A prized show dog will be the primary suspect in the death of its trainer in the upcoming episode of "Rizzoli & Isles."

In Jane "Sister Sister," Cartermatt reports that (Angie Harmon) and Dr. Maura's (Sasha Alexander) will be baffled to find out that the death of a dog trainer is being connected to a Rottweiler. Apparently, the woman is found in her home, with only the dog accompanying her. The dynamic duo has some serious investigating to do to find out if the killer in the case is indeed an angry animal or a human being.

Meanwhile, Maura will again be placed front and center in the new episode. While deep in the said investigation, she will be having some "peculiar interaction" with Kent (Adam Sinclair). What could the forensic expert and her sexy assistant be doing? Will viewers finally see Maura in a sexy encounter with the boy from the military?

Last episode, another case mystified Jane and her partner after they found a college student murdered while hiking. Stuart apparently fell off the cliff, but upon investigation, they found out that his fingers were broken. This meant that someone stamped on them to force the victim to fall to his death.

While checking his phone, the two were surprised to learn that he had 32 virtual girlfriends. Stuart was apparently affiliated with a dating app called "Your Perfect Mate." The company had been paying him to keep "lonely women" happy by pretending to be their beau on line.

One particular woman named Heather caught their attention. She had been sending suspicious text messages to the dead guy. At first, they believed that it was her frustrated husband who was the killer. But then they found Heather attempting to burn him alive. It appeared that she was slowly losing her mind and she killed Stuart because he did not really love her.

"Rizzoli & Isles" airs on Tuesdays at 9 p.m. EST on TNT.
