ORIGINAL 4:20 p.m.

Two teens charged with first-degree murder in the death of a Calgary police officer have appeared in court.

Calgary police say 17-year-old Al-Azan Shah Muhammad and 19-year-old Amir Abdulrahman will remain in custody until their bail hearing on Monday.

The teens turned themselves in on Friday afternoon, less than 24 hours after Sgt. Andrew Harnett was killed during a traffic stop.

Police have said Harnett was struck and dragged by an SUV he pulled over just before 11 p.m. on New Year’s Eve.

They say the investigation is ongoing, and officers are grateful for an outpouring of support from the public.

The police service notes that those wishing to express their grief and solidarity can participate in a “blue campaign” by tying blue ribbons on homes and throughout communities, or displaying blue porchlights.

And those who want to send condolences to Harnett’s family can email.

Harnett worked as a military police officer at the Vernon cadet camp in 2007 and 2008. He’s been remembered as a “great guy” who went out of his way to work with young cadets.
