The parents of a boy killed by a driver who was high on drink and drugs have collected thousands of signatures on a petition to the Scottish Parliament.
Andrew Sneddon, whose son Ross was killed by Dean Martin
Ross Sneddon, aged five, was killed when Dean Martin, 23, lost control of a stolen car and struck him and two others on a Glenrothes street.
A mother and her daughter also died. Martin was sentenced to 11 years.
The petition, organised by Andrew and Michelle Sneddon, calls for life sentences for such offences.
Anne Martin, 39, her eight-year-old daughter Ashley and Ross all died following the incident, which occurred on Sunday 15 February in Minto Crescent, Glenrothes.
Martin subsequently admitted culpable homicide.
Family 'let down'
Mr Sneddon said at the time that his family had been "let down" by the justice system.
Initially, petition forms were made available in shops in the Glenrothes area.
The Sneddons want to highlight the issue nationally and they, along with Anne and Ashley's relatives, plan to put their case to the parliament's public petitions committee and to the UK Government.
Mr Sneddon said that many other people in similar positions felt the same injustice and that the laws involved had to be amended.
