Taser International Inc. (TASR) said on Friday an Arizona court dismissed a wrongful death and product liability lawsuit against the stun gun maker.

The ruling, which marks the third wrongful death suit against Taser to be dismissed in the last month, sent the company's shares soaring. Taser shares rose 8.53 percent to $9.16 on Nasdaq .

In the latest legal action, Taser said the Superior Court of the State of Arizona (search) in the County of Maricopa ordered a suit against Taser to be dismissed with prejudice, meaning the plaintiff will not be able to refile the suit.

The suit had charged Taser with liability for wrongful death, negligent infliction of emotional distress and product liability.

Taser has faced a series of similar lawsuits from families of people who have died after being shot with one of the company's weapons, which disable victims with a 50,000 volt shock, but none has been successful.

Human rights group Amnesty International (search) has logged more than 100 Taser-related deaths since 2001. Taser says its "non-lethal" weapons actually save lives when used by police officers as an alternative to guns.
