Murder suspect will hand over recordings from his Amazon Echo smart speaker

Amazon had previously fought Arkansas prosecutor's demand for data from device

CNN  — 

Amazon, go ahead and hand over the recordings in that murder case.

A high-profile attorney has taken over as lead counsel for an Arkansas man accused of killing his friend, a former police officer, after a night of drinking and football. A prosecutor had sought recordings from the defendant’s Amazon Echo smart speaker as evidence in the case, a request the online retailer had rebuffed.

According to a court document, lawyer Kathleen Zellner ended the legal tug of war Friday when she filed a motion saying her client, James Bates, would voluntarily hand over the recordings. Amazon provided the data to prosecutors later that day, the document says.

Zellner, who rose to fame as the attorney for Steve Avery in Netflix’s “Making a Murderer,” could not immediately be reached for comment at her Downers Grove, Illinois, office Tuesday.

She confirmed in a tweet, which was also posted to her law firm’s website, that the defense had agreed to hand over the recordings.

“My client James Bates is innocent,” the tweet said.

Request ‘overbroad’?

Amazon had pushed back against Benton County, Arkansas, Prosecuting Attorney Nathan Smith’s demand for information from the smart speaker, setting up a legal battle pitting investigators’ quest for technology-based evidence against American privacy rights.

“Given the important First Amendment and privacy implications at stake, the warrant should be quashed unless the Court finds that the State has met its heightened burden for compelled production of such materials,” Amazon’s lawyers wrote in a February memo seeking to quash Smith’s request for a search warrant.

In a statement sent to CNN last year, the company said, “Amazon objects to overbroad or otherwise inappropriate demands as a matter of course.”

Smith has said he hopes the voice-activated Echo – which answers users’ questions, plays music, reads news and connects to other smart devices – will provide information on how a man came to be found dead in 31-year-old Bates’ hot tub.

Kimberly Weber, who previously was lead defense counsel in Bates’ case, told CNN in December there was nothing useful on the device and applauded Amazon for protecting her client’s privacy.

Bates, who was arrested last year on suspicion of first-degree murder, is free on a $350,000 bond.

A discovery hearing in the case was scheduled for Wednesday, but it’s unclear if the hearing is still necessary now that Bates has acquiesced to the prosecutor’s request for the recordings.

This may be a first

As technology has become more integral to daily life, authorities have increasingly sought evidence from mobile phones, laptops, social media, even the “Warcraft” video game. Attempting to mine a smart speaker for information may be a first though.

Joel Reidenberg, the founding academic director for Fordham University’s Center on Law and Information Policy, told CNN it’s the first such case he’s seen, but he isn’t surprised that smart speakers are already the subject of a court battle.

While some might argue that voice technologies such as Echo, Siri or Google Home, which assist users with queries and tasks, come with a different expectation of privacy than, say, social media postings or Internet searches, Reidenberg said he feels such an attitude is naive.

According to Amazon, Echo works by constantly listening for the “wake word” – “Alexa” or “Amazon,” by default – and then records your voice and transfers it to a processor for analysis so that it can fulfill requests or answer questions. The recordings are streamed and stored remotely, and can be reviewed or deleted over time, Amazon says.

Tricks to try with your Echo

“How is that any different from you sitting at your keyboard typing?” Reidenberg asked.

The case

The Amazon Echo is always listening for its wake word.

The Amazon Echo became a subject of the November 2015 murder case because someone present on the night of the death recalled hearing music streaming through the device, prosecutors say.

Bates had invited two friends – one of them former Georgia police officer Victor Collins, 47 – over to his Bentonville home, where they watched college football, drank beer and shot vodka, according to the search warrant affidavit filed in Benton County Circuit Court. The men decided to get into Bates’ hot tub, and Bates said he went to bed around 1 a.m. When he awoke in the morning, Collins was floating face-down in the hot tub, the affidavit says.

Weber previously told CNN that Collins was Bates’ friend, and his death was a tragic accident, possibly stemming from his drinking. Collins’ blood-alcohol content at the time of death was .32, four times the legal limit to drive in Arkansas, she said.

“It’s not a murder at all. It’s an accident,” she said.

Investigators contend in the affidavit there were signs of a struggle, including injuries to Collins and Bates, a broken shot glass, dried blood inside the home and indications the patio and hot tub had been hosed down before police arrived.

Another smart device, Bates’ water heater, points to an exorbitant amount of water being used in the early-morning hours in what investigators believe was an attempt to cover up a crime, the affidavit says.

Weber said the amount of water was unremarkable and nearly equal to the amount of water used in the home 12 hours earlier.
