Family members have paid tribute to a “loving” young man who police say was assaulted by a group of masked men and then stabbed to death.
Patrick Gomes De’Almeida was one of two men who was found with stab wounds outside a block of flats in Morden, south west London on October 1.
Officers believe three masked suspects assaulted the 25-year-old outside before he was fatally stabbed.
They fled the scene in a car.
A second man, aged 33, was taken to hospital with injuries which were not life-threatening or life-changing.
In a tribute released by Patrick’s family, they said: “P had a heart of gold. He was loving, caring and full of life and laughter.
“You always knew when P was in the room. He had the gift of making people smile. P will be greatly missed by his family and friends.
“Life will not be the same. As he always said ‘It’s not a party without P’.”
The week before Patrick’s murder his white Volkswagen Scirocco was deliberately damaged.
The damage is believed to have been done in the evening of Wednesday September 23, or in the early hours of the following day.
Officers are investigating whether the two incidents are linked.
DCI Helen Rance, who is leading the investigation, said: “Patrick’s family are heartbroken that he has been taken from them, and I and my team are working around the clock to piece together what happened and find out who is responsible.
“Those responsible for this vicious attack are dangerous, and I know there are others out there who have information.
“It is vital that they come forward, whether by speaking to us or anonymously to Crimestoppers, and share what they know.
“I want to speak to anyone who was in the London Road area close to Grosvenor Court and Homefield flats in the evening of Wednesday, 23 September, or in the early hours of Thursday, 24 September, or between 22:00hrs and 23:00hrs on Thursday, 1 October in the same location.
“We are working tirelessly to track down the perpetrators but the public also play a huge role in helping to both prevent and detect crime.
“We need their help to identify those willing to commit terrible acts and carry weapons.”
