Rusty (Graham Patrick Martin) will finally find the break he has been looking for in the Alice Herrera case in the upcoming episode of TNT's police procedural series "Major Crimes."

In "Wish You Were Here," Cartermatt reports that Rusty will ask for Raydor's (Mary McDonnell) assistance as he locates Alice's brother, Gustavo. For a long time, the detective has searched for every possible lead that will point him to the secrets behind the girl's death. Will Gustavo finally be the missing link in the puzzle, or is he just another dead end?

Meanwhile, an interesting case will be delivered at the doorstep of Major Crimes Division. A YouTube video of a man goes viral. In the footage, he is all bloodied up while holding a gun and walking down the street. Raydor and her team must find out whether the man was targeted, or he committed suicide.

Last episode, the division was teamed up with a Federal Bureau of Investigation (FBI) agent in reopening a cold case of kidnapping. The only problem was that the operative had a shady past and the bureau had difficulty trusting him again. Upon investigation, they found out that the victim, Kevin, was involved in a drug deal before he disappeared. 

The ransom money they paid was traced in an account under the name of a 24-hour strip club. They also traced the drug dealer and it turned out he had been spending the money for Kevin's release. The teenager's body was buried underneath a hot tub in the dealer's backyard and that he had been shot in the head.

When they tried to locate the drug dealer again, he was already in the morgue with a head wound exactly the same as Kevin's. The team eventually found out that the kidnapping was Kevin's idea to get back at his parents and that his passing was an accident. His friends were the ones who killed the dealer after they found out that he had been spending the money on the strip club.

Meanwhile, Raydor and Flynn (Anthony Denison) decided that it was time to tell Assistant Chief Taylor (Robert Gossett) that they were dating.

"Major Crimes" airs Monday at 9 p.m. EST on TNT.
