UPDATE: 6/17/26
New findings are shedding light on the tragic death of Deniz, the Central Park carriage horse who tragically collapsed and died in Manhattan last week.
According to reports, a veterinary necropsy conducted at Cornell University found that Deniz had ingested Japanese yew, a plant known to be extremely toxic to horses. The shrub is believed to have been eaten shortly before he collapsed.
The results have sparked debate over how a deadly plant was accessible to a carriage horse in one of the country’s most visited parks.
Questions are now being raised about accountability and whether stronger measures are needed to protect horses from preventable dangers.
Representatives of the carriage horse industry and park officials reportedly disagree over who was responsible for preventing horses from eating potentially dangerous plants.
The findings come as many New Yorkers continue to mourn Deniz’s death and call for greater scrutiny of the conditions faced by carriage horses.
Reports indicate that Deniz had passed a veterinary examination earlier this year, making his sudden death all the more shocking.
While the necropsy may have identified what triggered the tragedy, Deniz’s death has reignited concerns about animal welfare in New York City’s carriage horse industry and intensified calls to end the practice.

A 16-year-old New York City carriage horse named Deniz reportedly collapsed and died in Central Park on Tuesday evening, prompting renewed calls from animal welfare advocates to end the city’s horse-drawn carriage industry.
According to advocacy organizations, Deniz collapsed while pulling a carriage carrying passengers through Central Park. Witnesses reportedly watched as emergency responders rushed to the scene, while shocked onlookers gathered nearby.
The tragic incident comes as supporters of Ryder’s Law prepare to push for the legislation’s reintroduction before the New York City Council. The proposed measure would transition New York City away from horse-drawn carriages, retire the horses to accredited sanctuaries, and establish a transition plan for carriage drivers and workers.
Animal advocacy organization Voters For Animal Rights called for immediate action following Deniz’s death.
“This moment demands more than outrage. It demands action,” the group stated.
Voters For Animal Rights noted that Deniz’s death follows the losses of other carriage horses, including Ryder, Lady, Aisha, Charlie, and Smoothie, and urged city leaders to move forward with Ryder’s Law.
“But doing nothing is not an option. Another horse is dead on the streets of New York City,” the group added.
Animal advocacy organization NYCLASS also condemned the tragedy and renewed its call for legislative action.
“No horse should suffer and die this way in the middle of New York City,” the group stated.
NYCLASS added, “Deniz’s death underscores the urgent need to pass Ryder’s Law before another horse is killed or more people are injured.”
For advocates, Deniz’s death serves as another heartbreaking reminder of the ongoing concerns surrounding horse-drawn carriages in one of the world’s busiest cities. As pressure mounts on elected officials, animal welfare organizations are urging New York City leaders to act before another horse loses their life on the streets of Manhattan.
“How many more horses have to die before real change happens? Deniz should not have died in vain. We urge New York City leaders to pass Ryder’s Law and finally give these horses the protection they deserve.” — World Animal News & Peace 4 Animals
