The Jacksonville Fire and Rescue Department is expected to issue written reprimands to several firefighter men and women after an internal investigation into their behavior during a fundraiser earlier this month found they violated policy, according to JFRD spokesman.

Racy photos of the firefighters were taken at Whiskey River at the St. Johns Town Center during a fundraising event for the family of Jason Bishop, a firefighter who died in a tree-cutting accident.

The website 904HappyHour.com posted the pictures of men and women in their bunker gear acting provocatively.

The Fire Department opened an investigation last week to determine if any policies were violated. Spokesman Tom Francis said Tuesday the investigation was over and written reprimands are expected.

A district chief and a lieutenant were present at the event, but Francis couldn't say who was going to be disciplined.

He said the policy violations likely stem from the men and women wearing their bunker gear to an event without the Fire Chief's permission.

"I feel like the members that were there were doing a great thing for the Bishop family, trying to raise money for his kids and his wife," said Randy Wyse, president of the fire union.

Wyse said his men and women can appeal their punishment. He said it's too early at this point to know if that will happen.

"To say what's appropriate and what's inappropriate, that's what concerns me, what we call the 'Moral Police,'" Wyse said. "Where they're off duty, they're doing their own thing, and to say what they did or people's perception of the pictures come into the punishment, I got a real problem with that."

The firefighters who receive written reprimands have 10 days to appeal.

Francis couldn't say how many of the employees will receive that letter in their file.
