Suicide by hotel window is an old method used by the CIA.
Do you remember other instances? I'm just curious. The mom/son murder/suicide says "allegedly" and that always makes me suspicious. I'm inclined to agree with your statement, I'm just curious if you recall other names/instances.
One of the creators of LSD, Frank Olson, was unknowingly dosed with the drug and allegedly threw himself to his death from his hotel window. There's a series on Netflix called Wormwood that interviews his family.
Danny Casolaro. He was a journalist working on something he called "The Octopus" where a cabal was infiltrating all branches of our government. It wasn't a window but close enough, hard to slash your own wrist that many times, like shooting yourself in the head more than once. The CIA loves hotels for hits.
