Two unsolved crimes are to appear on Crimewatch in a bid to catch the offenders.
The first national appeal will focus on the death of Margaret Briers, a great-grandmother attacked in her own home.
She was left for a dead by a man posing as a police officer.
He threw her to the floor and broke her hip and then stole £16.
Ther
e have been few leads since the attack on March 30, and all proved fruitless.
The 82-year-old was found the next day by her daughter at her home on Calbeck Grove, Carr Mill, near Billinge.
She was taken to Whiston Hospital but died less than a week later on April 5.
The television programme will broadcast a reconstruction of the attack and will feature an interview with her daughter, Pauline Windsor.
She said: "It has destroyed our lives and the way our mum died will never leave us.
"The attack was cold, callous and despicable and it sickens me.
"Her great-grandchildren always ask after nana Peggy and we have to tell them that she is no longer with us and explain that a bad man attacked her.
"Someone must know something and we beg them to come forward, we will make sure justice is done."
The second appeal is about a series of attacks on a family in Garswood.
Mark and Ann Purnell run a taxi firm from their house on Hamilton Road and within one week their cabs were petrol bombed and a brick thrown through their windows.
The attacks, in October last year, were left them scared for their lives.
Their two young twin boys struggle to sleep and their parents lost money because of the impact on their business.
Ann said: "We are desperate that the offender or the offenders are caught.
"It has taken so long to get an appeal out.
"There is a CCTV image of a young man the police would like to speak to in regards to the incidents, which will be shown on Crimewatch.
"Someone must know who committed these vile attacks against our family."
Det Insp Chris Sephton said: "These crimes have had a terrible effect on the victims and their families and we are putting them out on Crimewatch in the hope to get fresh leads.
"Anyone with information should contact St Helens CID on 0151 7096010 or Crimestoppers on 0800 555111."
Crimewatch is on Monday at 9pm.
