Prosecution's Case and Verdict

In the fall of 2021, a young couple in Cobb County, Georgia thought they’d found their dream home. An upscale subdivision. A quiet street. A perfect place to raise their two year old son.

What they could not have known was that the house came with an unspoken history. A neighbor who had already crossed the line. A fear that had driven the previous owners to leave. And a threat that did not disappear when the “For Sale” sign went up.
