“Person of Interest” fans could be bidding adieu to the CBS series this year. Although the crime drama has yet to get a premiere date for its fifth season, executive producer J.J. Abrams revealed that the coming episodes may be the last for the show.

CBS is presenting at the Television Critics Association press tour in Pasadena, California, Tuesday, but Abrams spoke about “Person of Interest” while participating in a panel discussion of his new Hulu miniseries, “11.22.63.” He was unable to confirm a premiere date for the highly anticipated fifth season of “Person of Interest,” but did hint the series didn’t have a bright future at CBS.

“My guess is it is the final season,” Abrams told TVLine at the event. “The only heartbreak there is how much good story there was to come if it were to have continued.”

“Person of Interest” recently made headlines again when it was left off the network’s new schedule for March. CBS announced the premiere of “Rush Hour” and a time slot change for “Elementary,” but didn’t list “Person of Interest” Season 5.

The fourth season concluded in May with Finch (Michael Emerson) and Root (Amy Acker) working to save The Machine before coming face-to-face with Samaritan operatives. Fans have no idea what will happen next, but it has been confirmed that fan-favorite actress Sarah Shahi will return as Shameen Shaw after going on maternity leave during Season 4. It’s unclear how Shaw will be worked back into the storyline.
