Lieutenant Peterson is a police officer in Los Angeles.

A Kiss of Shadows
When Meredith is taken to the police station covered in Branwyn's Tears, she is questioned  about the death of Alistair Norton, but the police are sceptical of her story. She, however, loses control after she proves to Detective Alvera that the Tears are real. The spell spreads among police officers.

Lieutenant Peterson grabs Meredith when she tries to go to young officer Riley, who had to be torn away from her. The contact causes Peterson be affected by the spell, but he manages to call for the help of female officers before he starts kissing Meredith.

Peterson has to be handcuffed before they manage to get him out of the interrogation room.

A Caress of Twilight
When Peterson finds out the Grey Detective Agency, especially Meredith and her guards, have been invited to murder scene by Lucy Tate, he becomes angry. He holds a grudge against Meredith for the Branwyn's Tears incident and Alistair Norton's death. Peterson bans them, and the whole Agency, from the case, and threatens that anybody talks to them about the case, saying they would be up on disciplinary charges.

When Teresa goes to the police station, and gives statement about what she saw at the murder scene, Peterson throws her statement into the trash in front of her.
