A longtime taxi driver has been missing for eleven days, prompting fears of suicide among family members and fellow cabbies, who say the driver was facing the same financial struggles that led four other professional drivers to take their own lives in the last six months.

Yumain “Kenny” Chow, 56, was last seen on May 11th. His cab was later recovered at 86th Street and East End Avenue, just steps from Gracie Mansion. According to the Taxi Workers Alliance, a nonprofit group that represents drivers, Chow was "losing weight, sleeping less, talking about increasing desperation. His wife was diagnosed with stage 4 cancer in October and he had been worried about paying for healthcare and losing their home as he struggled to make payments on his medallion and as his income from driving dwindled."

He reportedly owed $700,000 on his taxi medallion, which he purchased with loans in 2011, when the tin licenses were at their most expensive. Since then, the value of the medallions have plunged dramatically, as hundreds of thousands of Ubers and other ride-hail companies have flooded the streets of New York, while successfully avoiding meaningful regulation from the city's elected officials.

On Tuesday, Chow's brother and daughter, along with TWA leaders and others drivers, rallied at the Upper East Side corner where the abandoned vehicle was found. "He's working so hard. He's working seven days a week," said Chow's brother, Richard, who is also a medallion owner-driver, and is $400,000 in debt. "I hope my brother comes home safely."

Chow's siblings were joined by TWA founder Bhairavi Desai, who called on the city to take action against the ride-share companies, adding, "We don't want to be here talking about the possibility of another driver brother gone too soon."

In the wake of the four driver suicides, some city officials have signaled a willingness to revisit the issue of Uber regulation. A newly-formed City Council Committee on For-Hire Vehicles is currently considering seven bills aimed at curbing the ride-hailing services. Those include a long-stalled proposal to place a one-year cap on for-hire vehicle licenses, and a package of regulations proposed by Committee Chair Ruben Diaz Sr., which would create restrictions on the companies’ bases, a prohibition on drivers working for more than one app-based service, and a $2,000 yearly license fee for all app-based vehicles.

On a recent Brian Lehrer appearance, Mayor de Blasio expressed support for some measure of regulation, saying, "I think the caps are the kind of thing we need to talk about again because this situation has gotten worse since then, both in terms of the pressure that has been put on the medallion owners and everyday taxi drivers."

Another rally in support of the cap, and in solidarity with the struggling drivers, is planned for outside City Hall next Tuesday.

If someone you know exhibits warning signs of suicide: do not leave the person alone; remove any firearms, alcohol, drugs or sharp objects that could be used in a suicide attempt; and call the U.S. National Suicide Prevention Lifeline at 800-273-TALK (8255) or take the person to an emergency room or seek help from a medical or mental health professional.
