Murder squad detectives have revealed that a 24-year-old man killed in a Nottingham garden had been shot in the head.
Police were called to the property on Heatherington Gardens, Top Valley, at about 0050 BST on Saturday.
Father-of-one Mark Shaw, from Winterton Rise, Bestwood, was pronounced dead at the scene by paramedics.
A spokeswoman for Nottinghamshire Police said officers were following a number of lines of inquiry.
Detectives said the shooting was not a random attack and Mr Shaw is thought to have had a connection to the gunman.
In a statement, Mr Shaw's family said: "Mark was a loving father to a two-year-old son and a caring son and brother.
"He was popular and kind and had a great sense of humour. We are all devastated by what has happened and will miss him dearly."
Ch Insp Matt McFarlane said: "We do not believe this is a random attack and know that the key to finding who is responsible lies within the community."
Officers are continuing to carry out high visibility patrols in the area.
A cordon around the area is set to stay in place until Monday.
Police have appealed for anyone who was in the area at the time to contact them.
