The mother of a man who was found murdered in Stoke-on-Trent has paid an emotional tribute to her son.
Pete Summers was found with serious head injuries
The body of Pete Summers, 35, was found in a flat where he was staying in Squires View, Shelton. He had suffered head injuries.
His mother, Stella Parsons, said Mr Summers had been very close to her, but had battled with drug addiction in the years since leaving school.
Police have renewed an appeal to the public for information.
In a statement, Ms Parsons said her first son was a "lovely child" whose life began to change after he was introduced to drugs at school.
"It didn't take long before they took over what I can only say was a thoughtful, loving and respectful young man.
"Battling with his drug addiction, Pete was in and out of prison."
Ms Parsons described a warm relationship her son had with his former partner, with whom they had two boys.
She said: "Sadly his first son passed away at only seven weeks old. They were both devastated.
"Although his relationship with his ex-partner ended, they stayed in close contact for their (second) son."
Mr Summers' family had raised the alarm when he failed to keep the close contact he had maintained through texts and phone calls.
"Whatever he'd done, he didn't deserve the horrific and callous death he was confronted with.
She said: "Pete will be sadly missed and always remembered by the family who were there for him when he needed them most."
Police are asking visitors and residents at Squires Gate to cast their minds back over the last few weeks to recall anything suspicious in the area, particularly at the flat where Mr Summers was staying.
Detective Chief Inspector Ian Grant said: "There may be people with vital information.
"I can assure these people that they can come forward in complete confidence."
