You asked us not to immediately "call BS" without good reason.
So, here are my reasons for disbelieving your story:
1) Since the object is generating its own light and cannot be a reflection due to the sun's angle and clouds, it is probably manmade. I would have originally said it was a small firework or flare until you said "crash site".
2) The object is traveling at an unreasonably high velocity if the upper lines form the trail in a decent coming towards you (green arrow in the picture below). This is because cumulous/nimbostratus clouds typically form above 2,000 ft. and the object is not falling at 90 degrees - meaning the light indicates a large object traveling at an unreasonably high velocity.
3) The light trail is illogical if the object is falling from the right at a more reasonable speed (red arrow). If it isn't the light trail, then the object must be descending end over end despite the base being larger and heavier.
So assuming this object crashed within walking distance as you suggested, it had to fall between the path of the red and yellow arrows with its trajectory aimed in your direction closest to (2). You then claim black vehicles arrived at the crash site and quarantined it. This means, they were able to project exactly where it would land and got there before someone in walking distance could (ie: not any sort of space debris).
I call BS.
It's probably a glare from a window, firework, or separate image pasted onto a base picture.
