FREDERICK, Md. —

A 34-year-old Frederick man was arrested after police said he knowingly transferred HIV to women he met on various dating websites and apps.

Frederick County police arrested Rudolph Smith after obtaining evidence during a 21-month investigation that he was actively having sex with women knowing he was HIV positive. 

Police say the investigation began after several women disclosed their belief that Smith infected them with HIV. 

Authorities tested Smith's blood and determined he was HIV positive. After he was made aware of his status, police said Smith continued to meet women on dating sites and have unprotected sex with them without disclosing his diagnosis.

Detectives say prior to their own testing, Smith has been aware of his diagnosis since 2014. 

Smith was indicted by a grand jury on the following charges: 

  • 4 counts: First-degree assault
  • 4 counts: Reckless endangerment
  • 4 counts: Knowing transfer of HIV prohibited

Smith is currently being held on $100,000 at the Frederick County Adult Detention Center, according to officials.

Anyone who may have had a sexual relationship with Smith around or after July of 2017 is asked to call police at 301-600-TIPS (8477), text 240-674-8477 or email FPDcrimetip@frederickmdpolice.org
