Emily Wilson was a friend of Aaron Kasden.
In 2043 Emily was expelled from school for assaulting a classmate. She was 12 or 13 at the time. She was homeschooled by a holographic teacher since then. Her aptitude test scores were 'off the charts'.
Emily met Aaron online and they became friends.
After Aaron was killed in 2047, her family moved to Arizona. Aaron had been coming to visit Emily that night and had mistaken the yard he entered as belonging to the Wilson's. Eleven months later she disappeared from home and was listed as a missing person by her parents.
Emily had traveled back to the City to seek revenge on those she held responsible for Aaron's death. Emily was a highly skilled hacker and she used those skills to enact her revenge. She hacked into the Synturion Smarthome security system of Linda and Michael Bennett and arranged their deaths to coincide with the one year anniversary of Aaron's death. Next, she targeted the Synturion in-house council, Peter Newsom and tricked his Smarthome security system into triggering a fire alarm and had it believing that there were no living creatures inside the house. The house sealed off all exits and sucked out all oxygen from the house, killing Newsom in the process.
Her final revenge was to kill Kay Stenson. In order to do so, she gained control of the Synturion company building, including the new S.A.M. android models. The Police had identified her as the main suspect in the killings of the Bennett's and Newsom at this point, due to all of the victims receiving an email which included a picture of Aaron that came from an image of Emily with Aaron. With the assistance of Nico Galasso, Detective John Kennex and Dorian entered the Synturion building to protect Mrs. Stenson. Dorian tracked Emily down to the Server room while Detective Kennex destroyed the S.A.M. android.
Emily was arrested and charged with the murders of the Bennett's and Newsom.
