The brother of a woman found shot dead in her home has appealed directly to his father to turn himself in.
Colt Rodgers said the family has been "devastated"
Newly-wed Chanel Taylor, 23, was found with head injuries at a house in Huthwaite, Nottinghamshire, on 30 July.
Her father Terence Rodgers, 55, who has not been seen since, was officially named by police as the prime suspect.
At a press conference on Wednesday, Mrs Taylor's brother Colt Rodgers, appealed to him to contact police and let them "make sense of this nightmare."
He said: "Over the past few days our lives have been turned upside down.
"Chanel's death has left so many unanswered questions.
"We need your help to make sense of this nightmare. I am trying to be strong, especially for Mum, but we are all devastated.
"We've always been close, it was only the other week we were all together sharing
Chanel's big day."
Mrs Taylor had been married for just seven weeks.
Her husband, Lee, discovered her body at the terraced house on New Street at about 1300 BST on Friday.
Mr Rodgers' sister, Jean Winfield, said she thought her brother had been heading for a breakdown.
"Terry's my brother, he needs help."
She added she did not believe her brother was "in his proper state of mind".
Chanel Taylor lived at the house with her father
Mr Rodgers' red Peugeot 106 car was found just hours later, abandoned in Victoria Street in Hucknall - about seven miles from the murder scene.
Det Ch Insp Paul Cottee of Nottinghamshire Police: "We are working on the basis that Terry Rodgers, the father of Chanel, was in the house when the husband, Lee, left for work that morning and as such Terry Rodgers is now the main suspect in this murder investigation."
He said the motive for the shooting was still a mystery, since all the information at this time seemed to show Chanel and Terry Rodgers had a good relationship.
Mr Cottee added: "I'd like to give a message to anyone helping Terry, or sheltering him in any way.
"You are committing an offence, you will be arrested, you will be prosecuted."
Police are following up two sightings of Mr Rodgers walking along a road in Hucknall the day after Chanel's death.
The murder weapon, a shotgun, has not been found by police, who have concentrated their search for Mr Rodgers in the Nottinghamshire and Derbyshire areas.
Neighbours said they heard a row on the previous evening, followed by loud bangs, which were dismissed as coming from DIY.
Mr Rodgers is described as white, 5ft 10ins and stocky, with a shaved head.
He has a tattoo of a flower on his right forearm and a dagger and the name "Christine" on his left forearm.
