A mother of six has been charged after her nine-month-old baby was found dead in a car in Adelaide’s north on Wednesday, as neighbours recall the moment they heard her desperately plead for him to wake up.

Crystal Manneken, 31, was charged with criminal neglect on Thursday after paramedics were unable to revive her son Kohen.

Emergency services raced to the scene in Midlow Road, Elizabeth Downs, about 8pm on Wednesday, following reports that the baby had been found unresponsive.

Neighbours reported Kohen’s parents panicked when they went to check his bedroom and found it empty. They later reportedly found him inside a minivan parked in the driveway.

It is not yet known how long the baby had been inside the car.

Witnesses also say the parents ran door-to-door pleading for help, with Manneken heard begging Kohen to wake up.

A neighbour told the Adelaide Advertiser that she and others gave the baby CPR. 

They managed to restore a faint heartbeat before Kohen later died.

‘They worked on the baby for 10 to 15 minutes before the ambulances arrived,’ one neighbour said. 

Jasmine Hudson told the ABC: ‘There was one big ambulance and three or four four-wheel-drive ambulances and a fire truck and about six police cars. It’s heartbreaking and I feel for the people it happened to.’

Another neighbour added: ‘That is so horrible… I’ve got a grandbaby and two children of my own.’

Photos from the scene on Thursday morning showed a heavy police presence at the home, along with multiple ambulances and a fire truck. 

Baby items, including a car seat, bouncer, toilet potty, and bath, were spotted strewn outside the home.

Manneken, who describes herself online as a stay-at-home mum, is believed to have two sons and four daughters.

A report will be prepared for the coroner as detectives continue to examine the circumstances surrounding the baby’s death.

Manneken was bailed to appear in the Elizabeth Magistrates’ Court on April 14.
