Law & Order: Los Angeles Books Corey Stoll

Corey Stoll has snagged the role of Skeet Ulrich's on-screen detective partner in Law & Order: Los Angeles, a show rep says.

The Saltactor will play Detective Tomas "TJ" Jaruszalski, the partner of Rex Winters (Ulrich). TJ is described as a confident Los Angeles native with a disdain for the entertainment industry and an active social life, according to casting breakdowns. He sees the world as a complex place with lots of gray areas, which helps him both get into the heads of criminals and win them over.

Alfred Molina signs on to Law & Order: Los Angeles

Stoll, best known for a multi-episode arc on NCIS, also joins Alfred Molina on the spin-off series. The role of Assistant District Attorney Eva Price and police Lt. Park have both yet to be cast.

Stoll's casting was first reported by Deadline.

Production of Law & Order: Los Angeles is scheduled to begin Monday. The series premieres Wednesday, Sept. 22 at 10/9c on NBC.
