A woman at the complex who first called police said she was worried that a friend who was coming over was going to hurt himself or someone else.
When HPD officers got there, they saw the 36-year-old man had a gun and was walking toward them. Police say he fired once into the ground, and then started shooting at the police.
A pair of HPD officers took cover and then opened fire, according to Executive Assistant Chief Matt Slinkard.
"It came in originally as what appears to be at best a disturbance, but don't know if there were any mental health issues involved," Slinkard said.
