An Oahu grand jury has indicted a 40-year-old Kailua man after he allegedly tried to kill his 42-year-old girlfriend and drowned his dog in a bathtub at his home.

The jury indicted Harry Martin Lewis today with second-degree attempted murder and first-degree cruelty to animals and second-degree terroristic threatening. A bench warrant has been issued for his arrest. Bail is set at $1 million.

The indictment comes after Lewis was released Tuesday night after posting $250,000 bail, police said. Prosecutors had charged him Tuesday afternoon for attempted murder and animal cruelty.

“It’s shocking,” said his friend David Todd, upon hearing the news of his arrest.

“He’s a super nice guy,” Todd said of Lewis, known as “Marty” to friends. “I’ve known him for about five years. He’s always laughing and smiling. When other people are stressed out, he’s even and calm-headed. Super-intelligent guy.”

Todd said he has worked with Lewis, an electrical engineer, on different projects, including some power distribution projects for the state, and he has always been reliable.

Todd said the woman is Lewis’ longtime girlfriend.

At about 8:15 p.m. Sunday, police said Lewis allegedly drowned his dog in a bathtub at his home at 458 Oneawa St.

An argument ensued between the couple. Police said Lewis attempted to drown her in the bathtub and threatened several witnesses who live in the same residence.

Emergency Medical Services arrived shortly after and transported him to Castle Medical Center. EMS spokeswoman Shayne Enright said Lewis was combative and his mental state appeared “altered” when paramedics arrived.

Paramedics treated him and transported Lewis to the hospital.

After he was discharged, police arrested Lewis at the hospital that night on suspicion of attempted second-degree murder, first-degree cruelty to animals and first-degree terroristic threatening.

Police contacted the Hawaiian Humane Society, which sent workers to recover the dog.
