As I recall he just got her drunk and stole the evidence...?
Jeannie T was working late, and then was stuck waiting for Clint to pick her up. It's not entirely implausible that Melanie might have to cover a short shift - one of the buildings where I work has 12-hour nursing shifts, but when there's a call in, sometimes coverage only has 8-10 hours, so someone comes in for 2-4 hours...of course in Salem people only work when it serves DA PLOT. But at least Melanie was dressed appropriately for her job!!!
I thought Jeannie T dropped the W-2s in a mail slot - but if it was the trash, I'll forgive the writers a lot if that comes back to bite her in 2-3 weeks when Maxine, Dr McScruffy, and our Sleeveless Archduchess of Haggery start wondering about their tax info!!!
