STATEN ISLAND, N.Y. -- The parents of a 17-year-old who committed suicide in October have filed a notice of intent to sue the city, the NYPD, the MTA and the Port Authority, alleging their son might be alive if not for the failed efforts of their employees.

Daniel Lomtevas first threatened suicide in August on the Verrazano-Narrows Bridge, but MTA Bridge and Tunnel officers teamed with NYPD Emergency Service Unit members to bring the teen safely off the span.

Less than two months later, he jumped to his death from the George Washington Bridge after a Port Authority officer unsuccessfully tried to grab Lomtevas.

The notice of intent to sue claims the city and underlying entities are liable for wrongful death and negligence, each in the amount of damages no less than $100 million.

According to the notice, six police officers who were aware of Lomtevas' previous suicide attempt tracked his movements across the city for about an hour from the family's Brooklyn living room despite requests from the family for emergency personnel to intercept the teen.

The notice also alleges that the guardrails at both the Verrazano-Narrows and George Washington bridges allow easy access for people to jump with minimal supervision by authorities.

THE MONTHS BEFORE HIS DEATH

After Lomtevas' first suicide attempt at the Verrazano-Narrows Bridge, he received inpatient care at Richmond University Medical Center in West Brighton, according to the notice. He returned to Brooklyn College and received outpatient treatment from a psychiatrist and a therapist, the notice said.

Prior to his first suicide attempt, he left a four-page note for his parents. He wrote he had "zero excuse as to why I feel this way, or why I let myself fall this far," according to the notice.

"I don't want you guys to worry about me anymore. I don't want to crash and burn even harder than I already did. ... I'm sick of being Daniel."

The city plans to review the notice, a spokesman for the city Law Department said.
