Jimmy Fowlie has a devastating update about his family.

Four months after the Saturday Night Live writer asked for the public’s help in locating his sister Christina Fowlie, he shared that the Los Angeles Police Department informed them that the case has “officially transitioned from a missing person to a homicide investigation.”

“The LAPD has informed our family that Christina is no longer alive,” Jimmy wrote in an April 29 Instagram post. “Our prayers for her to be found safely have transformed into prayers for the truth to be revealed and for those responsible to be held accountable.”

The 40-year-old noted that he and his family believe her phone and social media had been compromised in the weeks before she was reported missing in December, adding that those in possession of her phone “used it to hide the fact she was gone, to ask for money, and to create a false narrative that she was going ‘off the grid.’”
