"I grew up with Allan. I've known him since we were probably about 8 or 9 years old and we have an intermediate school here in Waitara and that's where I became, not mates, but brothers with Snow Rowe, Allan."
O'Carroll said even as they got older he and Allan, who was 54 when he died, were inseparable.
"Snow was the cool mate that everyone has, you know. Everybody had a cool mate where he's got the V8 cars, he's got the Harley-Davidson bikes and stuff like that. To me, he was my coolest mate.
"And he was forever getting disqualified from driving, especially when we were playing sports together, so I always got to drive his Holden Premier with the big blower coming out of the bonnet. It was the deadliest car in Waitara."
A talented sportsperson, Rowe was a member of the all-conquering Waitara Bears rugby league side in the 80s and represented Taranaki in the 13-man code as well as being a skillful touch-rugby exponent and softballer.
O'Carroll said he was a tough competitor.
"You know a lot of people didn't like playing against Snow because he was tough, you know. He went out there to bend you over, hit you hard and run over the top of you.
"Although he was one of the quickest in the team instead of running around you, he just run over the top of you.
"I reckon he was a bit of a superstar, really. He was as just as good as Dave Watson and Tony Kemp [who made the Kiwis side] and all that, but obviously he's had other things . . . he's had a million things on his mind and was doing a million other things."
O'Carroll said the friends had drifted apart in recent years over Rowe's drug use.
"Snow go into a bit of trouble with drugs and stuff like that and I despise that . . . and so I didn't really see Snow the past five or six years as maybe I should've.
"You know, maybe I should've been doing a buddy check with him more often, but I think it was because he was doing harder drugs maybe that he stopped coming around and I stopped going around there. So we didn't stay tight."
O'Carroll said there had been a strong reaction in Waitara to the mechanical engineer's death.
"Obviously it brings up memories of things like Steven Wallace and a lot of people are saying it's bulls**t and the cops are this and the cops are that. And turning on the police a bit.
"But they don't seem to realise, you know, our mate had a gun and if you're producing a gun you've got to be prepared to be shot."
Wallace was shot and killed by police in April 2000 after challenging police with a golf club he had been smashing shop windows with on Waitara's main street.
O'Carroll said the fact Rowe had not managed to get out of the driver's seat of the stolen vehicle he was in when he was shot did not make much difference.
"It's a hard one cause that's all I've heard too. So he was in the car, but from what I hear they warned him four times and as soon as he's grabbing the gun and they see a gun . . . you know.
"Snow was more than a mate to me, you know, he was my brother, but when he's doing things like that, you know, the cops have got to . . . and I think the cops responded how they should've. They've got a job to do and they did it.
"Even though I love my mate and he's my brother and that . . . he just shouldn't have. I think he was just in a bad headspace, you know, and maybe I could have, if I had gone and seen him more often and talked to him, maybe we wouldn't be in the situation we are in.
"I cried for a couple of hours when I found out but it's just a real hard one. And you've got to think about the cops who actually shot him as well. It's not something you are going to do until you have to and I just feel for them as well."
O'Carroll said he expected Snow, whose body was expected back at his Brixton home, would get a huge send-off.
"Obviously we've got to abide by the Covid thing, but I'd say probably half of Waitara will probably turn out even though you are only allowed 50 there. But as long as they keep that distancing sorted there's no reason there couldn't be 200, 300 or 400 people there. There might be just one big line of people halfway down to Waitara there."
The four officers involved in the shooting of Rowe have been stood down for 10 days and their weapons retained for ballistics examination. The cutdown .22 rifle carried by Rowe will also be tested to see if it was fired.
A Critical Incident Investigation into the shooting of Rowe is underway and the Independent Police Conduct Authority has been notified.
The death has also be referred to the Coroner.
