Stephens had pulled into a McDonald's drive-thru, and an employee immediately recognized him.
A five-state manhunt was launched to find Stephens after the children's mental health worker vowed to "keep killing until they (police) catch me". DuCharme said the attendant then called state police.
Stephens, accused of randomly killing a 74-year-old retiree in Cleveland on Sunday and sharing video of the murder on Facebook, died Tuesday of a self-inflicted gunshot wound in Erie, Pennsylvania.
According to the Daily Mail, DuCharme said another McDonald's employee reported Stephens asked them for directions to the interstate.
After the slaying of Godwin, Lane was placed in protective care while authorities launched a nationwide hunt for Stephens over the course of several days.

District Judge Sean Cox on Friday accepted a plea agreement reached in January between the automaker and the federal government. In his ruling on Friday, Judge Cox said, "I can't believe the VW is in this situation that it finds itself in today".
Lane said it has been hard watching her name dominate social media, where her connection to the killer became a topic of discussion over the weekend.
Stephens' run from the law came to an end when he stopped at a McDonald's in the Pennsylvania county.
Stephens broadcast the fatal shooting of another man live on Facebook on Sunday, April 16, 2017.
Stephens filmed and then posted the video of the attack to Facebook, but was found dead in his vehicle on Tuesday.
Facebook chief executive Mark Zuckerberg said: "Our hearts go out to the family and friends of Robert Godwin Sr". The family does not blame Lane for what happened.
In interviews before Stephens' death, Godwin's relatives said they forgave his killer.
Until the investigation is complete, Williams said, "we won't actually know where he was and what he was doing".
"They don't make men like him anymore", Debbie Godwin said.
