Sally Kerr and son Richard appealed for information about the murder
A businessman shot dead in County Antrim earlier this week is believed to have been the victim of a robbery which resulted in murder, police have said.
Geoff Kerr, 60, was shot dead at his home in Templepatrick on Monday night.
The detective leading the investigation held a press conference about the murder on Thursday.
Mr Kerr's wife of 30 years, Sally, described him as "the rock which we all clung to" and appealed to anyone with information to come forward.
The financial adviser was shot dead outside his home in the old village area of Templepatrick, which is 10 miles north of Belfast.
His wife and one of his four sons were in the house when the shooting took place.
"I'm very proud of Geoff and what he achieved in life and for his sake I want these people found," Sally Kerr told a news conference.
"He had a huge heart, he was very compassionate, he always put people before himself."

"My husband was just the best person that I could have hoped to have as the partner in my life. My sons and I are just going through the worst possible experience that anyone could ever have."
Mr Kerr moved to Templepatrick about a year and a half ago.
He had lived and worked in the Ballymena area for many years, where he was also a member of a gun club.
