A 20-year-old Aiea man who was found bleeding near H-1 freeway’s Houghtailing Street offramp early Friday died from cuts and stab wounds caused by pieces of a glass louver that his killer had smashed on his head, said Keith Seto, deputy city prosecutor.

Jason Oliveros died at the scene shortly after a city ambulance crew arrived to assist him.

An Oahu grand jury returned an indictment today charging Vainuupo Tosoga with Oliveros’ murder.

Vainuupo, 21, of Kalihi, remains in custody unable to post $150,000 bail.

Seto said Tosoga got into an argument with Oliveros and then chased him across the freeway to Halona Street, where he punched Oliveros. He said Tosoga found a pile of glass louvers there and used one to strike Oliveros in the head, leaving him with a piece of broken glass in each hand.

“The defendant then used the shards of glass to stab and slash the victim causing him to bleed to death,” Seto said.

Honolulu police said one of its officers later saw Tosoga across the freeway with blood on his hands, leg and shoulder. They said Tosoga told them he chased Oliveros because Oliveros threw bottles at him and his cousins.
