There's a new twist to the investigation on Sunday's episode of Whodunnit? While Cris and Melina are investigating Geno's body in the morgue, they come across something interesting: Giles' (Gildart Jackson) cell phone. In Geno's blood-splattered pocket. And no one — not even Giles — knows how it got there.
See if you can spot any clues in the exclusive clip below. How do you think Geno got his cold, dead hands on Giles' phone? Who do you think will be the next victim? And most importantly, who is The Killer?
Whodunnit? airs Sundays at 9/8c on ABC.
