County Police Arrest Alleged Serial Rapist
Suspect charged in assaults committed between 2007 and 2011 in Gaithersburg, Germantown area
Montgomery County Police
Detectives with the Montgomery County police department’s Cold Case unit have arrested a Germantown man believed to be responsible for three rapes and one sexual assault that occurred between 2007 and 2011 in the Gaithersburg and Germantown areas.
Police charged Marlon Michael Alexander, 39, of Dairymaid Drive with two counts of first-degree rape, one count of second-degree rape, two counts of first-degree sex offense, one count of second-degree sex offense, and one count of attempted first-degree sex offense after his arrest Thursday in a Germantown grocery store. Alexander was also charged with four counts of first-degree burglary because he gained entry into the victims’ homes before assaulting them, police said Friday.
According to a police press statement, Alexander recently became a suspect in the sexual assaults and detectives “obtained his DNA through a search and seizure warrant.
Three of the four assaults occurred within a distance of less than a quarter of a mile. Father Hurley Boulevard separates the two locations of the Germantown rapes.
According to police, the victims include a 68-year-old woman residing in the 20300 block of Beaconfield Terrace in Germantown who was raped twice. In both attacks, Alexander gained entrance to the victim’s home unlawfully in the early morning hours; the first time at 3:20 a.m. on June 19, 2010 and the second time at 12:45 a.m. on Jan. 5, 2011. In the first attack, Alexander held a weapon to the victim’s head and raped her, police said.
Alexander also assaulted an 86-year-old woman at 4:15 a.m. on Aug. 21, 2010 at Churchill Senior Living Center on Father Hurley Boulevard in Germantown. According to police, Alexander was armed with a pair of scissors during the rape and he struck the victim multiple times with his hands before he fled.
The fourth known victim, a 25-year-old Gaithersburg woman, was assaulted at 1 a.m. in her home on Aug. 11, 2007, in the 18200 block of Lost Knife Circle. In that case, Alexander threatened to shoot the victim if she didn’t perform a sexual act, but the victim was able to fight him off, causing Alexander to flee.
Detectives currently do not believe there is any connection between Alexander and his victims other than proximity, but they do believe there could be additional victims. Police will continue to investigate unsolved rapes in the county that could be linked to Alexander.
Alexander is being held without bond in the county’s detention center in Rockville. A bond review hearing is scheduled for Monday in Montgomery County District Court in Rockville.
