The Irish Gardai confirmed that the human limbs found dumped in a sports bag on an estate are those of 17-year-old Keane Mulready-Woods who went missing from home.
On Wednesday morning, more body parts were found inside a burning car .
It is believed he was abducted and taken to a house in the town where he was murdered and his body dismembered.
The Irish Mirror reports he may have met up with two men he knew in the hours before he was butchered.
Yesterday an intensive forensic examination was carried out at a house in the Rathmullen Park area of the town where it is believed the teen was brought before he met his savage death.
Senior detectives at Drogheda Garda station last night confirmed the remains discovered on a road in Coolock, Dublin, on Monday night are those of the teenager who has an address at Beechwood Drive in Drogheda.
Gardai also said the murder is related to the ongoing feud between two Drogheda criminal gangs which has so far claimed three lives.
Investigators have no explanation as to why the teen’s body was cut up and left at different locations,
Deputy Garda Commissioner, John Twomey said the force is determined to bring those behind “this shocking crime” to justice. He added: “The level of violence is shocking.
“This is a brutal and savage attack on a child and is completely unacceptable in any normal democratic society.
“It is important to remember that Keane was a child, a young boy, trying to find his way in life, he has now lost his life and his family.”
Appealing to the public for information Commissioner Twomey said at the time, Keane was wearing a navy Hugo Boss tracksuit, black Hugo Boss runners (brown sole, black laces), red/orange Canada Goose jacket and a Gucci baseball cap.
Gardai are still searching for his clothes are understood to have been hunting for them in Drogheda yesterday.
Incident rooms have been established at Drogheda, Coolock and Mountjoy Garda station with the investigation being coordinated from the Co Louth town.
A family liaison officer remains in close contact with Keane’s family.
Gardai have appealed to the public for information from anyone who has knowledge of the teen’s movements from when he was last seen at 6pm in the vicinity of Dominic’s Bridge Drogheda on Sunday.
The Garda press conference came after the shocking discovery of more human remains in a burnt-out car in North Dublin in the early hours of yesterday.
Body parts were discovered in the torched vehicle in Trinity Terrace, a laneway off Clonliffe Avenue in the shadow of Croke Park.
Residents alerted emergency services when the burning vehicle was spotted at 1am.
A unit of the fire brigade put out the blaze and then made the shocking discovery in the smoking shell of the car.
It is suspected those partial remains are from the missing head and torso of tragic Keane whose dismembered limbs were thrown from a car 7km away in Coolock on Monday night.
The teenager is suspected of carrying out intimidation on behalf of one of the mobs and has been linked to firebomb attacks on homes.
He was warned his life was in danger and had been threatened in a chilling social media video that he would be abducted and chopped up.
Detectives believe the chief suspect for the savage killing is a psychotic Dublin criminal recently freed from custody.
A source said: “Even by the bloody standards of gangland there are not many people capable of something like this, but this guy is definitely one.”
Yesterday morning residents around Clonliffe Road were shocked to wake to reports that body parts were dumped in the burning car near their homes.
One resident said: “We had seen the orange glow and rang the fire brigade, but then when I saw the gardai had the lane closed off this morning I thought it must be something more than joyriders. Now that I hear what has been found it is shocking, absolutely shocking.”
Relatives last night paid tribute to the tragic teen.
Courtney Mulready posted: “You are so special in my life that I know no other person will be able to take your place my brother.”
Kelly Mulready said: “Fly high cuz. You were one of a kind! The best scrambler rider in Drogheda! Love you so much.”
