An Adelaide woman is now facing charges following the tragic death of a nine-month-old boy.

According to neighbors, the father of the infant was seen frantically running down the street seeking assistance after discovering his son unresponsive in the family vehicle.

In an attempt to save the child’s life, a neighbor performed CPR until emergency medical personnel arrived on the scene.

The usually quiet Midlow Road in Elizabeth Downs became a hub of activity as emergency services flooded the area shortly before 8 p.m. yesterday.

Authorities have collected CCTV footage to ascertain the duration the infant was left inside the car.

Neighbors reported that the mother claimed the baby had not been in the car for an extended period.

“She said the car was there for about 20 minutes,” resident Joshua Hill told 9News.

Detectives have gone door to door to speak to neighbours.

The heartbreaking death has shattered residents on the street.

“A bit uneasy, especially because it’s a kid and we’re meant to protect them,” neighbour Blair Ross said.

“I’ve got a three-and-a-half-year-old myself, so it was kind of hard to see,” Hill said.

“I’ve got a grandbaby and that’s just horrible,” resident Jessica Edwards said.

A 31-year-old woman from the property was charged with criminal neglect.

She was bailed to face court next month.
