Another murder was committed by Dana, without her husband being involved. On 14 September 2002, she traveled to Jindřichův Hradec in search of a job and accommodation, before going towards Kardašova Řečice. There she met 78-year-old Maria Čondlová, whose trust was won by the story of being a victim of the floods in Prague. The woman let Dana sleep in her house, and when she came from shopping the next day, she caught her visitor searching for her. Dana attacked the woman, overcoming her and tying her to a chair. She then demanded that Čondlová tell her where she keeps her money. When she refused, Dana put a gag in her mouth, and hit her twice on the head with a roller pin before stabbing in the chest four times. Afterwards, she searched through the house, cleaned it and then slept there for another night. Police investigated this case from the beginning as a murder, and even though they received a description of the offender, the search for her identity proved unsuccessful.
