Quick Summary

The article reports on a four-minute standoff in Times Square where a woman was stabbed and killed by Pamela Cisneros, who allegedly attacked two people with knives despite multiple officers discharging Tasers that failed to subdue her. According to a retired police sergeant, Steve Keller, obesity can affect the Taser's effectiveness because a large layer of body fat can interfere with the connectivity between probes. The standard Taser is designed to fire two probes connected by wires, which travel through the body and trigger involuntary muscle contractions. Keller notes that mental health may also play a significant role in how a person responds to a Taser, citing Cisneros' documented history of mental health incidents with the NYPD.

Story summary

Pamela Cisneros, a 49-year-old woman, allegedly stabbed two people in Times Square last Monday, killing one and injuring another. A four-minute standoff ensued as police tried to subdue her with Tasers, but the devices were ineffective. Despite multiple Taser deployments, Cisneros continued to advance on officers with knives, prompting two officers to open fire and strike her. She was taken to Bellevue Hospital, where she was pronounced dead. The incident has raised questions about why Tasers sometimes fail to subdue suspects, particularly whether obesity or body composition can impede their effectiveness. A standard Taser is designed to fire two probes that deliver electrical pulses into the body, but it's unclear why Cisneros' body responded differently. The manufacturer, Axon, notes that for the device to be effective, two probes must make contact with the body within a certain distance of each other, which may not always occur due to factors such as weight or body composition.

"As multiple officers discharged Tasers, which proved to be ineffective, the subject continued to advance toward our officers with the knives," Jessica Tisch, New York City police commissioner, said in a news conference that evening. asserted
Tisch → discharge → conference
When the Tasers failed to subdue Cisneros — who stated, "I’m not dropping anything. asserted
I → fail → anything
I would rather kill both of you" — two officers opened fire, striking her. asserted
officers → kill → her
Cisneros was taken to Bellevue Hospital, where she was pronounced dead. asserted
she → take → Hospital
The incident sparked broader questions about why Tasers sometimes fail and whether obesity or body composition can impede their effectiveness. asserted
obesity → spark → effectiveness
A standard Taser is designed to fire two small, barbed probes connected to the device by insulated, conductive wires, according to Axon, the manufacturer. uncertain
Taser → design → Axon
"Electrical pulses travel along those wires and into the body, triggering involuntary muscle contractions," Axon’s website states. asserted
website → travel → contractions
"For NMI to occur, it is best that two probes make contact 12 inches (30 cm) or more apart." asserted
probes → occur → contact
Officers are trained to aim for those areas." asserted
Officers → train → areas
Steve Keller, a retired police sergeant in Blue Ash, Ohio, said the most common causes of Taser failure include clothing, probe placement, substance abuse by the perpetrator and connectivity between probes. asserted
causes → say → probes
However, obesity can affect the Taser, he said, as a large layer of body fat could interfere with the connectivity. " uncertain
layer → affect → connectivity
The purpose of the Taser is neuromuscular in capacity," Keller told Fox News Digital. asserted
Keller → tell → Digital
Officers are trained to aim for those areas," he said, just as they are also trained to adjust their aiming for clothing and the distance between them and the subject. asserted
they → train → them
If one of the probes hits the abdomen and the person is obese, it can affect the connectivity of the two probes, according to Keller. uncertain
it → hit → Keller
"If one probe hits the person and the other probe misses, the Taser will not work," he said. asserted
he → hit → person
For example, if one probe hits a subject in the thigh and the other probe hits a thick bubble jacket, there’s a good chance the officer won’t have good connectivity, Keller said. asserted
Keller → hit → connectivity
"The same could be considered if there is a large layer of body fat — they could still feel it, but it might not be as effective." Referring to Cisneros’ case, Keller emphasized that mental health may also play a significant role in how a person responds to a Taser. uncertain
person → consider → Taser
Tisch confirmed at the press conference that the suspect had a documented mental health history with the NYPD, with one incident in 2018 and another in 2019. asserted
suspect → confirm → 2019
Dr. Marc Siegel, Fox News senior medical analyst, agreed that body composition can affect the Taser’s effectiveness. asserted
composition → agree → effectiveness
"Tasers are much more effective for muscle than fat because muscle conducts electricity much better, and the Taser delivers a high voltage," he said. asserted
he → conduct → voltage
"In an obese person, it is more difficult to find an area that conducts electricity." asserted
that → find → electricity
Fox News Digital reached out to Axon, the NYPD and obesity organizations requesting comment. asserted
