A snap-happy tourist visiting New York City reportedly took a photo of a dead person and sat down next to them on a park bench before realising they were deceased.

Portland, Oregon, tourist Vincent Galindo told the New York Daily News he mistook the dead body for a live human being on the bench outside the Vesuvio Playground in SoHo about 5am.

The mistake has emerged after the death had already attracted headlines last week when a group of people in line for cronuts outside the nearby Dominique Ansel Bakery seemed unfazed by having to line up next to the corpse.

The body of Andrew Lang, 47, was one of three discovered in New York City parks over the weekend now being investigated by the medical examiner.

Mr Galindo told the Daily News he initially didn't know the man was dead and took his photograph before sitting down beside him.

'I saw him and thought he seemed so very peaceful,' Mr Galindo told the newspaper.

'After sitting next to him, I realized he was not breathing . . . It was brutal and very emotional.

'My heart goes out for him and friends and family. Very sad.'

On Saturday afternoon, police said a dog walker found the body of a woman, 35, lying in the bushes at Brower Park, in Crown Heights, Brooklyn.

The woman, who was not immediately identified, also had no clear signs of trauma.

In the third find, an unidentified woman, believed to be in her 50s, was found dead at McCarren Park baseball field, Williamsburg, Brooklyn, on Sunday morning.

Witness Molly Pholig tweeted that she was only 'mildly surprised' the sight of the dead man seemed to not faze the people in line

After the 47-year-old man's body was discovered on a bench, one witness said the line to the bakery had to be rerouted so that authorities could recover the man's body

A source had told the New York Post the body was of neighbor Mr Lang, that his death did not appear suspicious and noted he had been dead four about ten hours.

But amid the discovery, witnesses said those in line trying to get their hands on a pastry from the famed bakery did not appear deterred at all by the incident.

In fact, the line had to be rerouted so that authorities could recover the man's body, one witness tweeted as the ordeal unfolded.

'Just watched police relocate the line of people waiting for Cronuts so they could remove a dead body from a nearby bench,' Molly Young tweeted at the time.

She later told the New York Post that she did not see anyone leave the line.

'It didn't put a dent in anyone's appetite,' the 29-year-old told the Post.

Meanwhile, witness Molly Pholig tweeted that she was only 'mildly surprised' the sight of the dead man seemed to not faze the people in line.

'Only mildly surprised that the very visible dead body of a homeless person seemed to not phase (sic) the thirty people in the cronut line,' Pholig tweeted.

'I find it more perplexing than anything,' she later told the Post of the people still in line during the incident.

'It's viscerally shocking to see that, and by the time I got to the office I felt queasy and shaken and not in the mood for breakfast.'

A bakery employee, however, discounted the accounts of the incident shared online, claiming there was no one in line at the time and confirmed a man did notify them of the body, according to the Post.

Following the incident, the medical examiner's office is working to determine the cause of death.
