She also defended Ryan Ferguson, who spent 10 years in prison after being wrongfully convicted of a Missouri Murder.

In 1994, Zellner successfully had a wrongfully convicted Joseph Burrows released from death row. Gayle Potter claimed that Burrows had killed a 88-year-old farmer where Potter had admitted to forging a check from the murdered. Although numerous witnesses swore they saw Burrows miles away from the murder scene, Burrows was convicted. Zellner pursued the case and won a new hearing where Potter confessed for the false claim. Burrows was released in 1994 and filed for a civil suit against the police where he won $100,000 (a small amount compared to what comparable cases had been awarded).
She has also represented Ryan Ferguson. A personal trainer, Ferguson was arrested in 2004 for the 2001 murder of Columbia Tribune sports editor Kent Heitholt and nearly spent 10 years in jail. On the night of the murder, Charles Erickson had spent partying with Ferguson and could not recall the evening.

Zellner went on to investigate the original court filings and identified numerous inconsistencies. There was evidence being withheld in the original trial, the key witnesses had lied during testimonies from pressure from prosecutors, and the story from a co-worker of the murdered had material inconsistencies. During a new hearing, Zellner questioned the co-worker to the point where the co-worker confessed to being with the murder victim at the time of the crime.

Avery wrongfully served 18 years before being exonerated after DNA testing. Avery filed for a $36m lawsuit in 2003 against the police, but was arrested for the murder of another woman who was killed in 2005. Avery’s nephew Brendan Dassey confessed to helping Avery kill the victim under interrogation by police. Although Dassey tried to recall his statement, it was not accepted.
