Portrayed by Jake Abel
Episode Saving Sammy
Status Arrested

Doug Sommer was Ruby Harris' boyfriend who killed her parents, Lisa Harris and Steve Harris, when he found out they were moving to Vermont.

Doug came from a troubled home and regarded the Harris family as the one he'd never have, feeling a great affinity towards them. When Ruby's brother Brent Harris got into a special school in Vermont, Doug was upset, as he adored Ruby and would've had everything he loved taken away from him since her entire family was planning to move there. He held up Steve and Lisa at gunpoint in their car, admitting he was sorry but he couldn't let them take Ruby away from him. Despite Steve saying they wouldn't go to Vermont, Doug didn't believe them, and proceeded to shoot them both to death in front of Brent. He made sure sure Brent's pet fish Sammy was safe before running away.
