It happened around 4:30 a.m. in the 1000 block of Cypress Station.
Deputies were called to the complex for a report of shots fired and found a man in the parking lot who'd been shot, according to Harris County Sheriff's sergeant Ben Beall.
As they were working to secure the area, deputies found the body of man who'd also been shot, Beall said. It appeared the man had tried to get away from the shooting before collapsing.
Eight to ten shots were fired during the violence and at least four vehicles were damaged by gunfire. At least one apartment unit's sliding glass door was also destroyed in the shootout.
Deputies believe at least one other person was involved, but there was no word on a description or what led to the shooting.
