Authorities in Hamburg arrested a 42-year-old woman suspected of attempting to murder her former partner’s 20-year-old son by sending him poisoned chocolates. The package, which was mailed in June, contained pralines laced with substances intended to cause harm.

Subsequent investigations identified the substance as thallium nitrate, a heavy metal capable of causing nervous system and kidney damage, which can be potentially fatal. Following the victim’s decision to alert police, the suspect was placed in pre-trial detention. A search of the suspect’s apartment in Altona-Altstadt also led to the discovery of dangerous chemicals, necessitating the involvement of specialized fire department teams.
