Parents' fresh appeal to catch son's killers

The parents of a young man shot dead at a caravan site near Stevenage in Hertfordshire have made a fresh appeal for help to catch his killers. 21 year old Thomas Ward was shot in the chest outside his home on Dyes Lane in April.

Since then police have been looking for his second cousin, 32 year old John Boy Ward - who's wanted on suspicion of conspiracy to murder. Olivia Paterson reports.
