US police investigating a murder have tussled with Amazon over access to data gathered by one of its Echo speakers. The voice-controlled device was found near to a hot tub where the victim was found dead amid signs of a struggle. According to court filings, Amazon was issued with two search warrants but refused to share information sent by the smart device to its servers. However, the police said a detective found a way to extract data from the device itself. The accused killer has yet to be put on trial and it is not clear whether the information ultimately proved useful to the investigation.
