it's unclear how many times lambert was actually struck. >> it is a common practice for multiple officers to fire their taser because you need the darts to correctly seat into the person's body. every time you use that taser, every time you zap somebody with that taser, after you deploy it, you have to give a reason why. there has to be a reason why you continue to use that taser. >> reporter: while lambert's autopsy, quote, revealed three punctures suggestive of taser barb sites, the medical examiner ruled the cause of death an accident from, quote, acute cocaine intoxication following lambert's psychotic symptoms and violent behavior. none of the officers involved has been charged in the two and a half years since this happened. and the prosecutors told me today that she is still reviewing this case. today there was a court hearing about the word murder in this civil suit. the defendants are asking for that word to get struck or voluntary removed from the lawsuit. of course, jake, we will be keeping an eye on this case. >> pamela brown, thank you so
