if one entangled particle is "destroyed"

what is the state of the OTHER particle?

Situation 1

two entangled particles, A and B(assume have mass).

if A is "destroyed", say it hit a wall :).

What happen to the B's momentum and location?

Situation 2

two entangled photons, A and B.

if A is "destroyed", assume photoelectric effect.

What happen to the other photon's spin? Would B return to NO SPIN? Keep its spin? or other results?

In a word,

Is "destruction" considered as some-sort-of "measurement"?

Does the wave function, in a destruction, collapse the same way as in a measurement?

What is the mathematical operator for "destruction"(if it is considered as a measurement)?
