Officials said the shooting happened at about 1 a.m. at the old Greenspoint Mall parking lot in the 200 block of Greens Road.
At one point, HPD says, gunshots were fired near the area, and one person, who police said was in his late teens, was hit and pronounced dead at the scene.
Authorities said the victim was at the car meet-up with a friend.

It is unclear what led to shots being fired, officials said.
HPD says there are no suspect descriptions, as those who were participating fled the area after hearing the gunshots. Lt. J.P. Horelica said there could be a possibility that the cars that were there were also hit with bullets, and an investigator later confirmed a truck had at least 5 or 6 bullet holes in it.
Officials say multiple people were shooting guns, but it is not yet known if multiple people fired them.
The parking lot is reportedly a regular Sunday meeting spot for meet-ups and "reckless driving," HPD said. Horelica said it is not uncommon for officers to be dispatched to that area to break it up.
A homicide detective tells ABC13 that the event, called Slab Sunday, usually draws over 100 people and takes place at various locations across the city.

"Constantly, on Sundays, North Belt patrol dispatches to this parking lot regarding meetups and reckless driving. They come out here regularly on Sundays and run everybody off, and end up making arrests when they can," Horelica said.
HPD is urging anyone with information regarding the shooting to come forward and contact law enforcement.
Authorities are asking local businesses for surveillance footage in hopes that it will show cars leaving.
