A DISTRAUGHT mum whose four-year-old son was killed in a murder-suicide by his dad wrote: “I’m so sorry I couldn’t save you”.
Natsuko Kurihara posted the heartbreaking message to her “beautiful boy” Koah who was found dead at a house on Friday.
Police found the bodies of Harvey, 46, and his son at the home in Rossville, Queensland, Australia.
In a devastating post to Facebook on Saturday, Ms Kurihara said: “’My beautiful boy Koah, he has had only four years of life, this has been taken by his father. He then took his own life.
“I’m in pain life is not fair. Let the people you love know you love them as they can be taken from you.
“I’m so sorry Koah l couldn’t save you. Love you forever.”
Koah’s dad, Troy Harvey, had posted about his battles with mental health just weeks before the murder-suicide.
In July Mr Harvey, who was a boxercise teacher, revealed he had suffered through a “full on nervous mental breakdown”.
He wrote: “I am so sorry to all the people I have hurt or let down over the years due to excessive drug and alcohol abuse.
“I am seeking help, so come on down get fit.
“Let’s support those with mental health issues, past traumas, or anything else that seems to pull us down and feel like know where to run to.”
Police discovered the bodies after they were called to the home after a 36-year-old woman reported she had been attacked by Harvey the previous night.
Detective Inspector Jason Smith said investigators are looking to speak with anyone who spoke to Harvey between August 28 and September 4.
They also want to speak to the driver of a silver vehicle who visited his home on Friday morning.
“This has been a distressing investigation for all persons involved.”
Insp. Smith said the first people at the scene spent a “considerable amount of time” trying to revive the four-year-old.
A crime scene has been established and detectives have launched an investigation into the circumstances surrounding the deaths of both Mr Harvey and Koah.
Police are awaiting autopsy results to determine how the pair died.
