Calgary police confirm officers on the street are keeping an eye out for Dr. Michael Belenky, the former assistant medical examiner.

Belenky is the pathologist whose autopsies are now under review by Alberta Justice for possible errors.

Police say officers were briefed about Belenky Wednesday morning and were told to alert investigators from the major crimes unit if they come across him.

"What happened today is a bit of a briefing note to field officers. Basically, the point is that given the high profile of what's happened, the allegations in Omaha, we did a security risk assessment," says Kevin Brookwell with CPS.

Brookwell is referring to a double murder investigation in Omaha, Nebraska.

Belenky once worked there, alongside Dr. William Hunter.

In 2008, Hunter's 11-year-old son, Thomas and the family housekeeper were murdered in the family's home.

Omaha police, who came to Calgary more than a year ago, acknowledge they've known about Michael Belenky throughout the investigation.

He has not been named a suspect, but it's one of the leads cold case investigators have been following.

Belenky has no warrants and is not accused of any crime.

In an interview in an Omaha newspaper, Dr. Hunter says he had a cordial relationship with Belenky, they always got along very well and he's never believed Belenky was involved in any way.
