Natasha McKenna died in police custody.

From Wikipedia (because it would break my heart to try to re-write this story just to not gove credit here it's due):

McKenna was diagnosed with schizophrenia, bi-polar disorder and depression when she was 14 years old. She had a daughter who at the time of her death was 7 years old.

McKenna, a 37-year old woman was being held at the Fairfax County Adult Detention Center by the Fairfax County Police Department and Fairfax County Sheriff's Office in Fairfax County, Virginia, due to an outstanding warrant where she had attacked a police officer.[6]

After initially cooperating with officials, there was a week-long delay in transporting McKenna back to Alexandria, where better assistance could be provided -- the resources (i.e., legal representation to petition for a mental health hold) were required to be provided by the warrant-issuing city. Over this period, police became concerned because her mental health deteriorated. Because of the previous assault charge against her, she was restrained with handcuffs, arms behind her back, her legs shackled, and a spit mask placed over her head. During a struggle that lasted over 45 minutes, McKenna, a 130 lb (59 kg) woman who was 5 ft 4 in (1.63 m) tall, was tasered 17 minutes into a cell extraction. A sheriff's deputy used a stun gun to taser her four times because she wouldn't bend her knees to be put into a wheeled restraint chair.[8] The specialized team that was called in to address her condition was attempting to ready her for transport to Alexandria, Virginia.[9] The team was made up of six members of the Sheriff’s Emergency Response Team ("SERT") and were dressed in full-body biohazard suits and gas masks.

Shortly after being tasered, McKenna suffered cardiac arrest and lost consciousness, but was resuscitated on the way to Inova Fairfax Hospital by emergency responders, was placed on life support, but was determined to be brain dead and was removed from life support after five days. She was pronounced dead on February 8, 2015.

TASERS HIT THE NERVES AND MUSCLES, AND ATTACK THE HEART. Only the fittest suffer no consequences, and very few of us fit that category anymore. They should be a "last resort" weapon, in the same category as guns, but when one doesn't want to use deadly force, but here death may very well occur. It's NOT a weapon meant to control, stabilize, or calm a person.
