Gardaí have begun a murder investigation having received the preliminary results of post mortem examinations which have taken place on the remains of the two men found in a burned out car late last night in Co Louth.

The remains of the two people, still unidentified, have been brought from the scene at Ravensdale Forest near the border to Our Lady of Lourdes Hospital in Drogheda.

Deputy State Pathologist, Dr Kahlid Jabbar, conducted a preliminary post mortem examination at Our Lady of Lourdes Hospital in Drogheda.

He concluded that the two men had been shot dead.

The Ravensdale Forest is located just off the M1 motorway near the border.

A passing motorist saw a car on fire and raised the alarm just before 11pm last night.

Within a few minutes, the fire service had arrived at the scene to extinguish what they initially believed to be just a car fire.

Both bodies were in the front seats of the car and it appeared the passenger may have been slumped over onto the driver's side.

The door on the driver's side was also opened slightly.

The area was been sealed off throughout the day as garda forensic experts searched the vicinity of the charred car and surrounding forest.

As part of their investigation, gardai have asked for the public's assistance.

A car was found abandoned near Jonesboro today and is being examined to see if it is linked to the killings.

Gardai believe the two people who died were men in their 20s and from Dublin and that their deaths are related to a gangland drugs feud.

The scene will remain sealed off overnight and a forensic search will resume tomorrow.

A full post mortem will take place tomorrow morning.
