Hundreds of mourners attended the funeral Mass at Sacred Heart Church in Waterford, where four coffins, two white and two light brown, stood at the top of the church as a family photograph sat beside them with four white candles.
Gardaí believe the attack on the family's house in the Birchwood estate was linked to drug debt intimidation. Philip English's son told Irish broadcaster RTÉ that the family were targeted over someone else's drug debt. On Saturday, two people appeared in court charged in connection with the attack.
Addressing the congregation, Philip's cousin Raymond Power made a direct appeal to young people.
"Please walk away from drugs," he said. "Please ask for help when it comes to addiction. Please ask for help if you're being led down a bad path. Please choose a life, choose hope and please, most certainly, choose a future."
The Mass was led by parish priest Fr Gerry Chestnutt, with aides-de-camp for the Irish President, Taoiseach Micheál Martin and Tánaiste Simon Harris among those attending. Local TD and junior minister John Cummins and Sinn Féin leader Mary Lou McDonald also attended.
Fr Chestnutt said the community was "heartbroken" and described the four deceased as "the salt of the earth." "Last Tuesday morning, an act of total evil left a family and community devastated and heartbroken," he told mourners, saying "forces of darkness" had taken four innocent lives.
Philip was remembered as "funny, loveable, sensible and caring," Kim as "vocal," "feisty" and "a most loving, kind and caring person." Callum was remembered for his "mischievous smile" and Jayden as a "force of love" whose energy "bounded into the world." Gifts brought to the altar included a Minecraft t-shirt and toys for Jayden, a GAA club jersey for Callum, a Liverpool jersey and a Carlsberg beer can for Philip, and a bouquet of lilies for Kim.
The four were buried in Kilbarry Cemetery after the service.
