A man accused of being involved in the fatal bashing of a Wairarapa supermarket worker had no idea a member of his group could turn into a "homicidal maniac", a jury has been told.
Kristofer Jones, 23, is one of five people standing trial in the High Court at Wellington over the attack on Featherston man Glen Jones, 40, last January.
He and three others - Tariana Jones, 33, Matthew McKinney, 29 and Hayden Ranson, 28 - have denied murdering him.
Toni Miller, 23, has pleaded not guilty to a charge of aggravated burglary with a wooden bat and axe handle in relation to the attack.
The Crown's case is that Mr Jones was attacked by the four defendants charged with murder, while Miller waited on the street.
