THE TEAM INVESTIGATES THE DEATH OF AN ACAPELLA SINGER ON "BONES" SATURDAY, DECEMBER 31, ON FOX

Kirstin Maldonado ("Pentatonix"), Mitch Grassi ("Pentatonix"), Scott Hoying ("Pentatonix"), Jordan Fisher (GREASE: LIVE, "Teen Beach Movie") and B.K. Cannon ("Switched at Birth") Guest-Star

The team investigates the death of the leader of the Lynwood University male acapella singing group, "The Whippersnaps," whose body was found in the school rat lab. The victim recently kicked out Ian Jansen, one of the group's best singers (guest star Jordan Fisher), sending Booth and Aubrey to question Ian and other current members of the male group (including guest stars Mitch Grassi and Scott Hoying) and some stars of the competing female acapella group (including guest star Kirstin Maldonado) to get a handle on the group dynamics and what could have led to the murder of one of their own. Meanwhile, surprising information about Aubrey's own college experience is brought to light, Hodgins applies for an experimental nerve regeneration study, Booth tries to plan a summer trip with Parker (guest star Gavin MacIntosh) and a new intern joins the Jeffersonian lab (guest star B.K. Cannon) in the "The Strike in the Chord" episode of BONES airing Saturday, Dec. 31 (8:00-9:00 PM ET/PT) on FOX. (BON-1116) (TV-14 D, L, V)
