Several former cast members of The Real World: New Orleans and The Challenge took to social media during Thanksgiving to mourn the death of Ryan Knight,  their co-star and friend.

He was found dead at a residence in Kenosha, Wisconsin on Thanksgiving Day. Knight was 28, police said.

Officers responded to a 911 call and discovered him unconscious and not breathing. Paramedics were unable to revive him. Knight's death is being investigated.

He had on Tuesday exchanged tweets with Sahar Dika, who starred with him on The Real World: New Orleans in 2010.

"Four years ago, we created a family in New Orleans that is unbreakable. Today, we lost you," she said on her Instagram page on Thursday, alongside a pic of the two.

"Knight, there were so many times we argued and screamed... But it always ended in a hug and a kiss and telling each other how much we loved each other," she said. "You are my family and I shared an experience with you and 7 others that will never be forgotten, not even parted with death."
