From the Sun Sentinel.com:
ShareOn Jan. 8, Barker paid a friend $20 to drive him and Sam to the L-20 Canal east of Kings Highway, his affidavit states. Barker stepped out of the vehicle, struck the pit bull on the head several times with the tire iron and tossed him into the canal. The blows did not kill Sam, who swam out of the water and attempted to climb the embankment, according to the affidavit. Barker caught Sam and used a knife to stab him 26 times in his neck, the Sheriff's Office said.
