Tyler Barriss, 25, was arrested Friday on suspicion of making a hoax phone call to police in Wichita, Kansas.
Authorities in Wichita said someone made a prank call to 911 with a made-up story about a shooting and kidnapping. That call resulted in the death of an innocent man relatives identified as Andrew Finch, 28.
The hoax phone call was a case of swatting, authorities said, in which a person creates a false story to get a SWAT response to an address.
Authorities released the 911 recording in which a man said he'd shot his father in the head. The caller also said he was holding his mother and a sibling at gunpoint and threatened to light the house on fire.
When police headed to the home, they surrounded it and prepared to deal with a hostage situation. Finch answered the door and followed instructions to put up his hands and move slowly. But at some point, authorities said he moved toward his waistband and officers fired a single shot in fear Finch may have reached for a gun.
Authorities said Finch died at the hospital and that he was unarmed.
The police and FBI were investigating whether the hoax call stemmed from an argument over an online game.
In October 2015, Glendale police arrested a 22-year-old man with the same name for making bomb threats to KABC-TV. He was charged with two felony counts of a false report of a bomb to an agency of business and one felony count of criminal threats.
