An 83-year-old Canadian who admitted to killing his wife inside a Waikiki condominium stabbed the woman at least 100 times, prosecutors said Thursday.

Circuit Judge Derrick Chan granted the prosecution's request to hold Tadeusz "Ted" Jandura, of Edmonton, without bail. Jandura is charged with second-degree murder in Sunday's slaying.

His 82-year-old wife, Ingeborg Jandura, was found dead by police responding to an argument complaint at the Ilikai.

Jandura, who answered the door at the unit, admitted to police, "I just killed my wife," according to Lt. David Kamai.

Ingeborg Jandura died of stab wounds to the neck, lung and heart, the city medical examiner's office said.

The Janduras, who had been married 58 years and coming to Hawaii for many years, had been in the time-share unit since Dec. 12 and planned to return home in March, officials said.

Jandura is believed to be the oldest person charged with murder in state history.
