Robert Wagner will guest star on Tuesday’s episode of “NCIS” as a murder suspect, days after an investigation into the death of his wife, Natalie Wood, was reopened.

“After Anthony DiNozzo, Sr. [Wagner] is found in a car with a dead body in the trunk and no memory of the previous night, [Agent Jethro Gibbs] must figure out if he is capable of murder,” a synopsis of the episode reads. This is the “Hart to Hart” actor’s third appearance on the hit CBS show as the father of one of the agents.

Police said an investigation into Wood’s death was reopened after several people came forward with substantial and credible evidence.

Wood drowned in 1981 after spending the day with Wagner and actor Christopher Walken on Catalina Island and a yacht. While the “West Side Story” star’s death was ruled accidental, it has long been surrounded by speculation and mystery.

Dennis Davern, the captain of the “Splendour,” said in an interview with “Today” that he originally lied to police. Davern, who co-authored a book about Wood’s death, has said that he heard Wood and Wagner arguing before Wood’s death. Wagner released a statement, saying he hopes the new information in the case “comes from a credible source or sources other than those simply trying to profit from the 30 year anniversary of her tragic death.”

Police said Wagner is not a suspect. Even so, this “NCIS” storyline is clearly not the best thing for Wagner to be associated with at this time. But for CBS — which will, as The Wrap points out, air a “48 Hours” special about Wood’s death on Saturday — and its ratings? Well, that’s a different story.
