'Hawaii Five-0' season 7 episode 10 spoilers, news: Team re-opens 10-year-old case of missing teenage girl; actor Keo Woolford dies at 49

Five-0 re-opens a decade-old cold case involving a missing teenager in the upcoming episode of the hit CBS procedural drama "Hawaii Five-0" season 7.

Titled "Ka Luhi (The Burden)," next week's episode centers on an investigation about a missing teen and a possible witness. According to the official synopsis for episode 10, Five-0 looks into a 10-year-old case of a missing teen when a boy suffering from PTSD undergoes hypnosis and discovers he might be a witness to the victim's murder. Also, Danny's (Scott Caan) sister, Bridget (guest star Missy Peregrym), comes to Hawaii for a business trip. However, he begins to suspect that she may be getting a bit too close to a co-worker.

On another note, Keo Woolford — an actor on the show — has died. As reported by Entertainment Weekly, Woolford's publicist Tracy Larrua confirmed that the actor/producer passed away Monday afternoon at a hospital in Oahu, Hawaii, just three days after suffering a severe stroke on Nov. 25.

A Honolulu native, Woolford had a recurring role in "Hawaii Five-0" as Det. James Chang. He also had small roles in notable feature films including "Godzilla (2014)," "Act of Valor (2012)," and "Happy Texas (1999)." Aside from acting, he also produced and directed an independent movie titled "The Haumana." Woolford was actually in the process of finalizing its sequel before his death. For the uninitiated, "The Haumana" follows a struggling luau show host who realizes the value of his culture after teaching a high school hula class for boys.

His co-star Daniel Dae Kim recently took to Twitter to share the sad news along with a heartfelt message. "As talented as you were, I will remember you most for your kindness. Thank you for sharing your light with us, @KeoWoolford. Rest In Peace," his post reads.

"Hawaii Five-0" season 7 airs every Friday night at 9 p.m. ET on CBS.
