A MAN is on "suicide watch" after allegedly using a car tow ball to bash his wife to death.
Trevor Ernie Zischke, 53, faced Brisbane Magistrates Court on Thursday charged with murdering his wife Noni at their Bracken Ridge home on Wednesday.
He was captured in a dramatic interception on the Bruce Highway near Caboolture during the afternoon.
Police are expected to allege Zischke bludgeoned his wife in the head with the tow ball before stabbing her with a knife.
Lawyer Adam Magill, engaged by the Zischke family on Wednesday night, said outside court his client was "not in a good way".
He said Zischke was on "suicide watch" and the matter was likely to go to the Mental Health Court.
"He's in a terrible state, both emotionally and physically devastated," he said.
"It's a tragic end to a very long relationship.
"The facts are very sketchy at this point.
"It does appear the intention was to end his own life but he couldn't get to that stage.
"I think there's definitely some mental health issues there.
"It's hard to get instructions."
Police were called to the Bracken Ridge home on Wednesday morning and intercepted Zischke on the Bruce Highway near Caboolture soon after.
Mr Magill said his client was unlikely to make a bail bid in the supreme court.
The case was adjourned to June 4.
