Judgment Prey by John Sandford

Alex Sand was spending the evening at home playing basketball with his two young sons when all three were shot in cold blood. A wealthy federal judge, there’s no short list of people who could have a vendetta against Sands, but the gruesome murders, especially that of his children, turn their St. Paul community on its head. Sand was on the verge of a major donation to a local housing charity, Heart/Twin Cities, and with the money in limbo, eyes suddenly turn to his grieving widow, Margaret Cooper, to see what she might do with the money. Margaret, distraught over the death of her family, struggles to move forward, and can’t imagine how or why anyone would target her husband.
