Hayakawa said police ignored other leads for possible suspects, noting that Tokuhara was a gambler and nearly $4000 ($6279) in cash was found next to his body in his office.
Thompson and his wife were high school sweethearts.
Tokuhara ruined the couple’s image of a perfect life and that’s why Thompson killed him, KHON-TV reported a prosecutor saying.
“He shot him not once, not twice, not three times, but four times to the face,” said Deputy Prosecuting Attorney Benjamin Rose.
Surveillance footage shows Thompson parked near Tokuhara’s office and walking in wearing a hat and sunglasses, police said. The hat fell on the street as Thompson was leaving, police said, and DNA testing showed it was likely worn by Thompson.
“Eric Thompson killed the man who slept with his wife,” Hawaii News Now reported Rose saying. “This is a story as old as time.”
The trial continued Thursday and the judge expects it to wrap up by the end of the month, KITV reported.
