Homicide Squad detectives are assisting local investigators as they try to determine exactly what happened in the lead-up to a seven-week-old being found unresponsive at a Western Sydney home.

An investigation is under way into the suspicious death of a baby boy at a home in Sydney’s west.

Homicide Squad detectives are assisting local investigators as they try to determine exactly what happened in the lead up to a seven-week-old being found unresponsive at a home in St Marys at 4.15am on Saturday.

Neighbours on the quiet street said they were woken by the flashing lights of police cars and ambulances, and were shocked to hear that a young child had died.

“There’s a young couple that live there, probably in their mid to late 20s, I think they moved in two or so years ago,” one local said.

“On Saturday I woke up to flashing lights, police cars and ambulances everywhere, then my neighbour who owns the granny flat out the back told me that the newborn baby had died.

“He said there had been nothing out of the ordinary, it is all very shocking.”

Another neighbour said he heard a “squabble” over 24 hours after the baby was pronounced dead.

An property owner on the same street was working in his yard as police investigators and forensic specialists inspected the home next door.

“I knew the young couple, he is a nice guy, the dad,” he said.

“The mum is really nice too (although) there was a bit of shouting this morning between (her) and another person who was there.

“I heard yelling. There was a squabble.”

The occasional resident was seen leaving their home on an otherwise eerily quiet street on Saturday while police “made a few trips in and out.”
