West Baltimore Man Rejects 35-Year Deal in Ghost Gun Shooting at Family Home

A 53-year-old man accused of threatening to kill everyone inside a West Baltimore home before opening fire during a family argument has rejected a plea deal that would have sent him to prison for decades, setting the case on a path to trial this winter. John Harrison is charged with attempted first-degree murder and a string of related counts stemming from the confrontation, which police say ended with him allegedly retrieving a firearm and shooting at a relative who fled down the street for safety.

According to a statement of charges detailed by Baltimore Witness, Harrison argued with the victim, his wife, and three other residents before the confrontation escalated. Police say Harrison, who was visibly intoxicated during the altercation, threatened to kill everybody in the house before retrieving a gun. The victim told police, “He pulled a gun out and shot at me,” before running down a nearby street to escape.

A Baltimore Police Department officer was flagged down by the victim on the 1600 block of Division Street, according to the outlet's reporting. Officers determined that no one was struck by gunfire, but they recovered six 9mm shell casings at the scene. Police moved the residents of the home outside as the investigation unfolded, and Harrison was ultimately arrested after being ordered to surrender inside a nearby residence.

Ghost Gun Allegedly Found Under Mattress

Investigators say they recovered a gun allegedly hidden beneath Harrison's mattress, which police described as a ghost gun — an unserialized, untraceable firearm. The six 9mm shells collected at the scene reportedly matched the type of weapon found in Harrison's bedroom, per the same reporting. Harrison is prohibited from possessing a firearm due to previous convictions, including first-degree assault and other gun charges, according to police.

Maryland's Public Safety Article § 5-703, enacted under Senate Bill 387 and fully enforced since March 2023, bars the possession, sale, or transfer of unserialized firearms or unfinished frames and receivers lacking federally compliant serial numbers, according to the Maryland Department of State Police. Violations of that statute carry penalties of up to two to five years in prison and $10,000 in fines. The alleged ghost gun recovery fits into a much larger pattern across the city: between January 1 and August 1 this year, Baltimore police seized 1,189 firearms citywide, including 123 untraceable ghost guns, and made 743 gun arrests, according to the Baltimore City Mayor's Office.

The city has also gone after the supply chain behind untraceable weapons. Baltimore secured a $2 million settlement with gun retailer Hanover Armory in April over the distribution of unserialized ghost gun assembly kits, following a $1.2 million settlement with kit manufacturer Polymer80 in 2024, as Hoodline reported in its piece on the ghost gun settlement.

Plea Rejected, Trial Set for December

Harrison was charged with attempted first-degree murder, attempted second-degree murder, first-degree aggravated assault, second-degree assault, illegal possession of ammunition, wearing or carrying a loaded handgun, using a handgun in the commission of a felony, wearing or carrying a handgun, and carrying a dangerous weapon with intent to injure. During an Aug. 26 reception court hearing, prosecutors offered Harrison life in prison with all but 35 years suspended, including the first 10 years without the possibility of parole. Harrison, represented by attorney William Porter, rejected the offer.

Judge Melissa K. Copeland, who presided over the hearing, set Harrison's trial for Dec. 1, with proceedings expected to last four days. The case will move from Copeland's Felony Reception Court — the administrative hub where the Circuit Court for Baltimore City handles plea negotiations, arraignments, and trial scheduling — to Associate Judge Robert K. Taylor, who regularly presides over complex felony jury trials involving violent crime and firearm offenses, according to Baltimore Witness' background reporting on the court.

Harrison's rejection fits a pattern that has played out repeatedly in Copeland's courtroom this month. Earlier in August, a 16-year-old homicide defendant turned down a plea offering life suspending all but 60 years in a separate case Hoodline covered involving the Harman Avenue murder, and days later an East Baltimore shooting suspect turned down 30 years before being assigned an October trial date.

Sentencing Exposure Under Maryland Law

If convicted at trial, Harrison faces significant exposure under Maryland law. Attempted first-degree murder carries a potential maximum penalty of life imprisonment under Maryland Criminal Law Code § 2-205, according to legal reference site FrizWoods, which requires prosecutors to prove specific intent to kill along with premeditation and deliberation. Separately, Maryland Public Safety Article § 5-133(c) imposes a mandatory minimum of five years without parole — and up to 15 years — for anyone previously convicted of a crime of violence or disqualifying felony who is found in possession of a regulated firearm.

It remains unclear whether prosecutors will file written notice seeking mandatory minimum enhancements tied to Harrison's prior assault and weapons convictions, or whether ballistic testing will confirm that the alleged ghost gun found under his mattress matches the six shell casings collected from the scene. Both questions remain open ahead of the December trial.

The shooting took place on the 1600 block of Division Street in West Baltimore's Upton neighborhood, an area historically significant as the childhood and adult residential neighborhood of civil rights pioneer and U.S. Supreme Court Justice Thurgood Marshall, according to the Baltimore City Historical Society. The case echoes another violent crime arrest just blocks away, on the 1900 block of Division Street, that Hoodline reported on in a story about a pre-dawn West Baltimore killing earlier this year.

Citywide, violent crime has trended downward. The Baltimore Police Department reported a 31% drop in homicides and a 24% decrease in non-fatal shootings in 2025, changes local officials have attributed to targeted intervention strategies and increased gun clearances. Whether that trend holds will likely stay in focus as Harrison's case — and others like it moving through Judge Copeland's docket — head toward trial.
