Dennis (The Woman Who Fell to Earth)
From Tardis Wiki, the free Doctor Who reference
Dennis was a security guard at a Skylark construction site in Sheffield. He was talking to his granddaughter Daisy via his iPad when Tzim-Sha appeared outside.
Cutting the call, Dennis proceeded to confront the Stenza only for Tzim-Sha to kill him by freezing him to death and taking one of his teeth. His corpse was later found by the Thirteenth Doctor. (TV: The Woman Who Fell to Earth)
