Two gunmen shoot female victim multiple times and drive off.

UPPER MARLBORO, MD (March 6, 2023) – A Prince George’s County jury found 21-year-old Keimoni Sheppard, of Upper Marlboro, guilty of first degree murder in connection with an incident that occurred on March 29, 2021. Sheppard is facing a potential maximum sentence of life plus 20 years in prison and is scheduled to be sentenced on May 5th, 2023.

After a four-day trial and three hours of deliberation, Sheppard was convicted of first degree murder and use of a firearm in the commission of a crime of violence. Co-Defendant Brendan Cooley pled guilty to first degree murder prior to the commencement of trial.

On March 29, 2021, Prince George’s County police officers responded to an address in Suitland for a report of a shooting where they found the body of a female victim in the driver’s seat of a vehicle parked in the driveway of the location. The victim, identified as 30-year-old Marteese Norman, had multiple gunshot wounds to the body and was pronounced deceased at the scene of the crime.

Video footage that captured the shooting showed a dark-colored Jeep Compass back into the driveway where the victim’s vehicle was parked. Co-Defendant Cooley exited the vehicle and fired multiple rounds into the driver’s window of the victim’s vehicle. Sheppard is then seen exiting the passenger side of the Jeep Compass with a handgun and firing multiple rounds into the victim’s vehicle as well. Both suspects re-entered the Jeep Compass and fled the location.

“I want to thank the jury for this guilty verdict against Mr. Sheppard. There is no excuse for taking another human being’s life. I am grateful that we were able to hold the defendant accountable for his senseless and horrible actions. I want to thank the prosecutor assigned to this case for his hard work and diligence. I pray that Ms. Norman’s family finds some peace in knowing that their loved one’s killer has been brought to justice,” said State’s Attorney Braveboy.
