Board tells Big 2 that they interviewed the driver of the flatbed truck that was involved in the fatal November 15, 2012 accident.
The N.T.S.B. couldn't go into detail regarding the interview, which occurred on February 20th.
However, agency officials say that the N.T.S.B. will be releasing all of their findings on the investigation this spring.
The N.T.S.B. released a preliminary report on the crash on December 5th.
Four military veterans were killed -- and 17 other people were injured -- when a Union Pacific freight train plowed into a Smith Industries flatbed trailer near the intersection of West Front Street and South Garfield Street around 4:36 PM on November 15, 2013.
The flatbed trailer was carrying 12 military veterans, their 12 wives and 2 escorts from downtown Midland to a banquet at the Midland County Horseshoe Arena when tragedy struck.
The City of Midland has determined that the Show of Support Parade that the flatbed trailer was involved in operated without a permit.
Now, the Midland City Council is looking to beef up their parade permit ordinances
Several victims -- and the families of deceased victims -- have filed or joined in various civil suits against Union Pacific Railroad and Smith Industries.
Union Pacific recently filed motions in civil court that seek to name the City of Midland, Midland County and the Show of Support Organization as responsible third parties in the fatal cash.
Union Pacific is claiming that the 3 entities named in the motions failed to exercise proper care leading up to the Show of Support Parade.
A Midland County grand jury heard testimony about the accident on January 9th and February 6th.
The grand jury will meet for a third time on March 6th.
Jurors are expected to issue a report on the tragedy in early March.
Jurors have already decided not to file criminal charges against Dale Wayne Hayden.
Hayden, 50, was driving the flatbed trailer that was struck by the train.
