Prosecutors believe Hupp told Gumpenberger that she wanted him to help her reenact a 911 call. Investigators also learned that Hupp had unsuccessfully tried to lure two others to her home with claims that she was a producer for “Dateline,” NBC’s newsmagazine. Hupp was captured on video at one of those people’s home. Investigators also tracked her phone to the Dollar Tree where she bought the knife, and to Gumpenberger’s apartment, where they believe she picked him up.

She also stabbed herself in the neck and arms after her arrest using a pen, which Lohmar called “evidence of consciousness of guilt.”

St. Charles County Circuit Judge Jon Cunningham ruled in January that prosecutors would also be able to discuss some aspects of the Faria murder to try to show Hupp’s motive. They would not have been able to blame Hupp for the Faria murder, but prosecutors have said they had no plans to do so at trial.
