Fellow actors have paid respects to Kim Joo Hyuk, who passed away on October 30 after a car accident. "Running Man" cast members like Yoo Jae Suk, Song Ji Hyo, Lee Kwang Soo, Haha, Kim Jong Kook and Ji Suk Jin were spotted arriving at the mortuary at Asan Medical Center in Seoul on Tuesday, October 31.

Joo Hyuk's girlfriend, actress Lee Yoo Young, was filming the SBS variety show when she learned of his sudden passing. She reportedly was unable to continue filming due to shock. Following the devastating news, filming of the show in Busan was halted and all the members and guests immediately returned from Busan.

"2 Days & 1 Night" stars Cha Tae Hyun, Kim Jong Min, Kim Joon Ho and Defconn were also mourning the death of their former castmate. The foursome, along with newest cast member Yoon Shi Yoon, all came to the mortuary on Tuesday. Jong Min and Joon Ho's eyes looked swollen, while Defconn couldn't hold back tears and sobbed hard as he made his entrance. Another cast member, Jung Joon Young, couldn't come because he's filming "Law of the Jungle".

Also having paid respects to the late actor were Choi Min Sik, Kwon Sang Woo, Son Ye Jin, Han Ji Min, Yoo Jun Sang, Ryul Joon Yeol, Kim Ji Soo, Park Seo Joon, Son Hyun Joo, Kim Ji Soo, Kim Hye Sung, Jang Geun Suk and many others.

Joo Hyuk's girlfriend Yoo Young is reportedly mourning at the mortuary alongside his family. His brother oversaw the wake and his agency Namoo Actors' CEO Kim Jong Do was also there to mourn. His funeral is scheduled to take place on November 2.

Meanwhile, police have revealed the cause of the death. Based on the result of autopsy, police said that a traumatic head injury was the true cause leading to the actor's death, not a heart attack as reported before.

Police are still awaiting results of tissue examination to find out if there was an issue in the heart and/or possible drug consumption which could play a role in his death. The results will be released next week.
