Police are investigating recent business transactions made by adviser Geoff Kerr, who was shot dead at his home in Templepatrick, Northern Ireland on Monday evening.
According to the Belfast Telegraph, police and Kerr's family are 'baffled' as to who may have wished to murder him.
However, it is believed the inquiry has now turned to recent business dealings the financial adviser may have had.
The 60-year-old leaves behind his wife Sally and four children.
