Lawyers for Adnan Syed, whose murder case was spotlighted on the popular “Serial” podcast in 2014, said on Monday that they had filed a motion in a Maryland court asking that Mr. Syed be released on bail.

If the motion is granted, Mr. Syed, 35, who was convicted in 2000 of murdering his former girlfriend Hae Min Lee, will be free for the first time in 17 years.

The motion was filed by Mr. Syed’s lawyer, C. Justin Brown, more than three months after Judge Martin P. Welch of the Baltimore City Circuit Court granted Mr. Syed a new trial.

“Syed has now served more than 17 years in prison based on an unconstitutional conviction for a crime he did not commit,” the filing said. “He has no history of violence other than the state’s allegations in this case, and if released, he would pose no danger to the community.”
