TUCSON — Jurors in the high-profile felony trial against Scott Warren — a humanitarian-aid volunteer charged with harboring two undocumented immigrants in southwestern Arizona — were unable to reach a verdict, prompting the judge to declare a mistrial in the case.

U.S. District Judge Raner C. Collins brought the 12-person jury into the Tucson federal courtroom on the afternoon of June 11, after they indicated for a second time that they were deadlocked on all three charges Warren faced.

The judge dismissed the jury after each member told him that additional time deliberating would not result in a verdict.

Collins scheduled a status conference on the trial for July 2, when prosecutors with the U.S. Attorney's Office in Arizona will announce whether to try Warren again before another jury.

Prosecutors declined to comment after the judge dismissed the jury. In a statement, the U.S. Attorney's Office in Arizona said they would make the decision about a retrial before the July 2 hearing.

Warren, 36, a volunteer with the group No More Deaths, faced up to 20 years in federal prison if convicted.

He's accused of conspiring to transport two undocumented immigrants, Kristian Perez-Villanueva and Jose Arnaldo Sacaria-Goday, and of harboring them for several days in January 2018 in Ajo, Arizona.

Speaking to reporters outside the federal courthouse, Warren acknowledged that he'd be back in court in a month's time to learn if the legal case against him would continue.

But he thanked his supporters who filled the courthouse to capacity on each of the seven days of testimony.

"But the other men arrested with me that day, Jose Sacaria-Goday and Kristian Perez-Villanueva, have not received the outpouring of support that I have," Warren said. "I do not know how they are doing now. But I desperately hope that they are safe."

Warren said that the need to provide humanitarian aid to migrants crossing the desert along the U.S.-Mexico border still is "as necessary" as ever.

He pointed out that since his arrest on Jan. 17, 2018, the remains of 88 migrants were recovered from the Ajo corridor, a remote and notoriously rugged desert wilderness in southwestern Arizona.

Greg Kuykendall, the lead attorney in his defense team, praised volunteers, such as Warren, for using their time and resources to help migrants in need.

He declined to answer questions about the possibility of a retrial.

"The government put on its best case, with the full force and countless resources, and 12 jurors could not agree with that case," Kuykendall said. "We remain devoted today in our commitment to defend Scott's lifelong devotion to providing humanitarian aid."

Volunteers say border humanitarian work will continue

The hung jury in Warren's felony trial follows the convictions of several other No More Deaths volunteers for carrying out humanitarian aid duties along protected wilderness areas along the Arizona border.

In January, a federal judge in Tucson convicted four volunteers of misdemeanors for entering a wildlife refuge without a permit and dropping off food and water for migrants. He sentenced them to 15 months probation, ordered them to pay a fine of $150, and banned them from the refuge.

The following month, four other No More Deaths volunteers pleaded guilty to a civil infraction of entering a wildlife refuge without a permit, and agreed to pay $280 in fines.

Warren is also awaiting the outcome of a separate misdemeanor case brought against him for entering protected wilderness areas without a permit.

Page Corich-Kleim, a longtime volunteer with No More Deaths, said despite these results, their work in providing humanitarian aid will continue along southwestern Arizona.

"This evening, we have a group of volunteers driving out to Ajo to put water out," she said. "So throughout this whole trial, we haven't stopped doing our work and we're not going to stop doing our work."

The jury began deliberations midday on Friday, after attorneys presented their closing arguments in Tucson federal court. But after nearly 15 hours of deliberations, they were unable to reach consensus on the three felony counts against Warren.

The jurors first notified Collins late Monday afternoon that they were unable to reach a verdict in the case. But the judge asked them to try once again on Tuesday morning.

But after deadlocking once again on Tuesday morning, Collins thanked them and dismissed them from jury duty.

The jurors left the courthouse without speaking to the media.

Prosecutors said Warren conspired to harbor migrants

During the trial, prosecutors with the U.S. Attorney's Office in Arizona argued that the two migrants were in good health and did not need medical care when they showed up to a building known as "the Barn" on Jan. 14, 2018.

The prosecutors argued that Warren had conspired with Irineo Mujica, a migrants-rights activist who runs a shelter in nearby Sonoyta, Mexico, to take in the two migrants and shield them from Border Patrol. They also alleged that the humanitarian aid was used as a "cover" to help them further their journey illegally into the United States.

Agents arrested Warren, as well as Perez-Villanueva and Sacaria-Goday, during a Jan. 17, 2018, raid of the Barn, after they had set up surveillance of the area.

Defense attorneys for Warren said he had no idea that the two men would be at the Barn when he arrived, and that he had followed the protocols No More Deaths had established to provide a medical assessment, as well as food, water, shelter and orientation to the two migrants.

Warren's intent was not to break the law, but rather to provide lifesaving aid, his attorneys said.
