means.
- Blackmail.
- Burglary.

taxmap/pubs/p547-001.htm#en_us_publink1000225209You cannot deduct as a theft loss the decline in market value
of stock acquired on the open market for investment if the decline is caused by
disclosure of accounting fraud or other illegal misconduct by the officers or
directors of the corporation that issued the stock. However, you can deduct as a
capital loss the loss you sustain when you sell or exchange the stock or the
stock becomes completely worthless. You report a capital loss on Schedule D
(Form 1040). For more information about stock sales, worthless stock, and
capital losses, see chapter 4 of Publication 550.

accidental loss or disappearance of property can qualify as a casualty if it
results from an identifiable event that is sudden, unexpected, or unusual.
Sudden, unexpected, and unusual events were defined earlier.
