I believe that "news" is fake.
great story.. buuutttt... How? How would anyone know the traffic lights were faulty?
my guess is, the guy crossing the bridge simply didn't get across before her light turned green.
Why would she not wait for him to completely cross the bridge?
The coroner doesn't blame deaths on traffic lights. cops might.. fake news might.. but coroners don't.
Coroners determine cause of death based on physical evidence on or in the body and or remains of such.
So, I say it's bullshit.
