Just over a year ago Caroline Shearer's 17-year-old son, Jay Whiston, was stabbed to death at a house party in Colchester.
Since then she's launched a charity which aims to rid the streets of knife violence.
Today her 'Only Cowards Carry' charity launched a new schools programme, designed to educate children on the consequences of carrying knives.

A charity set up by the mother of murdered Essex teenager Jay Whiston has begun carrying out workshops warning about the dangers of knife crime.
Schools across North Essex, including Tendring Technology College, are signing up to the scheme run by 'Only Cowards Carry Weapons'.
Jay was stabbed to death at a house party in Colchester last September. He was 17 years old.
