There are fresh questions coming out about the safety of taser guns. This after a man dies in Rockford police custody, after officers tase him multiple times.

Jane Imes is planning to buy a new fence.
"Cover the whole back, attach it to the garage and then go straight across here where it's impossible hopefully that nobody can get into my back yard."
Tuesday night Rockford police swarmed Imes' yard searching for a man seen running through the neighborhood.
"I was just nervous," says Imes.

The suspect was 29-year old Ernest Graves. Police were chasing him after a domestic disturbance at 1321 16th street.
Rockford Police Chief Chet Epperson says Graves resisted arrest and threatened to hit the officers chasing him down. Epperson says that's why officers pulled out their tasers.
One officer missed hitting Graves, but another, Officer Brian Prine tased Graves three times.
Once taken into custody, Graves complained of breathing difficulty and was taken to SwedishAmerican hospital, where he died.
Chief Epperson says officers are authorized to use tasers in any way they deem necessary.
"Officer Prine, Officer Kuhls deployed their equipment that they have to take care of an active resister, if that's once, twice, three times, five times, as many times as possible to take care of the subject," says Epperson.

But despite her overnight scare, Imes isn't sure she agrees with the level of force police used.
"I look at it like maybe it was a little excessive, but if someone's out of control too, the officer's got to protect themselves too," says Imes.

Tasers are not considered a use of deadly force. So the officers are unlikely to face a disciplinary investigation.
In this case, Winnebago County Coroner Sue Fiduccia does not know the exact cause of Graves' death, but she says the forensic pathologist does not believe he died as a result of being tased. Graves did have cocaine, marijuana and alcohol in his system.

23 Newa was unable to contact any members of Graves' family. Epperson says he's open to meeting with any family members who have concerns about the case.
The department is reviewing its taser procedures, though Epperson does not believe there was any wrong-doing. Epperson adds the case is a reminder that when an officer asks you to stop, you better stop.

Rockford police bought 50 tasers last year as another tool to ensure officer sagety. They can deliver a 50-thousand volt jolt, that momentarily incapacitates the suspect.
Again they are not considered lethal, but more than 100 people since 1999 have died in taser-related incidents. Fiduccia said Tuesday drugs can change the effect tasers have on a person. There's an ongoing debate over whether its the drugs or the taser that kills the person.

Anyone with information about this case is asked to call Rockford police at 815-987-5824, or Rockford-area Crimestoppers.
