In the upcoming season of NBC's supernatural drama "Grimm," the story will emphasise on the events occurring in Portland Police Department. After Captain Renard quit the force to become the mayor, recent reports state that Chris McKenna of "One Life to Live" fame will join the cast as a "formidable" lieutenant.

According to TV Line, McKenna will portray the role of Lt. Grossante, a "formidable and driven" and "military-type" police officer, as stated in the official description.

McKenna announced his casting through his Twitter handle that reads, "Very excited to be joining the cast of @NBCGrimm More details as I get em!" For now, McKenna has signed for one episode. However, he might return in the further episodes.

Though there have no official confirmation, there is a significant possibility that McKenna's character of Grossante will be revealed as a Wesen. It has happened previously with several characters of the show and fans are looking forward to find the real truth behind his identity.

McKenna has worked in several TV shows and movies prior to his debut in "Grimm." Some of his most notable works were in prominent shows like "90210," "Castle," "NCIS: Los Angeles," "Private Practice," and "The Young and the Restless." Recently, he also appeared as Dr. Hayden in "The Bold and the Beautiful."

The premiere date of "Grimm" Season 6 is not yet revealed by NBC. Talking with TV Line about whether the sixth season will be the final one or not, David Greenwalt, executive producer of the series, said: "There may or may not be more episodes. It may or may not be the last season. These are things we don't yet know. We're certainly thinking of arcs for next year, and then [the episode order] will determine how long it takes to do that."

Season 6 of "Grimm" has been trimmed down to 13 episodes instead of the usual 22 episodes in every season.
