The baby girl of an accused poisoner said to have given deadly thallium to her mother so he could seize her estate has died.

Manuel H. from Huerth, Germany, is accused of administering the metal to three women in a sick plot to inherit their assets.

The baby’s mother Yvonne K. survived the murder bid.

Now – local media have revealed – the couple’s four-month-old daughter has mysteriously died.

Cologne district court spokesman Jan Orth revealed on Tuesday, 26th July, that the infant had passed away.

The court has asked for an autopsy to be carried out on the young victim to clarify whether her death was related to her mother’s poisoning.

H., 42, is accused of poisoning his estranged wife Tina H., 35, his new partner Yvonne K., 36, and her 92-year-old grandmother.

He is said to have doped them with injections of soluble thallium salts, once used in rat poisons and insecticides.

Tina and Yvonne’s grandmother died, while Yvonne survived.

She was pregnant at the time and gave birth to a daughter in early March this year.

H. is currently charged with two counts of murder and one of attempted murder in conjunction with attempted termination of pregnancy.

The public prosecutor has listed aggravating factors of insidiousness and cruelty.

According to the charge sheet, the male nurse administered the thallium to the three women in 2020 and last year.

It can cause, among other things, a high resting heart rate, cramps, organ damage and bleeding in the gastrointestinal tract.

His trial will begin at the Cologne district court on 19th September.
