Accused Serial Rapist, Marlon Alexander, Held Without Bond



He remained free for years after committing the crimes he has been charged with, but he won’t be allowed his freedom as he awaits trial, that is the decision by a Montgomery County District Court Judge on Monday, at a bond hearing for the Germantown man arrested in connection to a series of rapes in Germantown between 2007 and 2011.

Marlon Alexander, 39, of the 13000 block of Dairymaid Drive was denied bail during a bail review hearing in front of Judge Rand Gelber in Rockville. According to reports, Judge Gelber said, “Due to the nature of the crimes, the suspect poses a serious threat to the community.”

Alexander, who is married with four children, was arrested by Montgomery County police detectives on Thursday, Sept. 13 while he shopped at the Safeway store in Germantown Town Center. He is charged with for two counts of first-degree rape, one count of second-degree rape, three counts of first-degree sexual offense, four counts of burglary, and one count attempted first-degree sexual offense.


At a press conference held Friday afternoon, Montgomery County Police Chief Thomas J. Manger announced that detectives had arrested Alexander, through the use cutting-edge technology which was first used to capture the so-called Gold State Killer, Joseph James DeAngelo in April.

According to police, detectives have been investigating a series of four burglaries and rapes in which the same suspect left DNA at multiple crime scenes. After obtaining a warrant for and arresting Alexander, a sample of his DNA was taken. Yesterday, the DNA sample provided by Alexander was submitted to the department’s crime lab for analysis. The DNA was analyzed and matched the DNA samples left by the suspect in the four offenses.

Alexander began his series of burglaries and rapes a little over 11 years ago on August 11, 2007, at approximately 1:00 am when police say that he gained entry into the home of a 25-year-old woman, while she was living in the 18200 block of Lost Knife Circle in Gaithersburg. He put an unknown weapon to her head and threatened the victim that he would shoot her if she did not perform a sexual act. A struggle ensued, and the suspect fled from the residence. Police said that the suspect left some DNA evidence at the scene and it was recovered in this case.

The next attack took place three years later on June 19, 2010, when he gained entry into a 68-year-old woman’s home in the 20300 block of Beaconfield Terrace in Germantown at 3:20 am and raped her. The suspect left DNA evidence which recovered in this case.

The next attack took place two months later on August 21, 2010, at approximately 4:15 am, when the suspect forced entry into the 86-year-old woman’s apartment at the assisted living center in the 2100 block of Father Hurley Boulevard in Germantown and raped her. Suspect DNA recovered in this case matched the suspect DNA recovered from the June 19, 2010, sexual assault.
