Authorities had been focused on a portion of Exploration Green, just off Reseda, for hours.
A large space had been blocked off by crime scene tape, after hearing possible bodies were dumped in the area.
Around 8 a.m. Thursday, investigators returned with shovels and started digging.
They confirmed a couple hours later that no bodies were found.
This was believed to be gang-related, with the HPD Gangs Task Force taking part in the investigation.
Authorities say they don't plan to return to the scene.
Officials stress there is no immediate danger to the public.
