A murder inquiry has begun into the deaths of a teenager and two men after reports of a shooting at a house in Hertfordshire.
A car sped off after the shootings, one neighbour said
Police sealed off the home in Plaw Hatch Close, Bishop's Stortford, after emergency services were called to the property late on Tuesday night.
The three victims were believed to be a 17-year-old boy and two men, aged 33 and 52, police said.
One neighbour said she thought a young girl was in the house when it happened.
Lynne Walford, said she saw the girl, aged about seven, being taken out of the house by police.
"I felt quite guilty because I didn't know there were young children there but she looked fine," she said.
"She obviously was there when it happened, the poor little thing."
Richard Guy, who lives near the scene of the shooting, told BBC News: "I came back from the pub about twelve o'clock and, yeah, there was police here.
"I mean, before I went out I heard a bang and a car speed off quite quickly but it's something that I hear round here quite regularly so I didn't really expect it to be anything, anything bad.
"I've only been here since December. For something to this extent to happen already - it's quite a shock to everyone I think."
Dean O'Connell, who also lives in the close, said: "You don't expect it somewhere like this, but this estate is renowned for a little bit of drugs - most of the trouble here, I imagine, is because of drugs."
Forensic experts were working at the scene and police have been carrying out door-to-door inquiries since the incident, witnesses said.
A spokesman for the East of England Ambulance Service, said: "We were called to the house at 9.40pm - on arrival, three men were pronounced dead at the scene."
