In 2014, Abtahi starred in the A&E series Those Who Kill, the American version of the Danish crime TV series of the same name (Den som dræber in Danish). The show aired following new season 2 episodes of the network's hit series Bates Motel.
The American version of the show revolves around Catherine Jensen (Chloë Sevigny), a homicide detective who works with forensic psychologist Dr. Thomas Schaeffer (James D'Arcy) to track down serial killers. All the while, Jensen works to discover the story behind her brother's disappearance. Abtahi plays Jensen's co-worker Detective Jerry Molbeck, who investigates the strange murder cases alongside her. He is loyal and hardworking, allowing Jensen to take the reins of the investigation as he does research.
As Jensen's obsession with her missing brother and her theory that her stepfather is involved takes all of her focus, she leaves Molbeck in harm's way and he ends up face to face with the killer. Despite the interesting characters and capable actors, the series didn't do very well, and the network pulled the show from their channel after two episodes, relaunching it on their sister network, the Lifetime Movie Network. It was not renewed for a second season.
