Loud popping noise from left rear wheel followed by loud sustained squeek on 1998 Volvo S70

As I drove the car from parked position a few car lengths a loud popping noise from left rear wheel followed by loud sustained squeek occurred and I stopped immediately. A few more tries produced the same thing. I parked the car for towing to shop. The popping noise sound like metal gripping metal being yanked away by great force.

Suspect a park brake locking and not releasing or brake problem.
I think ron is right, but also check the upper strut mount, they break and cause all kinds of ruckus from the rear of the car.
