POLICE have found a gun in the wreckage of a vehicle driven by a mother suspected of killing her baby son and wounding her former husband.

The woman, 22, died in hospital after the utility truck crashed into a tree, ten minutes after her eight-month-old baby and a man were shot at a house at Gracemere, near Rockhampton, on Tuesday night.

The woman died of massive head injuries.

Rockhampton police inspector John Wacker said a small handgun had been found in the ute the woman was driving.

"A firearm was located at the crash scene," Insp Wacker told reporters on Wednesday.

Police have spoken to the injured man, 36, who a family friend confirmed as the father of the dead child.

The man was in a stable condition after undergoing surgery for a gunshot wound to the stomach and was no longer under police guard at Rockhampton Hospital, police said.

Police at a press conference on Wednesday said the man and woman divorced last year after only being married for a few months.

Neighbours 'heard gunshots'

Neighbours found the child with gunshot wounds after the man staggered to their door seeking help at 7.50pm on Tuesday.

The boy and the man were taken to the Rockhampton hospital, but the boy could not be saved.

Jodiee Bennett, 35, who lives opposite the house where the shootings happened, said she and her family only heard one gunshot but there was apparently more.

"A man went in there and found the little fella on the floor," she said.

"There was screaming and everything ... because someone had found the baby hurt. They were calling out to get an ambulance.

"They thought he had hit his head on the tiles, but apparently that was one of the gunshot wounds that the baby copped in the head."

She said her own three children were very upset.

"It's really freaked our kids out."

Ms Bennett said her husband, Tex, saw a utility truck being driven away from the home a short time after the gunshot was heard.

"My husband saw a ute backing away," she said.

Detective Inspector Jon Wacker earlier today said the man had staggered to a nearby house for help.

"The person presented himself at that location with a shotgun wound to his stomach," Insp Wacker told ABC Radio.

" ... neighbours of the first residence had entered the dwelling after the female occupant had left and located a eight-month-old baby with a gunshot wound."

A major incident room has been set up at the Rockhampton police station.
