A family in Germany is demanding accountability after the brutal death of artist Kamilla N., 40, who was murdered while voluntarily undergoing treatment at a Munich psychiatric facility.
Kamilla was staying at the Isar-Amper Clinic for treatment in May 2022 when she was placed next door to Jayson David B., a Brazilian national and former trans sex worker, who had been admitted the previous day under alarming circumstances.
According to reports, the trans man had killed his own dog and explicitly warned authorities, saying, “Next up is a human.”
Despite this threat, Jayson David B. was allowed to move freely within the locked ward, and early on May 31, 2022, he attacked Kamilla.
According to court findings, he struck her with a piece of a shower curtain rod and strangled her, believing she was a witch, as part of a delusional episode linked to his paranoid schizophrenia. The coroner ruled that she officially died from asphyxiation.
He then threw mattresses and bed linen over her body and set fire to it, even taping off the fire alarm.
Only when the alarm was eventually triggered did the clinic staff realize what had happened.
In 2023, the Munich Regional Court ruled that the Brazilian national could not be held criminally responsible due to his severe mental illness. He was convicted of manslaughter and permanently committed to a secure psychiatric institution.
The court acknowledged that Jayson David B. had believed he was acting on “orders from the devil” and was mentally unfit to stand trial for murder.
However, Kamilla’s family has not found peace and has fought to hold the clinic accountable, accusing the institution of gross negligence. Despite the trans killer’s known history of violence and explicit threats, he was not properly medicated, closely monitored, or restricted in his movements within the ward, the family argues.
“The clinic failed Kamilla,” said Wiarda in a statement to Bild. “A dangerously ill man was allowed to roam freely in a closed psychiatric ward, with insufficient supervision and medication. This was not just a medical error — it was a catastrophic breach of duty.”
The family’s legal efforts hit a wall in January 2024, when Munich prosecutors dropped an investigation into possible negligent homicide by clinic staff, citing insufficient evidence of wrongdoing. But, lawyers for the victim’s family say the investigation was superficial and failed to consider a private forensic report that identified “clear and serious treatment errors.”
“The public prosecutor never conducted an independent investigation,” lawyer Jella von Wiarda claims. She has since initiated legal enforcement proceedings with the Munich Higher Regional Court, seeking a reopening of the case.
“The family can no longer accept the inaction of the Munich judiciary,” Wiarda added. “They demand clarity — because what happened to Kamilla must never happen again.”
