Blake spoke Thursday at an event to promote this summer's New Haven Open. He told reporters that his thoughts and prayers are with the victims' extended family, and he hopes police will keep him updated on the investigation.
Police say the man who rented the home, Darrin Campbell, shot his wife, Kimberly, 19-year-old son and teenage daughter each in the head with a .40-caliber handgun May 7 before setting the 6,000-square-foot house on fire and shooting himself in the head.
Blake said his only contact with Darrin Campbell was "a few emails for the lease agreement." He says he never met any of the Campbells face-to-face.
