A Kailua man who allegedly tried to kill his girlfriend after drowning his dog in a bathtub was indicted Wednesday by an Oahu grand jury.

Harry Martin Lewis, 40, is facing charges of second-degree attempted murder, first-degree cruelty to animals and second-degree terroristic threatening. A bench warrant was issued for his arrest, with bail set at $1 million.

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

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

An argument ensued between the couple and Lewis then attempted to drown the woman, 42, in the bathtub and threatened several witnesses who live in the same residence, police said.

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.

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

Lewis was arrested that night after being discharged from the hospital on charges of suspicion of attempted second-degree murder, first-degree cruelty to animals and first-degree terroristic threatening.

“He’s a super nice guy,” said David Todd, Lewis’ friend. “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.

Todd said the woman is Lewis’ longtime girlfriend.
