Pc David Phillips' widow broke down in tears as his sisters and best friend paid tribute to the "man they adored".
His sister, Hannah Whieldon, described his death as a "sickening, gut-wrenching mess" and said Pc Phillips was "the glue that bound all the families we represent here together".
Six people have been arrested in connection with the 34-year-old father-of-two's death after he was mown down by a stolen pick-up truck in Merseyside in the early hours of Monday.
At a press conference on Wednesday, his wife Jen dabbed tears from her eyes and was comforted by those gathered around her.
Her sister-in-law Mrs Whieldon said just hours before his final fatal shift he was with his wife filming their girls "beaming" with smiles, singing and dancing.
"Now he will never see his precious girls age even a minute more," said Mrs Whieldon.
"They'll never be young women to him now. He'll never get to raise his eyebrow disapprovingly at any future boyfriends.
"He'll never walk them down the aisle, glowing with the pride he felt every day for his Abi and Sophie.
"All we have are hollow memories that can't be held or hugged or kissed and a pain that won't stop."
Another of Pc Phillips' sisters, Kate, said "he meant so much to so many people".
She said: "Though we are broken and a piece of us will always be missing, we will start to mend together. Always together, with our hero in our hearts."
Pc Phillips' childhood friend Dave George, who was the best man at his wedding in 2011, described him as a "first class" police officer, father, husband, son, brother and friend.
"He was never happier than when talking about his wife, children and family," said Mr George.
He added that Pc Phillips was "well aware" of the risks he faced in his job but "never complained".
Mrs Whieldon said "no two people were ever more meant for each other" than Pc Phillips and his wife.
She read out a poem her brother wrote and gave to his wife for their fourth wedding anniversary.
