·2 min read

A preliminary hearing is set Nov. 23 in Lloydminster Provincial Court for a man accused of a 2019 murder on Onion Lake Cree Nation.

Marvin Stanley, 28, is charged with second-degree murder in connection to the death of Conrad Mooswa, 32, of Makwa Sahgaiehcan First Nation.

According to Onion Lake RCMP, they got a call in the early morning hours of Oct. 23, 2019, about a disturbance at a residence on Onion Lake First Nation. When police and EMS arrived they found Mooswa unresponsive and in medical distress. EMS declared him deceased at the scene and police secured the residence.

Mooswa’s murder in December 2019, along with the murders of Braden Bull and Alfred Sparvier in January 2020, led Onion Lake Cree Nation to declare a state of emergency Jan. 24, 2020. The body of Bull, 32, of Little Pine First Nation was found on Onion Lake Cree Nation Jan. 21, 2020. Sparvier’s body was found Jan. 1, 2020, along a road in the R.M. of Frenchman Butte, which borders Onion Lake Cree Nation.

“The Nation has now experienced three deaths directly related to drugs and gang activity within the last two months, along with numerous high speed chases and violent crimes,” Onion Lake Cree Nation said in their January 2020 media release when declaring a state of emergency.

Vega Bear, 24, and Branden Dillon, 26, are charged with second-degree murder in connection to the death of Bull. Shari Heathen, 27, is charged with second-degree murder in connection to Sparvier’s death.

The RCMP Major Crime Unit South, Lloydminster Police Dog Services, Lloydminster Forensic Identification Section, Edmonton Bloodstain Pattern Analysis Section and Onion Lake RCMP Detachment members were involved in the investigation into Mooswa’s murder.
