In a move that promises to raise new questions about electronic privacy, detectives investigating a murder in Arkansas are seeking access to audio that may have been recorded on an Amazon Echo electronic personal assistant.

So far, the online retail giant has resisted demands by the police and prosecutors in Bentonville, Ark., for the information. Without addressing the specifics of the case, Amazon said in a statement that, as a matter of course, it “objects to overbroad or otherwise inappropriate demands.”

The tug of war over access to the audio, which was reported by the website theinformation, began when the police started to investigate the death of Victor Collins, who was found on Nov. 22, 2015, in a hot tub at the home of James Bates, according to court records. Investigators discovered signs of a struggle, including spots of blood, broken bottles and pieces of the spa that were on the ground.

Detective Cpl. Josh Woodhams of the Bentonville Police Department wrote in an affidavit that he found an Amazon Echo on the home’s kitchen counter. The voice-activated device has seven microphones, and is equipped with sensors to hear users from any direction up to about 20 feet. Among other things, it can play music, make to-do lists, stream podcasts and provide real-time news and information.
