Stevenage caravan site shooting death cousin sought
The second cousin of a young father murdered in Hertfordshire is being sought for questioning by police.
John Boy Ward, 32, and his pregnant wife Joleen Josie, 21, from Hatfield, may have fled to Europe, according to police.
Thomas Ward, 21, was confronted by three masked men as he slept with his wife and his five-day-old daughter in a caravan in Stevenage.
John Boy Ward is wanted on suspicion of conspiracy to murder.
His wife is wanted on suspicion of assisting an offender, Hertfordshire Police said.
Detectives have appealed on BBC's Crimewatch for help to trace John Boy Ward and his wife Joleen Josie whose last known address was Clarkson Court, Hatfield.
When Thomas Ward came out of the caravan he lived in with his family at Dyes Lane near Stevenage on 23 April he was shot in the chest.
He was found unconscious in undergrowth nearby and died later that night in hospital.
Det Chief Insp Sharn Basra said: "We urgently need to trace both John Boy and Joleen.
"This is such a horrific crime and I would urge anyone who has any information on their whereabouts to contact us immediately.
"We believe the couple left the country in the days after the murder and may be in Europe.
"However, they do both have links to North London and I would appeal to anyone in the North London area who may have knowledge of their whereabouts to contact police."
Police are also looking for three vehicles which have been connected to the investigation - a white Audi, a white Volkswagen Golf and a black Mercedes C250.
DCI Basra said: "We have since recovered the white Audi but would appeal for anyone who saw this vehicle on the night of the murder, and any of the other vehicles mentioned since that evening to contact police."
