Oscar Aguilar, a 21-year-old vet, died after accidentally shooting himself in the head after posing for the deadly selfie.
Earlier, he had allegedly posted photos of himself on Facebook in front of sports cars, sitting on motorbikes and hugging women.
It has been reported that he then borrowed the gun and snapped himself waving it about before accidentally killing himself.
According to the Daily Mirror, neighbour Manfredo Paez, 57, said: ‘I heard a gunshot and then I heard somebody screaming and realised somebody had been hurt.
‘I called the police straight away and when they arrived they found that he was still alive.’
Police said Aguilar had failed to realise the gun was loaded.
