Orange County, Florida - Another suspect subdued by a deputy's taser died Wednesday as the Justice Department investigates Orange County's use of tasers.

A man holding a squeegee was charging at cars on Orange Blossom Trail late Tuesday night. Deputies said they used the taser to calm him down, but he later died. All indications are the suspect was out of control.

The sheriff's office said 45-year-old Jose Amaro was running in and out of traffic on South Orange Blossom Trail at West Landstreet Road, lunged at deputies and ran from them. They said he was high on a mix of cocaine and alcohol. When you add a taser, the results can be deadly.

The sheriff's office said Deputy Andrew Reynolds used his taser on Amaro three times, because it wouldn't work on him. He either ran back out into traffic or charged toward the officer. They were told he had a hammer in his hand, but it turned out to be only a squeegee.

It was the fifth death in the seven years the sheriff's office has been using tasers. In all cases, the suspects were on drugs. But the sheriff's office said there's no way for deputies to evaluate that in the heat of the moment.

"When a situation turns violent, it's an immediate and dramatic turn of events and deputies don't have a lot of time," explained Jim Solomons, Orange County Sheriff's Office.

Less than 12 hours after having been shot with a taser three times, Amaro died Wednesday morning at Florida Hospital Kissimmee.

The sheriff's office says its taser use dropped in 2007 from 368 to 306, the same year the Department of Justice opened an investigation into its use of tasers. The investigation has not yet been completed.

"Is this a troubling thing to have happen in the middle of the ongoing investigation?" WFTV reporter Kathi Belich asked Solomons.

"I think troubling is inappropriate. You don't go out at night intending to take a life. It's unfortunate when it happens," he said.

The sheriff's office is investigating. Deputy Reynolds is on desk duty for a week.

The sheriff's office said the taser has prevented deputies from using their guns 100 times in the last year.
