Paul Dhaliwal, 19, told the father of Carlos Sousa Jr., 17, who was killed, that the three yelled and waved at the tiger but insisted they never threw anything into its pen to provoke the cat, according to a search warrant affidavit obtained by the San Francisco Chronicle.
...Toxicology results for Dhaliwal showed that his blood alcohol level was 0.16 percent after the attack - twice the legal threshold for drunkenness - while his 24-year-old brother Kulbir Dhaliwal's blood alcohol level was 0.04 percent and Sousa's was 0.02 percent, according to Inspector Valerie Matthews, who prepared the affidavit.
