Minor Characters

Jennifer (Peter Hale’s Nurse)
Jennifer was a nurse at Beacon Hills' Long Term Care Facility; a section of Melissa McCall's hospital. She helped Peter Hale with his crimes. Sometime later she was killed by him after "he got better." Her corpse is seen in the trunk of her car by Stiles Stilinski in Code Breaker.

In the season finale, it is revealed she stopped at Beacon Hills Animal Clinic to get a copy of a picture of a deer with a spiral symbol on it. This was to lure Laura Hale back to Beacon Hills, CA so Peter could kill her and become an Alpha.

Unger and Reddick
Unger and Reddick are minor characters in Teen Wolf played by Jonathan Kleitman and Hajji Golightly

In Lunatic Unger and Reddick come upon Scott and Stiles drinking in the woods and try to steal their liquor. Scott wolfs out and scares them in to leaving.

Reddick later disappears, presumably killed by The Alpha.

Unger is dragged through the woods by the Alpha, meeting his death by being thrown head first in to a trash fire.

Unger and Reddick are the arsonists involved in the Hale House Fire that killed most of the Hale Family.

Garrison Myers
Garrison Myers was one of the bus drivers at Beacon Hills High School. He was the focus of the episode Pack Mentality in which Scott saw Myers die in a dream and thought himself responsible for the attack.

In reality Myers was attacked by Peter Hale and died from his injuries later in the hospital.

According to Sheriff Stilinski, Myers was a former insurance investigator suspected of fraud in his investigation of the Hale House Fire.

Right before he died, he apologized to Derek Hale.
