In 1987, Guy "Gordy" Marsh was released from prison after serving 14 years in prison for a murder he did not commit and was set up for by a detective.

On June 28th, 1971, Charles Erdman was murdered inside a Glen Burnie, Maryland 7-Eleven on Crain Highway after attempting to stop a robbery that was in progress by two masked men. The main witness against Marsh at trial was Linda Packech, a heroin addict with a lengthy criminal record. She claimed to have seen Marsh come out of the 7-Eleven and raise his mask. Her testimony was the primary evidence used to convict Marsh. He was sentenced to life-plus-ten years in prison.

In 1987 though, Packech admitted that she had lied during the trial. She eventually told both a reporter and the prosecutor that she had been pressured to identify Marsh by a Anne Arundel County police detective who was convinced he was guilty, but was unable to find any evidence implicating Marsh after an 18-month investigation. In actuality, Packech was in jail on shoplifting charges at the time of the crime and could not have been present at the murder scene. Marsh’s original conviction was overturned and prosecutor’s decided not to retry him, making him a free man. Packech was eventually convicted of perjury for her testimony during Marsh’s trial.  

In 2005, Marsh (along with several other exonerees) attended the Mid-Atlantic Innocence Project’s National Innocence Network Conference, where experts and advocates convened to discuss recent developments in the fight to exonerate the wrongfully convicted.

Because technically, prosecutors never acknowledged Marsh's absolute innocence, he has been unable to receive a full pardon and has thus been ineligible for compensation, despite the misconduct that went into his wrongful conviction. Marsh has spent much of the past twenty years as a truck driver in Maryland.
