Patricia Roker, Al Roker’s sister, died due to a stroke. The Today program presenter announced the news on Instagram, alongside a photo of his late mother and sister, Isabel.

According to Roker’s caption, Patricia’s nickname was Boo, and she leaves behind a devoted husband, Nigel, and her children, Langston and Adam.

Roker’s coworkers, including Sheinelle Jones, responded to the post with loving emoticons. Roker was hospitalized earlier this month for blood clots in his legs and lungs and was released a few days ago.

He also recently disclosed the death of a close friend, Mark Traub, who died of leukemia after a protracted struggle.

Roker has been struggling with his health challenges and the loss of his sister and friend. He was admitted to the hospital in early November with blood clots in his legs and lungs and was released on Thanksgiving. He was brought back to the hospital the next day, though.

According to an eyewitness, Roker’s health was concerning, but once he was admitted to the hospital, he improved. Deborah Roberts, Roker’s wife, was naturally outraged, according to the eyewitness. Roker was just released from the hospital and is now back at home with his family.
