A US man mistakenly shot dead his 15-year-old son while investigating what appeared to be an attempted burglary next door, police say. Jeffrey Giuliano, from New Fairfield in Connecticut, opened fire on a masked teenager outside his sister’s house. Police later told him he had killed his adopted son Tyler. No charges have yet been filed in the case, the BBC reported. “All in all it’s a tragedy,” said state police spokesman Lt J Paul Vance, quoted by an American news agency. According to police, the father was called by his sister, who lives next door, at around 01:00 on Friday (05:00 GMT) when she heard someone outside the house and believed they were attempting to break in.

Mr Giuliano confronted a person wearing a black balaclava and black clothing, and fired his gun when the person lunged at him with “a shiny weapon”. He did not know it was his son until they removed the head covering.
