Not much in the way of details.
I wonder if it is going to turn out to have been the result of an argument rather than a mistake.
NY police officer shoots, kills his 37-year-old son, mistaking him for intruder, troopers say
Horrible thing to happen, can not imagine what he must be feeling. Have to ask, if son was 37 he is no spring chicken and obviously no rookie, should have better training and control of his weapon to verify the target before shooting.
That's why I think it might not have been as he said. Just seems too incredible for the circumstances.
