The mother of a murdered teenager says she is "sickened, disgusted and a little bit scared" following a fatal stabbing in Clacton.
Caroline Shearer's son Jay Whiston, 17, was killed at a house party in Colchester in 2012.
She set up the charity Only Cowards Carry following his death to try to reduce knife crime and has a shop in Clacton just a couple of roads from the scene of the killing on Monday.
A man in his 50s was stabbed close to Pier Avenue. A 21-year-old man has been arrested on suspicion of murder.
Ms Shearer said police had still not been given strong enough powers or deterrents to stop people carrying weapons.
