FresnoBee.com: Local: Dave Hawk to stand trial in murder
Larry Crouch, a Kings County deputy district attorney, said the stolen license plate on the van led investigators to believe the crime was planned; that narrowed their focus to people who knew Debbie Hawk.
Crouch contends Hawk murdered his ex-wife "to cover up the financial crime."
The special allegation of financial gain makes the case potentially a capital offense, but prosecutors have not decided whether they will seek the death penalty.
In his argument Friday, Crouch said he believes Hawk planned to use an electronic stun gun purchased in May 2006 to disable Debbie Hawk, take her from her home, kill her and dispose of her body.
Police later found a stun gun during one of several searches of Hawk's home.
"I believe it was his intention to have her missing without any evidence where she went missing from," Crouch said, "and to have her car found in the possession of criminals in the Fresno area ... and therefore he would not be a suspect."
When the stun gun malfunctioned, Crouch said, Hawk "had to use alternative means to secure her, which led to blood being deposited in the house."
Crouch acknowledged his case is circumstantial -- there are no eyewitnesses, DNA, fingerprints, a murder weapon or even the victim's remains to connect Hawk to the crime.
"There's no physical evidence, but that doesn't mean I can't prosecute," he said. "It's fairly unusual [to not have a body], but that's not a concern to us proving our case."
