The love affair between Goofy Medic and Jenny 
Dyke had become common knowledge. Thus, when Jenny 
Dyke heard Goofy Medic had been killed, she pulled 
a knife on her husband, Rob, because she suspected him 
of the murder. But the Dykes' account of what happened --
 that they got separated due to poor visibility, and 
searched for each other without success-- is true. Rob 
didn't stay by the wreck, which is why he ended up so far 
downcurrent. 
     Like Rob Dyke, Erika Medic was aware of the 
affair between Jenny Dyke and her husband. Erika feared 
the affair would destroy the partnership and wreck her 
dream of owning her own dive shop. Erika planned to kill 
Goofy in a way that would look like an accident: she would 
cut his air hose, then once he was dead, she would entangle 
it on a sharp piece of metal in the wreck. This would 
preserve the partnership -- and give her exclusive control 
of the Sausalito dive shop. 
     While diving at the wreck, Erika Medic unsheathed her 
dive knife and sliced the air hose of her husband, Goofy. 
When he realized what had happened, he grappled with her, 
scratching her cheek and knocking her air hose free. But 
when he seized her weight belt, and it came loose, Erika shot 
up and away toward the surface-- a natural reaction which in 
this case proved fatal. 
     The weight belt in Goofy's lap is Erika's. She lost it 
before she surfaced, which meant Cory had to use the anchor 
line to pull her underwater for his rescue attempt. And the 
only reasonable explanation for Erika's missing knife is that 
she had it in her hand, and dropped it in panic during her 
rapid ascent. 
     Cory's attempt to repressurize Erika was exceedingly 
ill-advised, but it was not malicious. It is a common mistake 
committed by inexperienced divers. More experienced divers 
know that "the bends" are rarely fatal, and are easily cured 
in a decompression chamber on land.
