A trial began Monday for the last of four men charged in a fatal robbery in Portland in 2022.

Jonathan Geisinger, 48, has been charged in Cumberland County with one count of felony murder and one count of robbery. He is accused of having a role in the death of Derald “Darry” Coffin, who was shot and killed on Woodford Street a little after 1 a.m. on April 26, 2022.

Coffin and his friend, Annabelle Hartnett, were shot after Coffin was attacked by a group of men, including Anthony Osborne, who was an acquaintance.

Hartnett survived her injuries and is expected to testify this week. She previously testified against Damion Butterfield, who pleaded guilty in 2023 to intentional or knowing murder in connection with Coffin’s death. Butterfield did so after a nearly weeklong trial, just after a jury reached its verdict but before sharing its decision.

Osborne pleaded guilty in January 2024 to robbery, and prosecutors have said he was the one who set up the robbery. Thomas MacDonald pleaded guilty that April to one count of hindering apprehension, admitting he hid the firearm after the shooting, and is also scheduled to testify.

Geisinger pleaded not guilty in July 2022 and has spent the past four years in jail. He rejected a plea offer from the state in 2024 that would have entailed 12 years in prison, and, last summer, requested more time for trial.

Coffin’s family has attended nearly every related court hearing and packed the gallery Monday morning for the first day of the trial. They told a reporter two years ago they were frustrated by court delays and cancellations that have made it hard to heal from what happened.

Geisinger and MacDonald were childhood friends and briefly worked together as painters in 2021, according to Geisinger’s defense attorney Jon Gale. Osborne had grown up in the same neighborhood, but Gale said that was his client’s only connection to the group.

Prosecutors argued on Monday that Geisinger shared a role in setting up the robbery, while Osborne was with Coffin and Hartnett earlier that evening. Prosecutors have said they believe Osborne was calling and texting their whereabouts to Geisinger.

According to the prosecution, Butterfield shot Coffin and Hartnett using Geisinger’s gun. Gale said on Monday that Geisinger got the gun less than a month earlier from MacDonald, who purchased it.

“Mr. Geisinger put into motion the tragedy that occurred that night,” Assistant Attorney General Leanne Robbin said in court.

Gale argued that Geisinger is charged with a very specific kind of crime — felony murder — and that, in order to find his client guilty, the jury would have to believe he had more of an active role in what happened.

Butterfield appeared to shoot at Coffin and Hartnett “without provocation,” Gale said, citing testimony from Hartnett and others during Butterfield’s trial in 2023.

“Jonathan Geisinger didn’t plan a robbery,” Gale said. “He didn’t direct anyone.”
