Honolulu Police Department has opened a second-degree murder investigation after a 17-year-old boy died early this morning in Makaha Beach Park in an apparent shooting, which allegedly followed an argument with an unknown suspect.

Police said they responded about 12:30 a.m. to calls of multiple shots being fired at Makaha Beach, according to a daily bulletin from HPD’s Criminal Investigation Division (CID). Officers said upon arriving at the beach park that they found a male, who “had been shot and was laying unresponsive on the ground.”

Honolulu Emergency Medical Services arrived, but the victim was reportedly found “DOA” or dead on arrival, according to an EMS report filed at 1:11 a.m. today.

Officials from the Honolulu Fire Department were also on the scene. The victim’s identity was not immediately released.

Police reported in the CID daily bulletin that an investigation is underway, which has determined that an unknown suspect “was arguing with the victim prior to the shooting.”

“It appears that the victim knew the suspect and this was not a random act,” the bulletin added.

The suspect is described as a “local” mixed-race male approximately 15 to 17 years old, and about 5 feet four inches tall to 5 feet six inches tall. The suspect was wearing dark-colored clothing and was allegedly in possession of a firearm, according to a description given to police.

Police said they were told that the suspect fled in a white vehicle with another “local” mixed-race male.
