Trying to locate lost freight - please help

Looking for load that was picked up in Sidney, Ohio going to ProTrans in Laredo, Texas. October 2, 2018.
8 pallets total. Driver did not sign company name or legible signature. Used Xtra Lease trailer. Tractor has S 031 on top of cab. Have photos but blurred. Signature looks like Ernesto. Any help would be greatly appreciated.

 

Here is a picture of the truck involved.

 

are we talking south of the border as in Mexico? Would they be able to lease a trailer in the U.S.?

 

They gave the name of Dayton Freight (subject to Change). They often change without giving us a carrier name. Guy comes in says he's here to pick up for Laredo. Our guy loads him and we find out later that it was set up with another carrier (Captain Express). Captain shows up, freight has already been loaded on the previous truck. When we go to find information on the bol we find no carrier name and the driver signed Ernesto. The load has not shown up at destination and now we have no way of tracing it. We are only a third party warehouse so freight belongs to our customer - who is NOT happy at all.
