Do you remember the name Sonia Varaschin?
She's the 42 year old Orangeville nurse killed 4 years ago tomorrow.
Police say she was brutally murdered in her home and her body was found a few days later in a wooded area.
Since then, there has been nothing.
No arrests and no suspects identified.
But fourt years after the woman was butchered, there's a new development in the case.
Police have released a short grainy video from just before 6 in the morning the day she died. Two men in a gazebo near where her vehicle was found.
Officers say the two are not suspects, but investigators would like to speak with them. At this point they are only being called possible witnesses.
Anyone who recognizes these men are asking to call police.
