Ana Iongi often worries about the day her son will ask the one question she can't answer - "what happened to dad?"
Iongi's partner and the father to her young son, Reginald Sharma, died in August 2017 after a single punch at an Auckland party. The man accused of causing his death was found not guilty by a jury earlier this month.
Sharma who was of Tongan and Indo-Fijian descent was 25 years old when he died and Iongi was seven months pregnant with his child.
"It's tough raising a baby without him," Iongi said, "I still don't know how I'm going to explain to my son what happened, it's hard to explain because I feel like I still don't have answers."
The details of what happened the night Sharma died are still a mystery to Iongi and his family.
Sharma had been at a house party on Haughey Ave, Mt Roskill, in the early hours of August 19 last year.
There were reports of rowdiness and fighting and when police arrived around 3am, they found Sharma lying in the driveway in a critical condition.
"I knew he was going to a party that night," Iongi said "but I thought he meant clubbing not a house party, Reg was a very private person, so even though I was his partner there was a lot I didn't know about him."
Carlos Pula, 23, was charged with manslaughter less than a week after Sharma's death and was accused of delivering a single, fatal blow.
The Crown claimed the punch swung Sharma's head around and split an artery, while the defence argued it was a case of mistaken identity as Pula could not have thrown the punch due to a wrist injury.
Pula was found not guilty just five days before the one year anniversary of Sharma's death.
Iongi said she was "absolutely shattered" when she heard the verdict read out at Auckland High Court.
"I was there every single day, I wanted to punch the walls and scream, if Carlos wasn't the one who hit him I want to know who did. Even if they didn't mean to kill him they meant to hurt him and whoever did that needs to be held accountable for what they did.
"My son will never be able to see his dad, we can't just put him back together, he's gone, and I'll fight hell and heaven to find out who did it so we can be at ease."
Iongi keeps a memorial for Sharma and her son, who died in the same year, in the lounge of her home. It's adorned with pictures of Sharma as well as a t-shirt and possessions.
"He's gone but he's not forgotten in our home, I'm very protective of the memorial," Iongi said.
Iongi believes the truth will eventually come out but she wants it to be before her son is old enough to start asking questions.
