Did an Amazon Echo personal assistant witness a murder? US prosecutors want to know

Amazon’s connected personal assistant Alexa may have witnessed a murder. But will she talk?
Investigators in Arkansas recovered the Amazon Echo speaker infused with artificial intelligence from a murder scene, and want to know what Alexa heard, according to lawyers on both sides.
The case centres around Victor Collins, 47, who was found strangled in November 2015 in a bathtub of the Bentonville home of James Bates, who is accused of the crime.
In the investigation, an officer found an Amazon Echo device at Bates’s house - the small cylinder-shaped speaker which responds to voice commands under the name “Alexa.”
Prosecutors have obtained a search warrant which would require Amazon to release any relevant data from the device, according to a statement from Benton County prosecutor Nathan Smith.
“It is incumbent on law enforcement officers to examine this data to determine if it has any relevance to the crime,” Smith’s office said in a statement.
The case raises questions about privacy and technology at a time when more devices are recording data about users’ movements and actions.
