Carver became eligible for parole in 2018 but declined to seek it because he did not want to accept responsibility for a crime he says he did not commit. In 2020, citing a history of cardiovascular disease, skin cancer, and depression, along with using a wheelchair due to dizziness, vertigo, tremors and seizures he suffered following brain surgery, as well as being diagnosed with prostate cancer (which he was refusing treatment for), Carver sought a medical parole on the grounds that he was "highly likely" to become incapacitated if he contracted
COVID-19. His petition was denied by the state commissioner of corrections and the decision was upheld by a Superior Court judge. In 2023, the
Massachusetts Supreme Judicial Court upheld the corrections commissioner's decision. In 2022, attorneys from the state public defender's office and
Boston College Law School's Innocence Program petitioned for a new trial, arguing that modern fire science shows there was no evidence the fire was started with gasoline and that it might have been accidental. In 2024, Carver was granted a retrial and released on personal recognizance. The Essex County district attorney's office appealed the ruling. In February 2025, Carver's conviction was formally overturned, with the judge citing advances in eyewitness science and fire investigation techniques as the most compelling factors in such a ruling. It remains unclear if the Essex County district attorney's office is still pursuing appeals, seeking to re-try Carver, or investigating other possible causes of the fire. ==Effect on building codes==
