A lawyer for a convicted killer Adnan Syed has filed a motion arguing that mobile phone data placing the man near the murder scene should not have been introduced at trial.
Syed was convicted in 2000 of killing his high school girlfriend Hae Min Lee and saw his case revived in the popular Serial podcast.
His lawyer Justin Brown said the state used mobile tower data to link Syed to Leakin Park in Baltimore, Maryland, where the woman’s body was found.
But in a note attached to the data, AT&T warned that only outgoing calls can be traced, and that “incoming calls will not be considered reliable information for location”.
Despite this note, Mr Brown argues, the state used the data to trace incoming calls.
