Unknown Substance Analysis Results:

Grace: I analyzed the sample from that can of deicing fluid you found in your victim's aircraft hangar, . Now before I begin, let me tell you about this product.

Grace: Deicing fluid prevents clouds' water droplets from turning into ice. Without the fluid, the pilot could lose control of the plane.

Grace: But I studied the composition of this product you gave me, and it's clearly NOT deicing fluid!

Jones: What is it then?

Grace: This fake product is in fact a mix of chemical products that actually froze the stunt plane quicker! Not only did it cause the plane tail to snap clean off...

Grace: ... but the freezing cold must have affected the circuit board, causing a spark that made the stunt plane explode mid-air! With such a sabotage, Walter didn't stand a chance!

Grace: You're facing a smart killer, : for them to have created such an ingenious product, they must really master chemistry!

And actually, the murder weapon IS "Fake Deicing Fluid" not only "Deicing Fluid".
