RIZZOLI & ISLES Take on “Partners In Crime” in the Season Finale {PHOTOS}

In the summer season finale of Rizzoli & Isles, the squad rushes to solve a violent homicide case muddied by conflicting evidence. Maura is burdened with the major decision of whether to take in her recently paroled grandfather (guest star Richard Herd). Meanwhile, Jane and Casey (guest star Chris Vance) are forced to decide between their careers and their romantic relationship.

Rizzoli & Isles returns in early 2014 for the second half of its fourth season. TNT has ordered 15 episodes for the fifth season, which is slated to begin in summer 2014.

“Partners in Crime” airs tonight at 9/8c on TNT.
