Story summary

On June 9, Deniz, a 16-year-old carriage horse in Central Park, died suddenly after eating Japanese yew berries. The horse's owners, Nurettin and Ummet Kirbiyik of Arsian Horse Carriage, filed a "notice of claim" on September 8 against multiple city agencies including the City of New York, NYC Parks, the Health Department, the Department of Consumer and Worker Protection, the Department of Transportation, and the Central Park Conservancy. The necropsy by Cornell University's Animal Health Diagnostic Center confirmed Deniz suffered from yew toxicosis due to ingesting Taxus berries. The brothers allege that despite knowing about the toxicity of Japanese yew, authorities failed to prevent horses from accessing these plants or provide adequate warnings. They are seeking at least $50,000 in compensation for their loss.

Claims (16 extracted, 5 hedged)

The owners of Deniz, a 16-year-old carriage horse who died suddenly in Central Park on June 9, have filed a “notice of claim” — a required step before suing the city — alleging that the horse died from eating Japanese yew planted along the park’s carriage drives. uncertain

horse → die → drives

who → file → Transportation

The claim alleges Deniz ate the berries near the East Drive, just north of East 90th Street, before collapsing roughly 45 minutes later near the West Drive and dying. uncertain

Deniz → allege → Drive

According to the claim, a necropsy by Cornell University’s Animal Health Diagnostic Center found evidence of Japanese yew and diagnosed the late beast with Taxus, or yew toxicosis. uncertain

necropsy → accord → Taxus

The owners allege the shrubs were planted within reach of carriage horses and that there were no warnings, barriers or signs alerting drivers. asserted

shrubs → allege → drivers

And they claim the city and the Central Park Conservancy knew — or should have known — of yew’s toxicity. uncertain

city → claim → toxicity

The brothers are seeking at least $50,000 — the horse’s value plus veterinary and diagnostic costs, transportation expenses and business losses. asserted

brothers → seek → 50,000

The claim also demands that the city and Conservancy survey and address toxic vegetation near carriage routes. uncertain

city → demand → routes

“[The horse carriage union] has now demonstrated how their own negligence has resulted in this unfortunate incident, since NYC Parks rules plainly forbid horses from eating vegetation anywhere across our 843 acres,” a spokesperson for Central Park Conservancy said in June. asserted

spokesperson → demonstrate → June

“The same rule requires carriage drivers and operators to attend to their horses at all times in order to keep them safe and healthy. asserted

rule → require → them

Perhaps if they had, Deniz would not have suffered as he did, and died,” it said. asserted

it → have → ?

The CPC also said it supports a ban on carriage horses in the park. asserted

it → say → park

Robert Hantman, the brothers’ lawyer, responded saying “it’s ridiculous to ban a tradition that’s almost as old as the park itself” and that it’s “not surprising” the CPC is looking for a scapegoat. asserted
