In the five years after Terry Hedgepeth was diagnosed as HIV-positive in 2000, he felt like a man with nothing to live for. Hedgepeth, according to court filings, grew depressed, lost his job and had suicidal thoughts. He used drugs and engaged in other risky behavior.

Only he wasn’t HIV-positive. Due to a human error, according to court documents, his results form was incorrectly filled out. He sued the Whitman-Walker Clinic for medical malpractice in 2005 in District of Columbia Superior Court.
