Former U.S. Navy Hospital Corpsman Collin J. Potter, 31, who earlier this year pleaded guilty to second-degree murder while armed for the Jan. 6, 2019, stabbing death of gay D.C. resident Vongell Lugo, was sentenced Sept. 15 by a D.C. Superior Court judge to 16 years in prison and five years of supervised probation upon his release.  

The sentencing took place at a hearing in which Assistant United States Attorney Peter V. Roman, the lead prosecutor in the case, described in gruesome detail how Potter stabbed Lugo 42 times inside Lugo’s Northwest D.C. apartment shortly after the two met at a D.C. bar and Potter accepted Lugo’s invitation to come to the apartment.

Superior Court Judge Marisa Demeo handed down her sentence after listening to testimony by Lugo’s mother, brother, and sister, and seven of Lugo’s friends, who presented highly emotional victim impact statements describing Lugo as a beloved figure whose brutal murder had a devastating impact on their lives.

Nearly all of the 10 who spoke – eight in the courtroom and two through a live video hookup – urged the judge to hand down a far greater prison term than the 14 to 16-year sentence that prosecutors with the Office of the U.S. Attorney for D.C. offered and Potter accepted in exchange for pleading guilty as part of a plea bargain deal. The plea arrangement made it clear that the judge would make the final decision on what the sentence should be.

Under D.C. criminal law, judges have the discretion to hand down a sentence of up to life in prison for a second-degree murder conviction.

Many of the family members and friends wept as they described Lugo, 36, as a loving, caring person who enriched their lives and who was taken from them by Potter in an unimaginable act of violence.

The sentencing took place a little over seven months after Potter, who was 26 at the time of the murder, pleaded guilty to the charge of second-degree murder while armed and prosecutors dropped their original charge of first-degree murder while armed and other related charges as part of the plea bargain deal.

Court records show that at the request of prosecutors, a D.C. Superior Court grand jury on Aug. 20, 2019, indicted Potter on five counts related to the murder, including two counts of first-degree felony murder while armed, felony murder while armed with aggravating circumstance, and kidnapping.

The U.S. Attorney’s Office has declined to disclose why prosecutors offered the plea deal that included dropping those charges and allowing Potter to plead guilty to second-degree murder rather than bringing Potter to trial on the first-degree murder and other charges.  

Attorneys familiar with this type of case have said prosecutors usually offer a plea deal when they are uncertain whether they can convince a jury to find someone guilty beyond a reasonable doubt at a trial.

At the Sept. 15 sentencing hearing, Potter’s defense attorney, Matthew Davies of the D.C. Public Defender Service, told the judge one reason why the plea offer made sense was it avoided a trial in which Potter would likely have used the defense of insanity or severe mental health problems, that Davies said his client is currently grappling with.

Davies pointed to information submitted by the defense that Potter has a history of trauma brought about by being sexually abused as a child. He said Potter also has an alcohol abuse problem and related mental health issues, and those factors led to the stabbing incident that took the life of Lugo.

He asked the judge to hand down a sentence of 14 years of incarceration, saying that would adequately serve the cause of justice for this case.

The subject of Potter’s mental health also surfaced in a 10-page sentencing memorandum that Roman filed in court two days before the sentencing, and which Roman summarized at the hearing, including the recommendation of a sentence of 16 years of incarceration.

The sentencing memo begins by describing Lugo as an “openly gay man who was born and raised in Trinidad & Tobago before emigrating to the United States with his family several years ago.” One of Lugo’s friends told the Washington Blade that Lugo had been working as an associate manager for a company that provides language translation services.

The sentencing memo says police arrived at Lugo’s apartment about 4 a.m. on Jan 6, 2019, when two neighbors called 911 after hearing Lugo screaming for help through the walls of their adjoining apartments.

It says police arrived shortly after Potter, who was fully nude and covered in Lugo’s blood, had dragged Lugo’s nude body outside the apartment door into the apartment building hallway.

“After the police arrived, the defendant made several statements,” the sentencing memo says. “He repeatedly referred to Mr. Lugo as his girlfriend and as a female and stated that Mr. Lugo’s injuries were self-inflicted,” the memo continues. “The defendant then banged his own head against the wall and started screaming obscenities and that he did not want to live,” it says.

Several of the close to 20 friends and family members of Lugo who were sitting in the courtroom as prosecutor Roman presented these details were crying.

Defense attorney Davies told the judge that he informed Potter that he had a strong defense based on mental health issues if the case went to trial. But Davies said Potter expressed strong opposition to going to trial and subjecting Lugo’s family to additional trauma.

Court documents show Potter was arrested at the scene and has been held in jail since that time as the case dragged on for more than four years since the January 2019 murder.  

Court records also show that Lugo and Potter met at the Black Whiskey, a bar on 14th Street, N.W.  where Lugo was a regular customer. Although some of Lugo’s family members and friends who spoke at the sentencing hearing said they considered the murder a hate crime, court records show police and prosecutors did not list the case as a hate crime.

“He was a beautiful gay man, and everyone loved him,” Hannah Donnelly, one of Lugo’s friends and co-workers said in presenting her victim’s impact presentation in the courtroom.

Another friend said in her impact statement that Lugo invited her to join him to watch D.C.’s Capital Pride parade. She and nearly all the others who presented their impact statements at the hearing were not gay or lesbian themselves but said Lugo was beloved because he always did all he could to help them and support them in their everyday lives.

“He was like a brother to me,” said Gregory Porter, one of Lugo’s friends who, along with his wife, presented their victim impact statements in the courtroom. “There was never a thought that he would no longer be a part of our life,” Porter told the judge. “We ask for equal justice. We ask the court to invoke the maximum possible sentence,” he said.

Victoria Lugo, Lugo’s mother, was the first of the family members and friends to deliver her victim’s impact statement. Looking directly at Potter, she told him there was nothing her son could have done to him to justify what Potter did.

“You have taken my child from me, Mr. Potter,” she said while crying. “My heart hurts,” she continued. “No mother should have to go through this.”

Potter, who was dressed in an orange prison jumpsuit, accepted Judge Demeo’s invitation to speak before she handed down her sentence.

“I’d like to say I am truly very sorry,” Potter told the judge. “I accept the consequences of my action,” he said. “I feel I will spend the rest of my life having a positive impact on other people’s lives to make up for what I have done,” he said.

After listening to Potter, the presentations by Lugo’s family members and friends and hearing remarks from prosecutor Roman and defense attorney Davies, Judge Demeo said she would accept the plea agreement. She said the circumstances surrounding the case, including what she called the “brutal nature of the crime,” warranted that she issue a sentence representing the upper end of the plea agreement of 16 years’ incarceration and five years of supervised release.

She said she would order that the facility where Potter is incarcerated will provide him with mental health treatment.  

“There is no doubt that this was a horrific crime,” she said. “Vongell Lugo was shown by witnesses to be a wonderful soul,” she added.
