"People have priorities where the money should be spent, and a new mental hospital for people who have been committed is not one of them," said Riddle.

Riddle added the new hospital should not just be built for the people housed there, but for the people who work at the facility.

"The population that serves those clients have a very difficult job," said Riddle. "It is arguably the most dangerous place to work in the state of Missouri."

Fulton State Hospital employs nearly 1,200 people. According to data from the Office of Administration, that's about two percent of state employees.

And according to the Missouri Labor Department, state employees filed 810 workers' compensation claims in 2009. Fulton State Hospital employees filed 170 of those.

That means a facility that employees just two percent of the state's employees accounted for more than 20 percent of the state's workers' comp claims.

So far this year, that number is 13 percent.

Martin-Forman says a new facility needs to be considered, not only for the staff, but also for the clients.

"The clients in Biggs are considered 'maximum security clients' the circuit courts commit to us," said Marty Martin-Forman, the chief operating officer at Fulton State Hospital. "They have to have committed a certain level of crime to be in Biggs. They've had to have committed a high level of crime to be in Biggs."

Rep. Riddle says Missouri law doesn't allow the state to set money aside each year until it saves up enough to build a new facility.

"It's going to require a tax increase or a bond, and people don't want to do that," she said. "But at some point, we can't kick the can down the road. We have individuals who work there having their lives destroyed by working there."   

Martin-Forman has been working at the facility for more than three decades. The reason she stays, she says, is because of the work the facility and its employees do.

"This hospital is amazing, what it is able to do in terms of treatment and to help individuals recover from mental illness," she said. "Despite the buildings and the physical campus, the treatment technologies here are incredibly good."

Since word of this story first began circulating, ABC 17 News has received numerous phone calls and emails from people associated with the Fulton State Hospital.

That includes a letter from the former Missouri Director of Public Safety, Charles Jackson. He said as director, he was responsible for a number of agencies, like the Missouri State Highway Patrol, Water Patrol and Capitol Police, yet no employees with those agencies compare to Fulton State Hospital workers.

"These agencies all were engaged in high risk duties, yet their combined rate of workers' comp didn't come close to the state hospital," Jackson wrote.
