The family, originally from Harsi Pind in Hoshiarpur, Punjab, was kidnapped at a business in Merced County, California, on Monday.
The suspect in the killing of an Indian-origin Sikh family, including an eight-month-old baby girl, had once worked for the family's trucking business and had a longstanding dispute with them that got 'pretty nasty' and culminated in an act of senseless killing, authorities and a relative said.
