The man came back again the next day, police said. Just before 8:30 that morning, he again fired at the apartments.
No one was injured in either incident.
Police are looking into whether the man was targeting a specific person, Channel 2 Action News reported. Several residents told the news station they were inside their homes when the bullets started flying.
Sharon Bryant said she was in her apartment with her grandchildren at the time. She told Channel 2 she grabbed them and hit the floor.
"It could have went right through me and my grandkids and stuff," Bryant said. "I was afraid.”
