Christopher Hughes, 37, from Marsh Green, disappeared on Friday, February 18 after he was seen getting into the back of a vehicle on Almond Grove, Worsley Hall.
Police issued an appeal for help to find him, but his body was discovered on White Moss Road South, near the M58 in Skelmersdale, four days later.
A post-mortem examination concluded that he had died from multiple injuries in what had been described as a “frenzied attack”.
