Murdered man waited more than an hour for police

A man who was allegedly stabbed to death by his wife waited for more than an hour for his call to Triple-0 to be answered.

A Police Integrity Commission (PIC) is probing the response time and claims of blackspots in the Force's communication network.

On December 16, Kenneth Parker, phoned emergency services from his West Wyalong home near Griffith in rural NSW.

The 50-year-old called at 6.35pm. Paramedics and police did not arrive until 7.45pm - 70 minutes later.

Marianne Parker, 55, has been charged with murder, and is before the courts.

There have been claims that the police radio network has problems across the entire western region.

A police spokesperson told Fairfax "there doesn't appear to be any issue that is currently impacting the performance of the network".

Meanwhile, the NSW Police Association's Mick Connor told the Daily Liberal in February that radios in the area had problems "for years".

"We've been having problems with radio dropping out and having no communications between cars, stations and police radio," he said.
