Possible Biased-Based Vandalism to Home

Detectives from the Montgomery County Police Department – 3rd District Investigative Section are investigating a possible biased-based theft and vandalism that occurred at a residence in the Four Corners area of Silver Spring.

On Sunday, November 20 at approximately 7:22 a.m., 3rd District officers responded to a home in the 200 block of Williamsburg Drive for the report of a theft and vandalism.   The preliminary investigation by detectives revealed that earlier that morning, the homeowner had discovered that a swastika had been spray-painted on the front storm door to his home.   The homeowner also reported to detectives that an American flag, that had been hanging from a tree in his yard, had been stolen.

During the investigation, detectives determined that in late October, the homeowner had a “Trump/Pence” election sign stolen from the front yard of his home.  Detectives also confirmed that on November 16, the homeowner reported to MCP that unknown suspect(s) had thrown eggs at his home.  Detectives believe that the homeowner’s political affiliation may be the motive for these thefts and vandalisms.

Holiday Alcohol Task Force Underway; Police Urge Public To Choose a Sober Driver

With the holidays approaching, there will be an increase in social events and parties that involve the consumption of alcohol.  According to the National Highway Traffic Safety Administration (NHTSA), from 2011-2015, twenty-eight percent (3,983) of all people who lost their lives in a traffic crash during the month of December died in a crash that involved a driver with a BAC of .08 or higher.

The Montgomery County Police Alcohol Holiday Task Force, comprised of officers from the Alcohol Initiatives Section and patrol officers from the six police districts, as well as officers from the Gaithersburg City Police Department, the Maryland National Capital Park Police Department (Montgomery County Division), Maryland State Police, the Montgomery County Sheriff’s Office, and the Takoma Park Police Department, will be devoting their full time and attention to detecting alcohol-related offenses this holiday season.  The task force began on November 16 and will continue through January 7, 2017.

The task force will focus on enforcement of offenses to include:

  • Enforcement of traffic laws in areas known for a high number of alcohol-related tragedies with the goal of getting drunk or drug-impaired drivers off the road.
  • Compliance checks of businesses who hold alcohol licenses by using underage volunteers to attempt to purchase alcohol at establishments (ensuring that shopkeepers are careful not to sell alcohol to minors).
  • Responding to calls for underage drinking parties.  All attendees are screened for alcohol usage, and those who are under age 21 are issued citations. Every person is then ensured a safe ride home.  Parents of juveniles are notified to come and get them. Any parent or other adult who hosts can be held liable and can be issued a citation.  An adult can be held criminally liable if he/she provides alcohol to an individual under 21 years and he/she knew or reasonably should have known the individual would operate a motor vehicle and did operate the vehicle under the influence of alcohol and caused serious injury or death (Alex and Calvin’s Law).
  • Sobriety checkpoints: The location of the checkpoints is based on collision and traffic data focusing on areas that drivers are most at risk for encountering impaired drivers.
  • Responding to calls for service regarding intoxicated persons.

The Montgomery County Police Department wants to remind residents that they can assist in combating alcohol-related crime and collisions this holiday season:

If you plan on drinking alcohol this holiday season, include a sober driver in your plans:

  • If you will be drinking, do not plan on driving. Plan ahead; designate a sober driver before the party begins.
  • When you know you’ll be drinking, leave your keys at home or give them to someone else.
  • If you have been drinking, do not drive—even a short distance. Call a taxi, Uber, phone a sober friend or family member, use public transportation or call Washington Regional Alcohol Program’s SoberRide at 1-800-200-TAXI (The free program is offered nightly from December 16, 2016 to January 1, 2017.

If you believe you are observing a driver impaired by alcohol or drugs:

  • Call 911.  If possible, and without putting yourself in danger, obtain the license plate of the vehicle, the direction of travel of the vehicle, and a description of the vehicle (make, model, color).

If you have information on establishments that are selling alcohol to youth under 21 or over serving patrons:

  • If it is occurring at the present time, you can call the police non-emergency number at 301-279-8000.

Update: Two Suspects Charged in Gaithersburg Homicide

Detectives from the Montgomery County Police Department – Major Crimes Division have arrested and charged Mohammed Sirleaf, age 20, of the 17700 block of Towne Crest Drive in Gaithersburg for the homicide of 23-year-old Ronald Michael Lone III.  The homicide occurred on October 24 at a home where Lone III and his family lived in the 7900 block of Muncaster Mill Road.  Investigators have also arrested and charged Timario Makaveli Gregg, age 19, of the 13800 block of Castle Boulevard in Silver Spring, with possession of firearm by a minor.

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.

On November 14, detectives obtained an arrest warrant for Timario Gregg charging him with possession of a firearm by a minor.  Gregg was arrested on November 16 when he was found inside of a stolen vehicle in the 12900 block of Middlebrook Road in Germantown.  Gregg was transported to CPU and is currently being held without bond.
