Saturday Night Live writer Jimmy Fowlie is offering more details about the last time he heard from missing sister Christina Lynn Downer. "Christina is very attached to her dog Rex. He's a min pin and if you see her chances are he'd be with her," Fowlie captioned an Instagram post on Tuesday, December 23. "Last seen in Koreatown. I heard from her on Nov 26th. She was active on social media up to Dec 15th." He added, "At this time the detectives have advised us not to share certain details so we don't compromise the case. Thank you to everyone who has gotten the word out.
