Adnan Syed, who appeared in the podcast 'Serial,' will be released from prison.

Adnan Syed's conviction was overturned by a court on Monday after his murder case was covered on the true-crime podcast "Serial," and he was ordered out from jail.

Syed was 17 years old and in high school the last time he was free. His chains were removed in the courtroom to cheers.

Judge Melissa M. Phinn made the decision after prosecutors told the court they had lost faith in Syed's conviction, citing a nearly year-long investigation that uncovered new information about "the possible involvement of two alternative suspects" and violations in the government's turning over evidence to the defense.

Syed was arrested in late February 1999 for the murder of his ex-girlfriend, Hae Min Lee. He had long attempted to have his conviction overturned and a new trial ordered, but had been met with hostility from prosecutors. The Baltimore City State's Attorney's Office then filed a motion in circuit court on Wednesday, requesting that the conviction be overturned and Syed be released while its investigation continues.

Young Lee, Hae Min Lee's brother, stated during a Monday hearing that the prosecution' move to dismiss the conviction left him feeling "betrayed."

"That's incredibly difficult for me to swallow, especially for my mother," he admitted.

"I'm not against inquiry or anything of that nature," Young Lee said, adding that "knowing that there may be someone out there free for killing my sister - it's terrible."

"I implore you to make the correct decision," he continued.

Syed's case was included on the first season of "Serial," which aired in 2014. Sarah Koenig, the show's host, recounted the circumstances leading up to Lee's death, which was discovered in Baltimore's Leakin Park. Investigators decided that she died as a result of strangling. Syed was found guilty of murder in 2000 and sentenced to life in prison.
