The Baltimore City state’s attorney announced on Tuesday that his office would withdraw a motion to vacate the conviction against Adnan Syed, who has spent decades in prison while fighting charges that he had killed his high school girlfriend, Hae Min Lee.

Mr. Syed’s case was chronicled in the hit podcast “Serial,” which presented new evidence and led to a swell of interest in the case. The previous Baltimore prosecutor had asked a judge to overturn the conviction in 2022, citing issues with initial evidence and other possible suspects.

Though the charges against Mr. Syed were dropped that year, his conviction was later reinstated and Maryland’s highest court ordered a redo of the hearing that freed him.

In a statement, the Baltimore City state’s attorney, Ivan J. Bates, said that his office had determined that the legal filings by the previous administration were “false and misleading.”

“We cannot adopt the falsehoods and misleading statements in the Motion to Vacate Judgment nor fail to bring them to the Court’s attention,” Mr. Bates said. He added, “I did not make this decision lightly, but it is necessary to preserve the credibility of our office and maintain public trust in the justice system.”

This is a developing story.
