L'ORIGNAL, Ont. - An eastern Ontario doctor facing a first-degree murder charge had his case adjourned for two weeks after a short court appearance Tuesday.

Dr. Brian Nadler is accused of killing Albert Poidinger, 89, who lived in Pointe-Claire, Que., at the Hawkesbury and District General Hospital.

Ontario Provincial Police say they were called to the hospital on March 25, after which Poidinger was declared dead and Nadler was arrested.

Police have said they are investigating Nadler in connection with several other deaths at the hospital.

The prosecution says they continue to provide disclosure to Nadler's defence team.

Nadler's lawyer says his client maintains his innocence.
