U.S. Postal Service worker dead in Florida after attack by multiple dogs

A U.S. Postal Service worker is dead in Florida after a group of dogs inflicted her with fatal injuries, local law enforcement said Wednesday. 

Pamela Rock "died Monday evening at around 7:30 p.m.," the Putnam County Sheriff's Office said in a Wednesday statement.

Witnesses to the attack "heard a woman scream for help and when they went outside they saw [Rock] on the ground with five dogs attacking," the sheriff's office said in the statement.

"Witnesses said several neighbors rushed to help by attempting to pull the dogs off and one neighbor shot a rifle into the ground to scare the animals," the statement continues. Responding deputies provided first aid before Rock was transported to a local hospital; she "remained in critical condition until her death," the sheriff's office said. 

The office said that local authorities have been called about the dogs in the past. It is unclear if charges are pending against the owner of the dogs. 

"At this time we are unable to release details as it is part of our current investigation," the statement said.
