Martino Marcus Young, age 19, of S.E. Washington D.C.,
UPDATE 11/12/2025: Tony Covington, State’s Attorney for Charles County, announced that on Friday, October 31, 2025, Charles County Circuit Court Judge William R. Greer, Jr. sentenced Martino Marcus Young, 21, to 18 years in prison for Armed Carjacking, Armed Robbery, two counts of First-Degree Assault, four counts of Use of a Firearm During the Commission of a Crime of Violence, and related charges.
Upon release, Young will be on supervised probation for a period of five years. If he violates the terms of his probation, he faces an additional 30 years in prison.
On March 6, 2024, officers with the Charles County Sheriff’s Office responded to St. Charles High School for the report of an armed subject.
Upon arrival, they met with a juvenile victim (Victim 2) who reported that he and two friends were confronted and assaulted by four suspects in the school’s parking lot.
A school resource officer also made contact with another victim (Victim 1), who reported that during the assault, he was struck several times in his face with a firearm. The victim fell and lost the key to his vehicle, which one of the suspects used to steal his car. Both victims sustained non-life-threatening injuries due to the assault.
An investigation revealed that the day before the assault, a friend of Victim 1 and Young’s juvenile co-defendant got into a verbal altercation at the school. Later that day, Victim 1 drove his friend to the co-defendant’s apartment complex, but no altercation occurred.
The following day, however, the suspects parked near Victim 1’s vehicle and ambushed him, Victim 2, and another friend as they walked toward the cars. While the third friend was able to escape prior to the attack, Victims 1 and 2 were assaulted. During the attack, one of the suspects brandished a firearm and threatened Victim 1. The suspects then fled the area, with one of them taking Victim 1’s car.
Video surveillance of the assault was captured by school cameras. During the course of the investigation, Young was developed as one of the suspects
During sentencing, Assistant State’s Attorney Kate Edmands, asking for more than 30 years in prison, told the judge that Young was “the mastermind behind all of this.” She furthered, “This case is serious and excessive as they came to a school in Charles County, brought guns to the school, and pistol-whipped victims,” adding that one of the victims had permanent disfigurement.

The facts of the case are as follows:
On March 6, 2024, two St. Charles High School students were assaulted in the parking lot. After the assault, the suspects stole one of the victim’s cars and fled
Detectives pursued leads and developed two individuals as suspects: Martino Marcus Young, age 19, of S.E. Washington D.C., and a 17-year-old male from Waldorf.
The case was presented to a Charles County Grand Jury earlier this month which returned indictments of armed carjacking, armed robbery, robbery, firearms violations, and other related charges.
Arrest warrants were obtained and with the help of the CCSO Warrant Fugitive Unit and the U.S. Marshals Capital Area Regional Task Force, both suspects were arrested on July 24. Search warrants were served and evidence linking the suspects to the case was recovered.
The juvenile was charged as an adult and is being held at the Charles County Detention Center. Young, who was initially arrested in Washington, D.C., was extradited to Charles County on July 29 and is awaiting bond review.
