NYC boy and grandma die of mysterious poisoning 3 months apart

A Brooklyn grandmother and her 4-year-old grandson were mysteriously poisoned within months of each other last year — and now the NYPD is probing who may be behind their deaths after exhuming the elderly woman’s body, police said Thursday.

Tofoon Man, 63,  was rushed to Mount Sinai Hospital after falling ill with sudden stomach pains inside her Mapleton home on Feb. 17, 2021, according to cops. Her health quickly worsened and she was pronounced dead at the hospital the same day.

Three months later, on May 24, 2021, her grandson Wilhelm Ducatl, 4, called 911 with help from someone inside the same apartment to report an intense stomachache and was rushed to Maimonides Hospital in critical condition, according to police. He died two days later.

The NYPD and the Office of the Chief Medical Examiner soon determined the cause of the boy’s death was acute poisoning from thallium —  a metal found in rat poisoning and insecticide that’s also sometimes used for medical tests.

They later exhumed the grandmother’s corpse for an autopsy and determined the same substance had killed her, a police spokesman told The Post.

Little Wilhelm had been living with his grandmother while his parents were at odds, possibly over a custody battle, the spokesman said.

Police have interviewed the mother and not made any arrests in the case, nor have they identified a suspect. The father is not “not a suspect at this time,” according to the spokesman.

Anyone with information on the case should call the NYPD’s Crime Stoppers line 800-577-TIPS.
