June 21: Her day in court

Williams said the hearing was running about 10 minutes late when an attorney from the U.S. Justice Department approached him.

The attorney wanted to talk about releasing Darwin to his mother. The two stepped out.

The attorney for the Justice Department offered to return Darwin in a couple days, Williams said.

Williams said he told the attorney, "If you can do it in a couple days, do it today."

An agreement was brokered. They went back into the courtroom.

Williams told Mejia-Mejia: You're getting your son back today.

The translator changed the words to Spanish.

"She started crying...and then she cried a lot," Williams said.

District Court Judge Paul Friedman took the bench and listened to the attorneys' agreement.

Williams said he told the attorneys he wanted a status report by Friday to be sure the government had reunited Mejia-Mejia with her 7-year-old son.

Officials with the U.S. Department of Justice did not immediately return a request for comment.

Finding a flight
They left the courtroom and went straight to a nearby Starbucks where they started looking for flights.

Nothing would get Darwin to D.C. and to his mom that same day.

They found a Southwest flight that would leave Phoenix a little after 6 p.m. and get in at 1:30 a.m.

But Williams said they continued to argue with officials with the Office of Refugee Resettlement and Southwest Key, the company that operates the shelter in Phoenix where Darwin was taken after he was separated from his mother.

Officials wanted Mejia-Mejia's fingerprints. That request came after wanting birth certificates and countless copies of other documents that most migrants don't have.

No, the government arrested her, you have her fingerprints, Donovan said.

Put Darwin on the Southwest flight, he said. No more excuses.

They tracked the plane. The flight was delayed. But the boy was on the plane — his first flight ever.

From the runway, the caseworker sent photos of her boy.

In one photo, Darwin is peeking out the window.

In another, he rests his head against the window, waiting.

A few hours later, the plane was on the ground, and Mejia-Mejia was waiting at the gate, a green-and-white blanket around her shoulders. Her attorney and others stood nearby, video cameras rolling.

After 2 a.m., Darwin stepped into the terminal. His eyes said he was unsure what was happening.

Mejia-Mejia set him in a waiting room chair, and wrapped the blanket around her son.

Then she wrapped her arms around him and sobbed.

“Why did they do this to us?" she said to him in Spanish. "Why did they separate us?”

"I love you son, the only one I have," she said. "Thank God you're with me, my love."
