Former NFL quarterback Brian Hoyer announced the death of his sister-in-law, Carissa, in an emotional post on social media. "It is with a heavy heart that I write this. On February 13th, my little brother lost his wife Carissa suddenly and unexpectedly," Brian, 40, shared on Wednesday, February 18. "She leaves behind him and their four little girls, Josie, Lainey, Ellie, and Hattie. In an instant, he became a widowed father to four daughters under 12." Carissa was 36 years old, according to a GoFundMe page arranged in her memory, and married to Brian's brother Brett.
