In 1997, she was raped by a fellow employee and, in her words, she suffered from psychological trauma and then began to heavily abuse drugs.
On 16 November 2001, the Stodolas decided to rob their 75-year-old neighbour Jaroslav Šanda from Slavošov, who was staying with Dana's mother.
While Jaroslav sneaked out of the house in the early morning, Dana talked to her mother in the kitchen, assuring her that her husband was still asleep.
Jaroslav hid behind a curtain in the main hall, and when Šanda returned, he was knocked down and forced to give his attacker 40,000 crowns.
When she refused, Dana put a gag in her mouth and hit her twice on the head with a roller pin before stabbing her in the chest four times.
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.
Jaroslav stunned the man with a heavy blow to the head and then brought him to the ground, where he tried to strangle him with a phone cord behind a beam.
After he left, Dana poured water and Helena's wrist to make it look like she had killed Dagmar and then committed suicide, leading to her mother's heart failure.
However, Božena had managed to survive the attack, and gave a very incoherent testimony, describing the offender as a tall man living in the hostel.
The story was repeatedly connected to Jaroslav Stodola, who surprisingly told investigators he knew he was "suspected" of murder.
[3] Jaroslav's psychological condition rapidly deteriorated after the murders in Brněnec, later attempted suicide by taking sedatives in combination with alcohol.
Jaroslav later learned of a rich pensioner who lived in Onšovec, and at the end of January, the pair went to the place of the alleged residence, but could not locate the house.
Jaroslav then rang the door and asked for water for his pregnant wife, who supposedly fainted in front of the house.
When the retiree pushed through the gate, Jaroslav threatened him with a knife and forced him to enter the basement, where they locked him and speedily searched through the house, but only stole a cell phone and some sweets.
While leaving, they encountered a policeman who had previously carried out investigations in connection with the suspected series of seniors' death in Slavošov and the surrounding area.
Based on this crime, the double murder investigation in Brněnec, where the Stodolovis lived, was renewed, of which Jaroslav was originally suspected.
During the interrogations, Jaroslav insisted that only he had murdered, but during the reconstruction of the crimes, it turned out that he had no idea of a wound on Helena Cerháková's hands.
Stodola refused to admit that his wife had anything to do with the crimes, but the turnaround occurred when she began to testify about the murder of Maria Čondlová in Kardašova Řečice.
The crime scene was described very precisely, and Jaroslav, according to his own words at this moment, finally admitted Dana's guilt.
