Thinking about Walmart's attitude towards both its bottom line and its workforce, I wonder whether Walmart is withholding CCTV footage from Halifax police. I don't know enough about the legal procedures needed if Walmart is not cooperating. Walmart would probably be asked about accounting for all employees in the building, attendance records, disgruntled former employees, potential outside threats, and of course, who works in the bakery section. I hope there is some level of cooperation. We can only speculate here.
The Walmart is a large worksite - employee interviews and evidence collection may take a long time.
IMO, this is not a suicide. I think
@No_Stone_Unturned's scenario 2 applies.. I think Ms Kaur was placed in the oven. Perhaps this is a rejected suitor or serial harasser in the workplace. I hope the COD can be established from the remains.
