Hundreds of young people formed a wave of black and red Wednesday afternoon along the grassy knoll overlooking a growing memorial on Kaimalie Street in Ewa Beach that had been put up for Kawehi Adkins-Kupukaa, who died after a head-on crash Tuesday afternoon.

Flowers, food, containers of alcoholic and nonalcoholic beverages, candles, posters, photos and letters were among the items left in memory of the 14-year-old Campbell High School sophomore. The black is one of Campbell’s school colors, and friends said red was Adkins-Kupukaa’s favorite color.

Adkins-Kupukaa was the front-seat passenger in a GMC Envoy SUV driven by Brandon Harris, 16, who remained hospitalized in critical condition, according to friends. A source familiar with the situation said Harris is expected to survive.

Johnoven "John John" Lagon, 15, Adkins-Kupukaa’s boyfriend, was in the back seat and suffered serious injuries but was released from the hospital late Tuesday. A 41-year-old Ewa Beach woman, whose Porsche Cayenne SUV was struck by the Envoy, also was released from the hospital within 24 hours of the crash, sources said.

After striking the Porsche, the Envoy continued down Kaimalie and struck a parked minivan before hitting a tree.

Lagon visited the crash scene at least twice Wednesday and was greeted by a steady stream of hugs and handshakes from classmates and others.

He said he felt "heartbroken" and "shattered" by Adkins-Kupukaa’s death.

"It’s the worst feeling in the world," Lagon said, adding he wished he could do something to bring her back.

Lagon told reporters that Harris had consumed some beer but did not appear drunk.

Police said speed and alcohol appeared to be factors in the crash.

He said he and Adkins-Kupukaa were hungry and Harris took them to visit a manapua man near the campus. They were on their way back when the crash occurred, Lagon said.

Ikaika Kupukaa, 25, one of Adkins-Kupukaa’s four siblings, stayed near the Kaimalie Street memorial through most of Wednesday afternoon.

Kupukaa described Adkins-Kupukaa as "a happy-go-lucky girl" who loved life, surfing, softball and making people laugh.

Online, more than 10,000 Facebook subscribers "liked" a page set up in memory of Adkins-Kupukaa only a day after it was created by friend Ko‘Olina Cho, a Kapolei High junior.

Campbell counselors made themselves available to students through the school day Wednesday. During first period, students held an impromptu gathering.

But many tried to find resolution by going to the memorial.

Rebecca Save, a 17-year-old senior, knelt and quietly read a prayer she had written for Adkins-Kupukaa.

Save, who said she didn’t know Adkins-Kupukaa, said she felt compelled to offer the prayer because the death "impacted me a lot."

She added: "This is a lesson for everybody … be smart about the choices you make."
