The homicide occurred on October 24 at a home where Lone III and his family lived in the 7900 block of Muncaster Mill Road.

On Monday, October 24 at approximately 9:58 p.m., the Emergency Communications Center (ECC) received a 9-1-1 call for a shooting that had just occurred at a residence in the 7900 block of Muncaster Mill Road. Officers from the 6th District and Fire and Rescue personnel responded and located Ronald Michael Lone III on the back deck of the home suffering from apparent gunshot wounds to the body. Lone III succumbed to his injuries at the scene. The preliminary investigation by detectives indicated that two suspects, dressed in dark clothing and with their faces concealed, entered the home through the unlocked rear door. During the apparent home invasion, one of the suspects shot Lone III. Both suspects then fled from the home.
The Office of the Chief Medical Examiner in Baltimore ruled the manner of Lone III’s death a homicide from multiple gunshot wounds.
During the course of the investigation, detectives discovered that the home where Lone III and his family lived contained a marijuana growing operation. Investigators have reason to believe that the robbery of marijuana may have been the motive in this homicide. Detectives spoke to witnesses who were in the home at the time of the shooting. One witness stated to detectives that he recognized one of the suspects as a former student who attended Magruder High School. This witness, however, did not know the suspect’s name. Detectives later spoke with the School Resource Officer (SRO) assigned to Magruder High School and determined that Sirfleaf was a former student at that school. The witness was then shown photographs of multiple individuals and he identified Mohammed Sirleaf from the photographs as a suspect involved in this homicide. The witness further stated to detectives that Sirleaf has been at the home on prior occasions to smoke marijuana.
Detectives spoke to additional individuals who had knowledge of this homicide and determined that Timario Gregg may have been present in the home with Sirleaf at the time of the shooting. On November 3, Gregg posted a photograph on one of his social media accounts that appeared to show him with a handgun tucked inside his waistband.
On November 14, detectives obtained an arrest warrant for Mohammed Sirleaf charging him first-degree murder, armed robbery, conspiracy to commit first-degree murder, and conspiracy to commit first-degree assault. Sirleaf was arrested on November 16 and transported to the Central Processing Unit (CPU). He is currently being held without bond.
