Friends in Slovakia said David Cerven was a "cool guy" and really excited about coming to New Zealand.
David Sivak was a childhood friend of Cerven and the pair trained together at the Dolnokubínská kickboxing club.
He found out about his friend's death on Facebook, according to target="_blank">Slovak news reports
"I remain shocked. We knew each other since childhood. From fourteen we were very good friends. Cool guy," said Mr Sivak, according to a translation. "He was really excited [about] New Zealand. "
David Cerven later transferred to the Sazuki kickboxing club in Liptovsky Mikulas
Head of the club Peter Miller was also surprised by his former protégé's death, and said Cerven was a "smart athlete, chummy type" who loved to travel.
Hailing from a small town in Slovakia, Cerven was a kickboxer who dreamed of making it big in America.
His father died when he was young and his family didn't have the money to send him to the United States as an exchange student, but he made it as far as Australia and then New Zealand under his own steam.
No one in the Auckland fighting scene had heard of him yet, but he was finding his feet as an apprentice for a roofing and plumbing company on his 12-month working visa.
But it all ended in Myers Park on Sunday night, the 21-year-old calling 111 after he was named by police as a suspect in three aggravated robberies on the North Shore.
The first was on a Sunday night, the week before the fatal shooting, when he allegedly held up the Harbour City liquor store in Glenfield.
Duty manager Jung Kun Ahn said the robber spoke with a "Russian" accent and appeared calm as he demanded cash with a large knife.
"It seemed like he had done this before."
A few days later, police suspect Cerven struck again at the Thirsty Liquor store.
"I opened the till slowly, hoping for someone to come in as it is usually a busy time," owner Deborah Wang said. "But I think I was too slow so he started to grab the cash himself."
He ran off with about $400.
But it was not until Saturday night when Cerven allegedly robbed a dairy in East Coast Rd that detectives from the Waitemata CIB found a clue to his identity.
Cerven had "left evidence" at the scene and police put out a press release the following day, publishing his name and image in the hope that someone would recognise him.
A little over six hours later, he gave himself up. Cerven called 111 at 7.23 on Sunday night to say he was in Myers Park and wanted by police for the aggravated robbery.
Some have speculated that Cerven had a death wish, that he wanted to be shot by police in a "suicide by cop" scenario.
But all Superintendent Richard Chambers, Auckland's top cop, would say is Cerven insisted that police come to the park, rather than walk a few hundred metres to the nearest police station.
"When he was located he told the officers who engaged with him verbally from a distance that he was armed," said Mr Chambers at a press conference yesterday morning.
"Consequently, unarmed staff retreated and requested armed officers to attend."
The
Herald
understands that two armed officers then approached Cerven and believed he was carrying a firearm.
"They have both assessed the situation as an immediate fatal threat and discharged their weapons around the same time," a well-placed source said.
Police have not confirmed whether a weapon was found, or how many rounds were fired by the pair.
Witnesses have described hearing as many as five gunshots, possibly more.
A post-mortem examination has since been completed and the results could be released as soon as today, confirming how many bullets struck the 21-year-old.
The entire episode was recorded on CCTV and the tapes will be the key evidence for three inquiries into his death: two conducted by the police - homicide and internal procedures - and a third by the Independent Police Conduct Authority.
ESR scientists, a specialist search team and CIB staff spent all yesterday in Myers Park, which was still cordoned off last night.
Metal detectors were used to search for evidence, possibly bullet casings, and yellow markers laid down where electronic beeps were heard.
The main search area is about 15 metres down a small hill where a white tent is standing where Cerven fell.
As for what triggered Cerven's alleged activities leading to his death, his colleagues at Topline Trade Services and his travelling companions declined to comment.
"They are all upset as you can imagine," honorary Slovak consul Peter Kiely said after meeting Cerven's friends yesterday.
"What happened and why is very unclear. It is a police investigation and the police are endeavouring to work out what happened."
In his first high-profile case since he took charge of Auckland City district, Mr Chambers said staff on Operation Delaware were working hard to find witnesses and speak to Cerven's family in Slovakia.
"However, it will be some time before we will be in a position to discuss what answers our inquiries today may have provided to the myriad questions."
