The man who invented the Taser has died.
Jack Cover was the inventor of the stun gun that is now used by thousands of police agencies as a better way to subdue suspects.
According to the company that now makes the Taser, Cover died of pneumonia last weekend. He was 88.
The Taser fires darts attached to wires that deliver electric shocks, temporarily subduing aggressive suspects.
Even though it's become a common tool for police, it's still controversial because it has been linked to a number of deaths.
The company says Cover began developing the Taser as a non-lethal weapon to be used against the hijackings and riots that were happening in the 1960s.
