A man charged with the murder of his estranged wife following a fatal car crash has died while in custody.

A man accused of murdering his estranged wife after the pair were involved in a car crash has died in hospital after being found unresponsive in his prison cell.

Troy Andrew Armstrong, 36, was charged with the murder of Kristy Armstrong, 36.

Kristy Armstrong was allegedly murdered by her estranged husband Troy Armstrong.

Emergency services were called to Speedy St in Molong, near Orange in New South Wales, on June 9 last year after reports of a crash between a ute and a sedan.

Police had alleged Mr Armstrong had driven his ute at speeds of 140km/h towards Ms Armstrong’s sedan as it was travelling.

Two passengers were also in the sedan driven by Ms Armstrong at the time of the crash.

They were each treated for minor injuries by paramedics.

Kristy Armstrong died at the scene of the crash in Molong.

Mr Armstrong was also charged with two counts of attempted murder.

His ute was badly damaged in the crash, with Fire and Rescue NSW needing to extract him from the vehicle.

Paramedics attended to his injuries before rushing him to Royal North Shore Hospital in a critical condition.

In a statement, Corrective Services NSW confirmed Mr Armstrong was found unresponsive in his cell at the Metropolitan Remand and Reception Centre in Silverwater on Tuesday.

A spokeswoman said he was “immediately given first aid and taken to hospital but was pronounced deceased”.

“As a matter of protocol, Corrective Services NSW and NSW Police investigate all deaths in custody regardless of the circumstances,” she said.

Mr Armstrong was due to appear in court in Orange in July for a committal hearing.
