He claimed to have suffered from hearing voices and Electro-magnetic microwave exposure.
I experienced a situation in my old apartment.
My neighbor upstairs was using an high-powered electronic pest control device; and because of my fragile health, I had trouble sleeping and started hearing the static noise all the time. It was giving me headaches and I heard random radio voices. I just think there are some humans that are more susceptible to high powered electronic devices, especially if they already suffer from poor health. Prolonged exposure can really make someone paranoid and delusional.
Are you saying it was a psychological effect of the receiver, or are you implying she was hearing the actual voices on the radio when there was no radio? The human brain is not a transducer.
Some humans with sensitive hearing can hear radio waves but its possible if there are also metal conductors around that person or wiring that radio waves can piggy back off of. The ultrasonic pest removals carry the sound waves through electrical outlets.
My neighbor had the high powered ultrasonic pest removal, and I could feel the electrical impulses coming from the wiring in my room - through the lights, the digital clocks. It was very strange and alarming. My brain felt like it was turning to mush. My body is just really sensitive. I tried taking medication but it made my body more sensitive. I gave up and moved out as quickly as I could.
My old apartment was in NW DC, but I don't think this shooter lived there, he probably lived in Northern Virginia. But it wouldn't surprise me if one of his neighbors was using a high-powered ultrasonic pest removal. They can drive an agitated person crazy especially after prolonged exposure of several weeks. I think those electronic pest removal devices can be dangerous when exposed closely to some humans.
No...
Better explanation is schizophrenia or some type of mental illness resulting in delusions and hallucinations.
