No, they have physical evidence, audio evidence which probably means camera or video doorbell and the kid died on the front porch of someone else’s house. Seems like the story told itself. The simple explanation is he tried breaking into the wrong house thinking it was his own.
Not saying he deserved to die over his mistake, it’s tragic and sad that the situation occurred.
Editing to add this from the article:
“evidence gathered at the scene, review of surveillance video that captures moments before the shooting, audio evidence, and witness statements.”
