JACKSONVILLE, Fla. -- Despite having a budget that has grown by $100 million in the past five years, Jacksonville's sheriff has asked the city for more money because most of the budgeted funds must be used for things he cannot control.

Sheriff John Rutherford recently asked the city for a big increase in JSO's budget, and he painted a bleak picture for Jacksonville's future if he doesn't get the requested funds.

"If we don't turn this thing around, we could be the next Detroit. That's what I am concerned about," Rutherford said.

He predicted a grim future for the sheriff's office while pushing for more money, more police and more jail guards.

In the past five years, the sheriff's budget has increased by more than $100 million. It has jumped from $215 million to $322 million, yet not a single new officer has been hired.

"No, we have not hired any new police positions. None. Not one," Rutherford told Channel 4.

The sheriff has replaced retired officers, but he has not increased the size of the force. The additional $107 million has been used for pension funds and overtime pay.

"I can't afford to leave those officers in one area because we are moving them all over. We are trying to stamp out fires now, instead of going in and taking over neighborhoods and holding them," Rutherford said.

On Thursday, a committee looking into Jacksonville crime problems questioned the sheriff about his spending practices.

The group found out that the sheriff has no control over nearly 80 percent of his budget -- $254 million -- because it goes to salaries and keeping inmates in jail. The sheriff has little control over 14 percent of his budget -- $45 million. The sheriff does have control over 7 percent of his budget -- $13 million -- for things like office supplies, travel and training.

As a result, Rutherford said they need more money to bring in 225 more police, 124 more guards and 84 new civilians.

The committee that's looked into the sheriff's spending said it agrees there is not much left to cut except at the jail.

"We understand that jail overcrowding leads to increase budget strains and demands on JSO, which means less officers on the street," said former U.S. Attorney Paul Perez.

The committee is expected to make some recommendations based on its findings. The mayor said he would follow through with what the committee suggests.
