Butcher reportedly finding transport for winter (6)
I believe the answer is:
sleigh
'transport for winter' is the definition.
(transport used in snow)
'butcher reportedly' is the wordplay.
'butcher' becomes 'slay' (both can mean to murder).
'reportedly' shows a homophone (sound like).
'slay' sounds like 'SLEIGH'.
'finding' acts as a link.
(Other definitions for sleigh that I've seen before include "Dancer pulled this" , "transport (with bells on!)" , "transport in snowbound area" , "Vehicle suitable for snow" , "Horse-drawn sledge" .)
