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 issued over her suspected attack on a police officer in
Alexandria, Virginia. Fairfax County officials had notified Alexandria police, whom they expected to pick up the suspect. But, there was an unexplained week-long delay in their response, and Fairfax decided to transport the prisoner to Alexandria. They said her mental condition was deteriorating. In Alexandria, better assistance could be provided, namely, the resources (i.e., legal representation to petition for a mental health hold) that were required to be provided by the warrant-issuing city. Due to the previous assault charge against her, when McKenna was taken out of her cell, she was restrained with her arms behind her back and in
handcuffs, her
legs shackled, and a
spit mask placed over her head. 17 minutes into the 45-minute struggle to extract her from her cell, McKenna, who was and tall, was tasered. 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. Because she was classified as mentally ill, a specialized team was attempting to ready her for transport to Alexandria. The team was made up of six members of the Sheriff's Emergency Response Team ("SERT"); they were dressed in full-body biohazard suits and gas masks. Shortly after being tasered, McKenna suffered cardiac arrest and lost consciousness. She was resuscitated by emergency responders while being taken to
Inova Fairfax Hospital. There she was placed on life support. After five days, she was determined to be brain dead and was removed from life support. She was pronounced dead on February 8, 2015. == Response ==
