Grand Rapids — Jurors said Friday they have reached a verdict on some counts in the case against four men accused of plotting to kidnap and hurt Michigan Gov. Gretchen Whitmer but are locked on others.

Chief U.S. District Judge Robert Jonker announced the development just before 11 a.m. Friday and encouraged jurors in federal court in downtown Grand Rapids to keep deliberating in hopes of reaching a unanimous verdict.

“It is not unusual to come back somewhere along the line of deliberations and say ‘we tried, but couldn’t get there,'” the judge said. “At least not on everything.”

The trial has lasted 20 days, including 13 days of testimony and approximately 35 hours of jury deliberations spanning five days. Jurors — six men, six women, all white — heard hours of closing arguments and instructions Friday after testimony and a multimedia case from the government.

Jonker likened the situation to the game show “Who Wants to be a Millionaire,” and the famous catchphrase “Is that your final answer?”

“Before that’s the final answer, I would like you to go back and make another effort to see if you can come to an agreement on issues you are stuck on as a group,” the judge told jurors.

The trial has coincided with jurors in federal court in Washington, D.C., hearing the first cases involving people charged in the Jan. 6 riot at the U.S. Capitol. Together, the trials provide the first tests of federal laws being used to punish extremist behavior that erupted nationally in 2020 and 2021 around the presidential election and pandemic.

In Grand Rapids, four men are on trial, charged with kidnapping conspiracy, a felony punishable by up to life in prison. They are: Adam Fox, 38, of Potterville, Barry Croft, 46, of Delaware; Lake Orion resident Daniel Harris, 24, and Brandon Caserta, 33, of Canton Township. Three are facing multiple charges, including conspiracy to use a weapon of mass destruction.

Jurors entered the courtroom before 11 a.m. Friday without looking at the four defendants across from them. Some jurors sighed after hearing they would be sent back for more deliberations.
