Police Identify Substance Found In Syringes Related To Churchton Incident

The substance used in several of the syringes tied to a needle-stick incident last week in Churchton was semen, Anne Arundel County police said Friday.

Police said they were unsure if any of those were the syringe used to attack a woman at a shopping center.

Thomas Byron Stemen, of Churchton, was arrested Tuesday and charged with first- and second-degree assault and reckless endangerment.

Additional testing is underway, police said, adding that detectives believe there may be other victims who have not yet come forward. Anyone with information is asked to call the Southern District at 410-222-1960 or the police tip line at 410-222-4700.
