Two of the people charged with murdering a disabled Featherston man realised afterwards that they had blood on their footwear, a jury has been told.
Four people have pleaded not guilty of murdering supermarket worker Glen Jones, 40.
They and a fifth person are also charged with aggravated burglary of Jones' small flat.
Macaela Coley has been a witness as their trial entered its second week in the High Court in Wellington.
She was the sober driver for a group who went to a party in Masterton on January 11 last year.
People at the party were talking about a woman who had been raped and that nothing was being done about it.
Coley said everyone seemed quite cheerful and she did not think there was much of a plan, but it escalated to the point where two carloads of people drove to Featherston with one car stopping on the way to get "bats".
"They were not acting very malicious, they were just saying something should be done," Coley said.
"I can't really blame anybody for it. It was just everybody started wanting to go."
The other car was in the lead and she followed in her car because she did not know where to go.
"I don't believe any of them would have done anything, to the point I thought they were almost talking s...," she said.
When they got to Featherston she and another woman stayed in the cars while the others left. They were hurrying when they came back but they seemed normal.
Instead of going back to Masterton they drove over the Rimutaka Hill and stopped behind the carwash at an Upper Hutt service station.
Coley said Tariana Jones realised she had blood on her boots and wiped them with tissues and water. Kristofer Jones also wiped his shoes.
"I was a bit freaked out so I got back in my car."
She drove back to Masterton passing an ambulance at the top of Rimutaka Hill and a lot of police cars on the main road in Featherston.
Tariana Hineteanaurangi Jones, 33, Kristofer Lee Jones, 24, Matthew John McKinney, 29, and Hayden Ranson, 28, have pleaded not guilty to murdering Glen Jones.
McKinney and Ranson pleaded guilty to a charge of aggravated burglary of Jones' flat. The other two and Toni Maree Miller, 23, pleaded not guilty to the aggravated burglary charge.
Their trial is continuing.
