Emily

Emily was the sister of Carla Matheson, seen during Day 2.

Day 2
CHP Officer Raymond Brown transferred Megan Matheson into the custody of Emily, Megan's aunt. This occurred because Megan's au pair, Kim Bauer, and her boyfriend Miguel were suspects in the murder of Megan's mother, Carla.

Because Aunt Emily lived out in Santa Barbara, Kim was relieved that Megan would be safe, since Emily's home was far from Los Angeles and the nuclear threat during that day.
