THE father of a mum and her five-year-old son who were killed in an arson attack in Clacton will today renew an appeal for information.

It is 10 years on Sunday since Jean Trigg and her son Anthony died at a blaze in Church Crescent.

No-one has been bought to justice.

Jean's father, Les Trigg, who lives in Bolton, Lancashire, is set to speak at a press conference at Clacton Police Station.

Det Supt Kevin Macey, head of Essex Polcie's major crime review team, will also make an appeal.

Detectives hope the anniversary appeal will lead to new information coming to light.

A police spokesman said: “It is the 10th anniversary of the death of Jean and Anthony Trigg who died in the early hours of July 27, 1998 after a house in Church Crescent was deliberately set alight.

“Although two arrests were made in 1998 and 2004, no-one has been charged with the murder.

“Les Trigg is coming down to Clacton to make an appeal for information and talking to the media.

“Head of the major crime review team, Kevin Macey, will also be renewing the appeal.

“We feel there's somebody out there who knows who killed Jean and Anthony and hope after all this time someone's conscience is is saying it's time to say something.”

Ten years ago, police launched a double murder hunt centring on Clacton and the Bolton area from where Miss Trigg and her sons, Anthony and 14-month-old Callum had moved five weeks earlier.

They were staying with Christine Wroe while they looked for permanent accommodation.

The emergency services were called to the blazing house at about 4.30am.

Anthony Trigg was rescued but attempts to resuscitate him failed and he was confirmed dead at Colchester General Hospital. He died from inhalation of fire fumes.

His mother Jean, 27, died five days later at the hospital of multiple organ failure and inhalation of fumes.

Her other son Callum, who was four months old at the time of the blaze, was also rescued from the house and rescucitated by firefighter Paul Nash.

Christine Rowe, 36, was in intensive care for three weeks but made a miraculous recovery from her injuries.

Her daughter, Vicky, 11, also spent time in hospital but Craig Barton, 15, and Mark - Mrs Rowe's sons from a previous marriage - were out before emergency services arrived.

A 16-year-old boy was quizzed by police three months after the incident but was released without charge.

An inquest in December 1998 recorded a verdict of unlawful killing.

Forensic scientists said petrol had been used to start the blaze.

A 23-year-old man was arrested four years ago but was released without being charged.
