Witnesses observed two vehicles racing on eastbound lanes of the H-1 freeway before the Middle Street tunnel before one of the drivers allegedly cut off the other motorist and fatally shot him in Kalihi Friday night.

Eddieson Reyes, 37, is being held at the Oahu Community Correctional Center in lieu of a $1 million bail on charges of second-degree murder in the shooting death of 19-year-old Triston O. Billimon.

Reyes is also charged with two counts of firearm offenses and one count of first-degree terroristic threatening.

The shooting occurred near the Kalihi-Palama Library at about 11 p.m. Friday.

Police responded to multiple calls of a gunshot heard on Kalihi Street and a male in a white vehicle traveling toward Kalihi Valley.

Police said Billimon was traveling on the eastbound lanes of the H-1 freeway in a silver BMW with his wife prior to the Likelike off-ramp when a white sedan cut them off.

According to court documents, Billimon’s wife told police the sedan then merged to the driver’s side of the BMW and allegedly pointed a gun toward Billimon.

The BMW came to an abrupt stop. Billimon’s wife then “suddenly heard a gunshot and then noticed that Billimon had been shot,” police said in court documents.

Billimon was taken to The Queen’s Medical Center where he died of a gunshot wound to the chest.

Police said the motive of the shooting remains unclear at this time.

“It doesn’t appear that they know each other,” said Lt. Deena Thoemmes of the Honolulu Police Department’s Homicide Detail of Billimon and Reyes.

According to court documents, a witness reported to police that Billimon was traveling on the eastbound lanes of the freeway toward the Middle Street tunnel when he observed two vehicles — a white Acura and silver BMW — racing. The two vehicles then took the Likelike off-ramp and suddenly stopped on Kalihi Street.

Police said the witness saw the Acura driver step out of the vehicle, run to the driver’s side of the BMW and fire a shot through the window. The suspect appeared to be holding a handgun at the time.

The alleged gunman then fled the scene in the Acura.

Another witness said he was driving in the area when he saw two vehicles stop at the top of the Kalihi off-ramp. As he drove by, he heard a gunshot and immediately called 911.

The witness followed a white vehicle that sped off from the scene. At some point, he saw the sedan pull over on Nalanieha Street and two males exit the car. He observed part of the license plate as “415.”

An officer responding to the shooting observed two males that matched the suspects’ descriptions walking on the pedestrian overpass on Nalanieha Street and Likelike Highway. As he made a U-turn to stop them, the officer lost sight of the pair.

Just before 11:30 p.m., police dispatch received a call from a man later identified as Reyes who reported his white four-door Acura with the Hawaii license plate number WBU 415 was stolen.

Police arrested Reyes early Saturday on suspicion of murder after a witness positively identified him as the suspect who allegedly shot Billimon.

Police noted the whereabouts of the Acura that’s registered to Reyes is still unknown.
