Evidence that paints a picture of the crime scene was presented to the jury in a mass shooting in which three lives were dragged. The case was argued on April 23 in front of the judge of the DC Superior Court, Neal Kravitz.

William Johnson-Lee, 22, Erwin Dubose, 30, Kamar Queen (27) and Damonta Thompson, 28, are charged with conspiracy, two cases of deliberate murder of the first degree, while he is causing more difficult circumstances, two counts of the attack on purpose, and three counts that had to deal with significant body. Donnetta Dyson, 24-year-old Keenan Braxton and 37-year-old Johnny Joyner.

Dubose, Queen and Johnson-Lee each provided nine other owners of a firearm during a violent crime. Queen and Thompson are each with another number of the first degree murder, while it is armed with aggravating circumstances, and Johnson-Lee is accused of two other charges of the same charges. Dubose, Queen and Thompson also have an additional charge to kill on purpose because of one or more attack counts while armed.

Dubose and queen are also charged with a prior conviction due to illegal possession of a firearm. Dubose has additional charges for initial first degree murder while arming and manipulating physical evidence. After all, Queen and Johnson-Lee accuse him of wearing a gun without a license outside of a house or a company.

The incident occurred on September 4, 2021 on the 600 block of the Longfellow Street, NW, and caused three more from injuries.

The 52 -year -old Toyia Johnson and Mussay Resene (32) are charged with the fact of accessory, while they are armed and manipulated with physical evidence for their alleged participation in the support of the other defendants in eliminating evidence and avoiding that they are caught in connection with the case.

The public prosecutor called an analyst of the Ministry of Forensic Sciences (DFS), which documented, photographed, collected and preserved evidence that would have found most evidence of detective and civil servants from the Metropolitan Police Department (MPD) and on -site civil servants. The jury looked at the camera recordings carried with the body with a metal detector who sought additional evidence in the grass.

During the cross-life, Peter Fayne, Johnson-Lee's lawyer, pointed out that an officer in the body camera touched the grass without gloves. The DFS species agreed that this was not a proper protocol and the risk of possible contamination was.

The witness said during the follow-up penalty tracking and in the area where the official touched the grass had not found any additional evidence.

The public prosecutor presented a color diagram with ballistic evidence, including the difficulties found. Two different colors were used to separate the cartridges of 0.40 caliber. The public prosecutor said that this diagram was a reference instrument for the jury.

The defense lawyer of Mussay Resene, Camille Wagner, stated that there is not enough testimony to authenticate the diagram as evidence of separating the residual markings.

The judge decided that “the safest way to get a black and white version of the diagram exists and that the public prosecutor has complied with.

Because of his descriptive caption, Wagner still rejected the diagram and said that the jury would close the separation between certain cases of the caliber of the caliber .40.

Judge Kravitz left the defense that the problems were not big enough to delay the court and approved the ballistic evidence.

The public prosecutor also referred to a former employee of the MPD office for communication department, who published tweets for the agency and designed an MPD press release in which a vehicle was identified in connection with the murders.

David Akulian, Johnson's lawyer, found that the communication person could be the license number of the vehicle or how many passengers could possibly be inside.

The public prosecutor also described an MPD detective who ordered the police to increase the size of the crime scene as soon as he found that there was probably evidence outside the limited borders.

During the intersection, Fayne questioned the effectiveness of the move, and the witness admitted that everyone who had gone through the area could have contaminated the evidence.

The parties should arise again on April 24th.
