Pretty simple question, but I haven't run into the answer yet despite some searching.
Hypothetical scenario: A TIE Phantom equipped with Fire-Control System and Weapons Engineer shoots at Biggs, and kills him. Wedge is within range 3 of the TIE Phantom.
Biggs is destroyed.
Does the Phantom gain a TL on Biggs before he is removed from play, thereby allowing him to gain a TL on Wedge?

I assume that the TIE Phantom does not transiently gain a TL on the ship about to be removed, which means that Weapons Engineer does not trigger, but I couldn't definitively find an answer to the timing.
