Alins Sumang, the 27-year-old accused of killing three pedestrians Monday evening in Kakaako, had a strong odor of alcohol on him and a half-empty bottle of Absolut Vodka on the floorboard of his Ford F-150 pickup at the time of the crash, police said.

He was belligerent, had slurred speech and cursed at Emergency Medical Services personnel when police arrested him at the scene, court documents said.

Sumang stood silently in a courtroom Thursday with his head down and his hands cuffed. He is charged with three counts of manslaughter in the deaths of Casimir Pokorny, 26, of Pennsylvania; Dr. William Travis Lau, 39, of Honolulu; and Reino Ikeda, 47, of Japan. If convicted, Sumang could spend 60 years or more behind bars.

One of the responding police officers at the crash scene “could smell a strong odor of an alcoholic beverage emitting from Sumang as he spoke from about 12 inches away.”

Before the deadly crash, Sumang had slammed into parked cars several blocks away and was being followed by a police vehicle as he sped down Ala Moana Boulevard, police said. He swung across three lanes of traffic to attempt a right turn onto Kamakee Street, running over a pedestrian island, leaving three dead and three injured, finally ramming into another pickup and critically injuring its driver, police said.

The reckless nature of Sumang’s actions led to his being charged with three Class A felonies, which carry a maximum sentence of 20 years each, police said.

Police took Sumang to Straub Medical Center in serious condition for injuries he sustained in the crash and released him from the hospital Wednesday. He is in custody at the Oahu Community Correctional Center with his bail set at $1 million.

Sumang has two prior convictions: one for felony terroristic threatening and a petty misdemeanor conviction for criminal property damage. In one case he was convicted of threatening a man with a knife in the parking garage of his Makiki apartment building.

As Sumang was facing a potentially lifelong sentence, the families, friends and co-workers of the victims were dealing with their shocking loss.

“We are heartbroken over this senseless tragedy, which has taken an excellent specialist physician away from the community,” said Lau’s colleagues at Pacific Anesthesia.

Lau was a “dedicated, talented cardiac anesthesiologist” who cared for the “very sickest patients,” they said. “We extend our sincerest condolences to Dr. Lau’s wife Melissa, as well as to his parents and family. Our hearts are with them in this time of grief.”

Lau, Pokorny and Ikeda were pronounced dead at the scene.

Pokorny’s friend Lianna McCurdy was taken to the hospital after she suffered serious injuries. McCurdy’s boyfriend and Pokorny’s girlfriend, who were with them at the time, were not injured.

Police said a 26-year-old female bicyclist was taken in critical condition to a hospital, and a 27-year-old male Biki bicyclist was treated and released.

Court documents indicated the man recalled being on the bike as he waited to cross the street with the 26-year-old woman, an acquaintance who was on a separate bicycle. The next thing he remembered was being inside an ambulance.

Biki, the bicycle rental company, said in a statement, “We have been in touch with the family of the male Biki customer injured Monday night while standing at the concrete traffic island with the other pedestrians. We have been informed that he was released from the hospital (Tuesday). Our thoughts and prayers are with the innocent bystanders killed or injured in this collision and their families.”
