Deleon is also being tried simultaneously for the murder of John Jarvi in 2003, whom he met in jail.
Prosecutors are seeking the death penalty.
Henderson was convicted for her role in the Hawkses’ murders last year and was sentenced to life without parole.
Prosecutors claim that through lies to Jarvi and the Hawkses, half-truths to select friends and the promise to his accomplices of making it rich, Deleon led four other people to help him kill Tom and Jackie Hawks. The two men who authorities say helped in the murder face trial next year.
Defense attorney Gary Pohlson has so far made minimal effort to rebut the prosecution’s case, telling the jury in his opening statement that Deleon is guilty.
Pohlson said his job is to persuade them to spare Deleon the death penalty. He’s doing that in part by shifting responsibility to Deleon’s ex-wife.
Henderson’s dad, Steven Henderson, testified that his daughter gave him money to buy cleaning materials they were going to use on the boat.
Later that day, he testified, he was bleaching the Hawkses’ boat while Skylar and Jennifer were below, rummaging through the couple’s things.
It was, as prosecutors claim, just another lie benefiting Deleon.
In forged military documents, Skylar Deleon claimed that he was part of a special forces unit that doesn’t exist outside of an Xbox video game, a staff sergeant in the Marine Corps testified.
In documents Deleon showed to friend Adam Rohrig to impress him, Deleon’s listed unit with the Marines was the “Yankee White” special forces unit, prosecutors said.
Staff Sgt. Shamar Underwood testified that among other things wrong with the document, the only “Yankee White” he could find was in a video game.
