A woman has been stabbed to death in front of her children in an alleged domestic violence attack at her home in central Queensland.
Her attacker, believed to be her husband, remains in Rockhampton Hospital with self-inflicted wounds.
Police and paramedics were called to the Rockhampton address where the 42-year-old woman lived about 6.30pm on Tuesday.
The Seven Network identified the victim as Karen Gilliland and the attacker as her husband Nigel Gilliland, 45.
She was was found with "horrific" wounds and could not be saved, police said.
Two of her three children were home at the time of the attack.
"It's a horrific scene for all included, especially those children to see that happen to their mum," Acting Inspector Luke Peachey said on Wednesday.
"We've been police officers for a number of years and this is one of the worst things we've seen.
"Three children have lost a mother, a father and mother have lost their daughter ... so it's an absolutely tragic event."
Her attacker was found two hours after emergency services were first called to the house.
He is in custody in hospital undergoing surgery for non-life-threatening wounds.
Insp Peachey would not confirm if the man was the children's father or if the attack was domestic violence.
He also would not rule out the possibility the man was under the influence of drugs at the time.
Police believe they found the "sharp-edged" murder weapon at the crime scene but are awaiting forensic test results.
No charges have been laid and police are expected to interview the man in hospital when he has recovered from surgery.
