Las Vegas leads the nation's cities in suspect deaths involving law enforcement use of Tasers, an Amnesty International study to be released today concludes.
The study found that between June 2001 and August 2008, seven people died after Tasers were used on them. The figure tops that for Phoenix, where five people died after Tasers were used on them, according to the study.
Dalia Hashad, director for the USA program for Amnesty International, said the nonprofit study indicates that more research has to be done to determine the safety of Tasers. At the very least, she said, police should not use Tasers in confrontations with suspects who do not have weapons.
Hashad said the fact that Las Vegas leads the nation with the most Taser deaths is a possible sign that Southern Nevada law enforcement is using the weapon negligently. A Taser delivers 50,000 volts of electricity to the target, which tenses muscles and incapacitates the body.
"Behaving erratically, not responding to police, talking back, these are not invitations to use a Taser," Hashad said.
The study said six of the seven deaths in Las Vegas followed Taser use by the Metropolitan Police Department. One death involved Taser use by the Nevada Highway Patrol.
Nationwide, 334 people died after they were shot with Tasers, the study said. California and Florida had the highest number of deaths among states, with 55 and 52 respectively.
Las Vegas police spokeswoman Barbara Morgan said her agency began using Tasers departmentwide in July 2004.
She said that although people have died after being shot with the weapon, the Clark County coroner never concluded that the use of a Taser was the cause of death.
"We have no deaths caused by Tasers," Morgan said. "Some of them were narcotics or heart problems."
The study asserted that in four of the Las Vegas deaths, Taser use was at least a contributing factor.
In 2004, three suspects died in a six-month period after Las Vegas police used Tasers on them. In one of those cases, a medical examiner did conclude that a Taser contributed to the suspect's death although it was not the primary cause. In three cases, the suspects had cocaine or PCP in their systems. In one case, the suspect on PCP was struck with a Taser seven times while handcuffed.
Hashad said one of the more egregious cases involving a Taser happened this year in Southern Nevada.
In early January, doctor Ryan Rich, 33, died after a Nevada Highway Patrol trooper fired a Taser at him. Authorities said Rich was fleeing from a trooper when he crashed his pickup into the center median on Interstate 15, near the Las Vegas Beltway. Moments earlier, he crashed his pickup into at least two other vehicles.
Rich then fought with the trooper and a motorist who had stopped to help. He tried to run into traffic as he was being subdued, police said.
Hashad said the trooper should never have used a Taser on an unarmed man who probably was disoriented after crashing his vehicle. "It's really an unfortunate example of how this weapon is used when really no weapon should be used at all," she said.
Trooper Kevin Honea, spokesman for the highway patrol, said Tasers are safe.
"We've used them hundreds of times without the same result," he said. "They are a very useful tool. They are classified as a less lethal option."
The trooper's actions were cleared when a coroner's inquest jury in April found that Rich's death was excusable.
A forensic pathologist determined the cause of the death was a seizure disorder with other conditions, including police "restraining procedures."
