Tributes are being paid to two 17-year-old boys stabbed to death at a house party in Milton Keynes.
The victims have been named as Dom Ansah and Ben Gillham-Rice.
Two cousins of the boys laid flowers outside the house where they were killed and said: "Many, many people's hearts are broken."
One of the cousins, who did not want to be named, said: "He's come here with his long-time best friend since childhood, comes to a party and both of their lives just got ripped away from them.
"He was just so respectful to, like, his family and friends."

A double murder investigation is under way but no arrests have been made.
On Sunday, two forensic officers were seen inspecting an object on the driveway of a house in Archford Croft and there appeared to be blood smeared on the front door.

A neighbour said she heard a "commotion" and screaming shortly before midnight on the night of the stabbings.
"The police were here pretty quick," she said.
Another neighbour told BBC News she believed the gathering was a party for a teenage girl living in the house.
Others said they had seen a birthday banner hanging on the door.
