According to investigators, the mail carrier was on her daily route in the 600 block of Northwest Sixth Street at around 1 p.m. when she spotted Holley in the second floor front window.
Witnesses later told investigators that Holley had been seen earlier in the day pointing the rifle at neighbors, according to the complaint.
After seeing the gun and leaving the package, the mail carrier quickly returned to her truck and drove away. She got about 20 feet from the home and heard a thud, investigators said. The thud turned into being a bullet to the back of the truck, investigators said shortly after the shooting. The mail carrier, who was not injured, immediately called 911.
Shortly after the shooting, Florida City police — with the help of Miami-Dade police — took Holley into custody.
