Mark Woodworth

Mark Woodworth is an American man from Livingston County, Missouri, who was convicted twice for a 1990 home invasion murder of his family's farming partners, the Robertsons. A tragic incident that occurred when he was 16 years old. Woodworth spent twenty years in prison for the crime he did not do, but was finally freed and exonerated, after the bizarrely handled ballistic evidence used against him was ruled to be so egregiously tainted, that it was barred from being used in a court of law. The court also barred the Missouri Attorney General's office from prosecuting Woodworth a third time. When a special prosecutor was assigned who dropped all charges. Woodworth is listed in the National Registry of exonerations.

His case was featured in episode: "Severed Ties - On the Case with Paula Zahn". As well as dozens of news articles following an alternate suspect, letters withheld from defense, and the strange twist of evidence removed in a surgery that was given to a private investigator who took it to England.
