Two parents and their daughter have died in a house fire in Hemel Hempstead.

Police are investigating a possible murder-suicide after firefighters were called to a blaze at a property in Stuarts Close at around lunchtime yesterday.

Hertfordshire Constabulary confirmed last night that three people had died in the house fire.

The victims were a couple, who were aged 57 and 50, and their 24-year-old daughter.

They have been named by a neighbour as Gary and Caroline Walker, and their daughter Katie.

Their neighbour across the street has today (Monday) described the moment he glanced out his front window and saw smoke pouring out one of the windows of the home.

The 67-year-old man, who called the emergency services shortly after 12.30pm on Sunday, said: "I just looked out the window and saw smoke, it was coming out of their bathroom window.

"If you see smoke, it relates to fire. So I just got straight on the phone to the fire brigade.

"I didn't see any fire, just the smoke."

He said that the family had lived there "for years", and added: "They were such a nice family. Very quiet, but very nice."

Police remain on the scene this morning after launching a major investigation into the fire.

Two forensic vehicles and three police cars sat outside the house, as forensic officers went in and out.

There is no sign of fire damage to the exterior of the home - save for a small, black smoke mark outside the bathroom window.

At around 1pm today, Hertfordshire Constabulary confirmed it had launched a murder investigation but later added that it was "not looking for anyone else in connection to this incident at this time".
