The court found that when someone is shocked by a Taser device, their muscles release lactic acid. If someone is shocked repeatedly and for a prolonged period of time, the increasing amount of lactic acid can increase the risk of heart failure. 
 
Taser must pay $5 million in punitive damages and $1 million in compensatory damages to the parents of Robert Heston, who died in 2005 after being continuously shocked by stun guns for nearly 75 seconds.
 
In a press release, Taser stressed that the company's products were not found to be the sole cause of Heston's death. The release was titled: "Jury Finds Extended Taser Device Application 15 Percent Responsible for Arrest Related Death of Robert C. Heston."
