Closing arguments end in Guillermin manslaughter trial; jury deliberations next

Chief prosecutor Chester Hinds and defense attorney Brien Sers Nicholas made their final appeals to jurors last Oct. 21, as the manslaughter trial of Jeremy Guillermin moved closer to jury deliberations in Superior Court.

Hinds, in a 13-minute closing argument, maintained that Guillermin's fatal punch of Alvin Remamba outside Relox Bar in Garapan on Nov. 16, 2025, was unnecessary and not an act of self-defense.

Sers Nicholas, in a much longer 32-minute closing statement, countered that his client acted in self-defense after being provoked by Remamba and accused the prosecution and police of conducting a reckless investigation.

Hinds relied heavily on surveillance footage that he said showed Remamba trying to walk away, return inside the bar and seek police assistance before Guillermin punched him, causing him to fall backward and strike his head on the concrete. Remamba died four days later.

Sers Nicholas challenged that interpretation, arguing that Remamba was looking for a fight and that Guillermin, who weighed about 130 lbs, was defending himself.

The defense attorney also questioned how police and emergency personnel handled Remamba after he collapsed, suggesting shortcomings in the investigation.

He reminded jurors that Guillermin, who did not testify, was presumed innocent and that prosecutors must prove their case beyond a reasonable doubt.

In his six-minute rebuttal, Hinds rejected the defense's portrayal of Remamba as a bully, saying the videos showed otherwise. He also cited Guillermin's apology letter, arguing that the defendant knew his actions were wrong.

Hinds reminded jurors that Remamba was a 30-year-old father, son, and brother whose life ended following the confrontation.

Remamba's mother, Veronica Taitano, and older sister, Arvie, were visibly emotional as the attorneys revisited the fatal incident.

Guillermin, meanwhile, remained seated beside his attorney as both sides made their final appeals.

The prosecution sought convictions for voluntary manslaughter, aggravated assault and battery, and obstruction of justice. The defense asked jurors to acquit Guillermin of all charges.

Presiding Judge Joseph N. Camacho adjourned Wednesday's proceedings shortly after 5pm. Jury instructions will begin Thursday, Oct. 22, at 9:15am, after which jurors are expected to begin deliberations.

Earlier Wednesday, Commonwealth Healthcare Corp. pathologist and laboratory director Dr. Philip Dauterman testified that Remamba died from a traumatic brain injury involving a six-inch skull fracture and extensive bleeding.

Dauterman said the autopsy revealed approximately seven ounces of blood beneath Remamba's scalp and blood clots that compressed his brain.

He classified the manner of death as homicide, a medical finding that does not by itself establish criminal guilt.

Autopsy photographs showing Remamba's injuries were displayed to jurors. Taitano and Arvie appeared distressed as the images of their loved one's injuries were shown, with the former momentarily leaving the courtroom.

Sers Nicholas objected, describing the photographs as gruesome, prejudicial, and unnecessary because Dauterman had already explained his findings. Camacho allowed the photographs, finding them relevant to the injuries.

Under cross-examination, Dauterman acknowledged that he was not board-certified in forensic pathology, but maintained that his qualifications in anatomical and clinical pathology allowed him to perform autopsies and determine causes of death.

Sers Nicholas also questioned him about preliminary and final autopsy reports and Remamba's intoxication.

Dauterman acknowledged that Remamba had a blood alcohol concentration of approximately 0.283 when admitted to the hospital but said intoxication was not the cause of death.

Earlier, Camacho allowed Dauterman to testify within his recognized expertise in clinical pathology while limiting opinions outside that field.

Sers Nicholas also sought dismissal of the charges for insufficient evidence and challenged proposed jury instructions on lesser-included offenses.

Wearing beige after appearing in red and pink attire on previous trial days, the defense attorney continued his pointed questioning of Dauterman before making his final appeal to jurors.

The trial opened Monday with testimony from police officers and surveillance footage of the confrontation.

Tuesday's proceedings featured emergency physician Dr. Gregory DiCamillo, who testified about Remamba's severe head injuries, and Arvie, who described her brother's hospitalization and the family's decision to withdraw life support.

Arvie later told reporters that the family was seeking justice, not monetary compensation.

Guillermin, a Palauan national who was in Saipan for Aircraft Rescue and Firefighting training, also faces an obstruction charge stemming from allegations that he escaped from a police vehicle while handcuffed.

Jurors will determine whether prosecutors have proven the charges beyond a reasonable doubt, including whether Guillermin acted in self-defense.
