Can Alexa help solve a murder case? Police think so, but Amazon won't give up the data

When police responded to a home in Bentonville, Ark., one Sunday morning in November 2015, they discovered Victor Collins' dead body in the backyard. Police records describe a grim scene: Collins' body was floating face up in a hot tub, his left eye and lips dark and swollen. The resident who had called 911, James A. Bates, told police that he and a few work buddies, including Collins, had stayed up the night before watching football and drinking. Bates agreed to let two of them crash at his house, then went to bed, he told police. Shortly after he awoke, he said, he spotted Collins' lifeless body in the spa.
