QUEENS — An emotionally disturbed woman who shot herself in the head Thursday morning and was declared dead by emergency medical workers was later discovered to be still alive, police said.

Police and emergency workers from Jamaica Hospital responded to a 911 call shortly after 9 a.m. at a home on 115th Street, between 103rd Avenue and Liberty Avenue, in Richmond Hill, police said. There they found a 32-year-old woman lying on her side in a pool of blood with a gunshot wound to her head, as first reported by the New York Daily News. A small rifle was discovered near her body, officials said.

The woman, who was bipolar, had been on the phone with her boyfriend, threatening to kill herself, according to published reports. When the boyfriend, who was in Ohio, heard a gunshot over the phone, he immediately hung up and called the woman's sister, who called 911.

The EMTs couldn’t find a pulse on the woman and declared her dead at 9:34 a.m., officials said.

But at 10:43 a.m. officers investigating the scene heard noises coming from the woman. The same emergency workers were called back to the scene along with a supervisor, police said.

The woman, whose name has not been released, was rushed to Jamaica Hospital in critical condition, according to the NYPD. She later succumbed to her injuries, according to published reports and sources.

“We are currently investigating," said Michael Hinck, a spokesman for the hospital, who declined to elaborate.

Jim Long, a spokesman for the FDNY, which oversees medical-response calls, also said that the incident is "under investigation.”
