Mass Shooter Charged With 50 Counts Takes a Plea for Three

A teenage defendant accepted a plea deal on Aug. 2 that reduced a 50 count indictment to three charges for his involvement in a mass shooting. The case was argued before DC Superior Court Judge Anthony Epstein. 

Byron Matthews, 19, was charged with eight counts of assault with significant bodily injury while armed, eight counts of assault with intent to kill while armed, nine counts of assault with a dangerous weapon and 20 counts of possession of a firearm during a crime of violence for his involvement in a mass shooting  that resulted in gunshot wounds on eight people, which occurred on April 21, 2023 on the 500 block of LeBaum Street, SE and the 2900 block of 2nd Street, SE. 

Facing 50 counts for his alleged involvement in the mass shooting, Matthews accepted the plea deal which was offered by prosecutors. 

The deal required him to plead guilty to assault with significant bodily injury while armed for the shooting that occurred on 2nd Street, SE, and assault with intent to kill and possession of a firearm during a crime of violence for the shooting that occurred on Lebaum Street, SE.  In exchange, the prosecution agreed to dismiss all other charges in the matter, and another case in which he’s accused of carrying a pistol without a license and assault on a police officer.

Through the deal, parties agreed that the required sentence would be a fully executed 12 years of incarceration, with five years of supervised release.

Judge Epstein stated he won’t accept the plea offer until a pre-sentence report is made. 

Molly Bunke, Matthews’ attorney, told the court she plans to conduct a Youth Rehabilitation Act (YRA) study prior to final sentencing. Defendants sentenced under the YRA effectively have their cases sealed if they successful complete the terms of sentence.

Parties are set to reconvene on Nov. 22. 

Lawyer Conflict of Interest Issue Looms Over Murder Trial

Prosecutors alerted DC Superior Court Judge Robert Okun about a possible conflict of interest issue facing a homicide defendant’s attorney in an Aug. 2 hearing. 

Tyree Irving, 27, is charged with first-degree murder, possession of a firearm during a crime of violence, unlawful possession of a firearm by a convict, and two counts of obstruction of justice for his alleged involvement in the homicide of 22-year-old Davane Williams. The incident occurred on Jan. 15, 2019, on the 1200 block of North Capitol Street, NW. 

At the hearing, prosecutors told Judge Okun about described a potential conflict of interest issue during the trial, stating that Irving’s defense attorney, Madalyn Harvey, and a the attorney for a key witness in the case, both worked at the DC Public Defender Service (PDS) at the same time. 

Prosecutors worry that Harvey and the witness’ attorney may have shared important information about the case.


Claire Roth, PDS’ Special Counsel on Ethical Conflicts, told Judge Okun, “From what I know right now, I don’t believe there’s a conflict.” 

However, the prosecution said this potential conflict could result in a mistrial adding “this is a serious appellate concern.”

In response, Roth assured, “I can tell the court, as an officer of the court, that there was no information sharing.”

Judge Okun did not make a ruling and stated that he would, “do the best I can to resolve this before the trial date,” which is slated to begin Aug. 19.

Parties are slated to reconvene Aug. 8.

Judge Modifies Stabbing Defendant’s Release Conditions

DC Superior Court Judge Anthony Epstein modified home confinement and GPS monitoring for an stabbing defendant on Aug. 2.

Wali Shabazz, 50,  is charged with second-degree murder while armed for his alleged involvement in the fatal stabbing of 41-year-old Martin Gross Jr. outside a stadium on the 100 block of T Street, SW. The incident occurred on April 27. 

Since Judge Epstein found the prosecution met the requirements of probable cause against Shabazz on May 8, he has been subject to home confinement and GPS monitoring, with permission to leave the house for his job. 

At his bond hearing on Aug. 2, Shabazz’s attorney, Michelle Stevens, requested stepping down ome confinement as Shabazz had been fully compliant with his release conditions. 

The prosecutor countered that it had only been a few months since Shabazz’s arrest and that it would be premature to alter any of his release conditions. 

Judge Epstein granted the defense request citing Shabazz’s very limited criminal history and stating that “the victim was the primary aggressor,” although he did acknowledge that “Shabazz’s [alleged] response was out of proportion.”

Judge Epstein granted a new release order in which Shabazz would no longer have home confinement and his GPS monitor would be removed. The directive only required Shabazz to check in with the Pretrial Services Agency (PSA) as directed by his case manager. 

Parties are slated to reconvene on Jan. 31, 2025.

Defendant Pleads Not Guilty to Three Carjackings at Arraignment

A carjacking defendant pleaded not guilty before DC Superior Court Judge Robert Salerno on Aug. 2. 


Dennis Vanison, 29, is charged with armed carjacking and carrying a pistol without a license for his alleged involvement in three carjacking incidents. The first occurred on the 2400 block of Wagner Street, SE on May 2, and the following two occurred on the 3300 block of Martin Luther King Jr. Avenue, SE on May 3. 

According to court documents, an individual identified as Vanison and another suspect stole the first victim’s white Chrysler while he was making a DoorDash delivery on May 2. Vanison was not the suspect who pointed the firearm at the victim, according to prosecutors. 

The next day, according to court documents, a separate victim called the Metropolitan Police Department (MPD) when they found Vanison unresponsive at the wheel of their family vehicle. The driver’s door and trunk were open, and a firearm was on the floorboard.

At the hearing, Jesse Winograd, Vanison’s defense attorney, alerted the court of his intent to plead not guilty to all charges and asserted his constitutional rights, including the right to a speedy trial. 

Parties are slated to reconvene on Aug. 14.

A homicide case was delayed due to the defendant’s failure to appear in court before DC Superior Court Judge Robert Okun on Aug. 2. At issue was a death in the family.

Andre Johnson, 31, is charged with second-degree murder for his alleged involvement in a vehicular accident which resulted in the death of 19-year-old Madison Jones, which occurred at the intersection of 11th Street and Pennsylvania Avenue, SE on June 6, 2023.

At the hearing, US Marshals alerted Judge Okun that Johnson had not gotten on the bus to be transported from the DC Jail to the courthouse.

Parties are set to reconvene Sept. 9.

Teen-Age Tryst Leads to Shooting, Says Prosecution

Defense attorney Matthew Rist told  DC Superior Court Judge Rainey Brandt at a hearing on Aug. 2 that his client Antoine Johnson‘s constitutional right to due process has been violated in the wake of a shooting.

Johnson, 28, is charged with two counts of assault with intent to kill while armed, two counts of assault with a dangerous weapon, four counts of possession of a firearm during a crime of violence, unlawful possession of a firearm, carrying a pistol without a license outside a home or business, unlawful discharge of a firearm, possession of an unregistered firearm, and unlawful possession of ammunition. These charges stem from his alleged involvement in a non-fatal shooting on May 21, 2023, on I-695 southbound near exit 2B. No injuries were reported from the incident.

According to court documents about the shooting, the victim was the father of a 17-year-old boy who was found in bed with his 14-year-old girlfriend earlier the same day by the girl’s parents. They called the police to arrest the boy, but the police arrested the girl’s father for assaulting the boy and allowed the victim to drive his son home. 

A police officer present at that arrest testified that he recognized Johnson there from a previous arrest and heard him say to the girl’s mother, “Auntie, I got this.” Court documents state that police body-worn camera footage showed an individual identified as Johnson telling the girl’s mother, “We ain’t doing no talking. I’ve seen his face.”

The victim and his son told police they saw a white sedan following them as they drove away. When both vehicles were slowed by heavy traffic, the driver of the white sedan shot at the victim, shattering the front side windows on the victim’s car and leaving five bullet holes in the driver’s side doors.

According to arrest documents, the victim’s son described the shooter’s distinctive facial tattoos to police and testified to having seen him earlier at his girlfriend’s residence.

Judge Brandt called the Aug. 2 hearing because the deadline to file motions for Johnson’s Sept. 16 trial had passed without any filings from either party.

Rist said he plans to file a motion arguing that the late disclosure of the cell site data information is a constitutional violation, stating it is too close to the trial date for the defense to make any effective use of the information. If Judge Brandt denies the motion, he will need to find an expert witness to testify regarding cell site data.

Rist said he expected to receive DNA testing results by the end of the day on Aug. 2. The prosecution said they may need to call an expert DNA witness, depending on what the results indicate.

The parties agreed to reconvene in a week to determine whether the Sept. 16 trial date is still feasible.

The next hearing in this case is scheduled for Aug. 9.

Victim’s Mother Begs Judge, ‘Make Sure He Can’t Do It to Anyone Else’s Child’

The mother of a homicide victim spoke in opposition to a plea deal that would sentence her son’s shooter to 13-and-a-half years in prison during a hearing in front of DC Superior Court Judge Rainey Brandt on Aug. 2.

Delonte Jackson, 25, was originally charged with two counts of first-degree murder while armed, armed carjacking, three counts of unlawful possession of a firearm, and three counts of possession of a firearm during a crime of violence for his involvement in the death of Artavarn Wagner, 44, on March 3, 2022, on the 1700 block of Gales Street, NE. 

Through his defense attorney, Megan Allburn, Jackson pleaded guilty to voluntary manslaughter while armed on Aug. 2 as part of a plea deal. In exchange, the prosecution agreed to dismiss all other charges and to ask Judge Brandt for a 13-and-a-half-year sentence to run concurrently with a federal prison term of unspecified length that Jackson is already serving for felony possession of a firearm and ammunition. 

“He needs life without parole, since we don’t have the death penalty,” Wagner’s mother said about Jackson. “He shot my child like a dog. He ran him down and shot him like a dog.”

“I’ve had three ministrokes because of this. My health is bad,” Wagner’s mother told the court. She detailed mental health struggles suffered by Wagner’s children that she attributed to Wagner’s killing.

“I beg Your Honor to take into account the damage he has done out here and make sure he can’t do it to anyone else’s child,” Wagner’s mother urged Judge Brandt.

“I can only imagine–I can’t imagine what Ms. Wagner and her family have gone through,” Judge Brandt said. “I do believe Ms. Wagner said some things that Mr. Jackson needed to hear.”

The maximum sentence Jackson could receive for a voluntary manslaughter charge is 30 years’ imprisonment and/or a fine of $250,000. 

Judge Brandt told Jackson that she will decide at his sentencing whether to impose the sentence agreed in the plea deal. Since the plea follows Rule 11(c)(1)(c) of the Federal Rules of Criminal Procedure, Jackson has the right to withdraw his guilty plea if Judge Brandt does not accept the sentencing request.

“This is a process. I’m sure I’ll hear more at the sentencing, but we aren’t there yet,” said Judge Brandt.

In their proffer of facts, the prosecution said that surveillance video showed Jackson approaching Wagner on the street, chasing him into an alley, and shooting him multiple times before driving off in Wagner’s vehicle.

According to the prosecution, Jackson was wearing a court-ordered GPS monitor that showed him to be at the locations where Wagner’s vehicle was spotted on surveillance video during the hours following Jackson’s shooting. 

The prosecution said that DNA and firearm evidence corroborated their case against Jackson.

Under oath, Jackson said that the proffer of facts was accurate.

Allburn asked Judge Brandt to postpone Jackson’s sentencing until after November, to allow Jackson to complete the educational program he is pursuing at the DC Correctional Treatment Facility (CTF).

The sentencing is scheduled for Dec. 13.
