Dennis McGrath

Sergeant Dennis McGrath was an officer with the Los Angeles County Sheriff's Department. He was one of the officers that responded to Jack Bauer's staged convenience store robbery in Somis.

Day 4

When Sgt. McGrath arrived on the scene, he called Jack. Jack threatened to kill the hostages if the police try to take the store. Sgt. McGrath told Jack to let the hostages go but keep Officer Bill Dotson. Jack said he would think about it and hung up.

Later, Jack exited with Kalil Hasan as a hostage. McGrath ordered his officers to lower their weapons. Jack left in Hasan's car, but McGrath called in a roadblock (set up by Sgt. Paulson) to catch them.
