Theft from ruined crypt, neatly muffling echo (5,7)

I believe the answer is:

petty larceny

'theft' is the definition.
(petty larceny is a kind of theft)

'ruined crypt neatly muffling echo' is the wordplay.
'ruined' indicates anagramming the letters.
'muffling' indicates putting letters inside.
'echo' becomes 'e' (phonetic alphabet: alpha, bravo, charlie etc.).
'crypt'+'neatly'='cryptneatly'
'cryptneatly' is an anagram of 'pttylarceny'.
'pttylarceny' going around 'e' is 'PETTY LARCENY'.

'from' acts as a link.
