Witnesses say police and paramedics were so distressed on finding a 21-month-old toddler dead inside a Queensland home they broke down sobbing in the gutter outside.
Police believe toddler Mason Lee died in 'suspicious circumstances' at the Caboolture home early on Saturday morning.
Mason's mother's ex-partner Andrew William O'Sullivan, 35, was questioned for 18 hours on Saturday helping police with their inquiries.
He said the evening had been a 'normal night' until the boy became unresponsive.
“Two police and two ambos did their jobs and then they all just dropped to the gutter. There were ambos sobbing,” a neighbour told News Corp.
“They had to be taken away. They couldn’t deal with what they had seen.”
Queensland police are continuing to investigate how the boy died but have indicated the toddler had injuries on his body.
Mother Anne Lee told 7News her son was a 'beautiful boy'.
Neighbours have started a GoFundMe page for the family in the wake of the devastating news.
"Taken suddenly and far to soon from his loving family. A little ray of sunshine with infectious smile and a love of life.
"We are a group of neighbours that would like Mason to have the farewell he deserves. To help his mum to cope with her pain and grief.
The money raised will be used for Mason's funeral and other expenses for the family.
"The death of Mason should never have happened, an innocent little man taken from this world too early. We would like to see Mason given a funeral befitting his happy nature."
