“Crushed by barbell” is easiest homicide to fake as “accident”.
Few weight lifters bench press without safety stops in place.
When I’ve done this in decades past, I’d roll the bar down my chest to my waist.
It’s NEVER landed on my neck.
Years ago I lifted weights. I would lift lighter weights without a spotter. Anytime I lifted weights that were near my maximum ability, I always had a spotter. On occasion I could not lift the weight and it would come to rest on my chest or the spotter helped me put it on the stop. If this man lifted weights on a regular basis he knew what was safe and not safe. This reeks of murder.
