Dr. Spencer Reid
Detective Matt Spicer
Matthew Gray Gubler
Born in Santa Monica, California, Matt had a regular childhood with his parents, Joe and Sylvia, and baby sister, Kristin, until August 28, 1984, when a serial killer who later became known as The Prince of Darkness (later to be identified as Billy Flynn) broke into their house. He woke Matt up, placed him and Kristin in the closet of their parents' bedroom, raped Sylvia in front of their eyes, killed Joe, and then her. Matt and Kristin were placed in the care of their grandparents and told that their parents had died in a car accident. Kristin was too young to remember the incident and Matt, who witnessed everything, chose to believe this, repressing the truth. He later became a police detective for the California PD. At one point, he was married, but they eventually divorced, presumably due to the strain of her being married to a cop. He had a daughter, Ellie, with her and gained custody of her because the mother frequently travelled in the line of work.
When Billy returns to California after travelling all around the U.S. for 26 years worth of killing, Matt investigated the crimes together with the BAU, mostly with Derek Morgan. When Garcia produced a complete list of Billy's crimes over the years, the truth about the Spicers' deaths was revealed to him. They then deduced that Billy was partially recreating his original California murders in order to taunt Matt and that he would go after Matt's family: Ellie and Kristin. Matt and Morgan drove to their home and found that Billy had already abducted them. Morgan figured that he would take them to Matt and Kristins' parents' old house. Upon arriving, Billy incapacitated and tied up Morgan and Kristin before forcing Matt to drop his gun by holding Ellie hostage. After Matt recognized the impact Billy had on his life, he made Morgan promise to keep Ellie and Kristin safe. Billy then shot Matt in the chest at point-blank range, execution style, and left, taking Ellie with him.
Matt did not survive the gunshot, and his death took a toll on Morgan's emotions. However, his death was not in vain: Ellie was released by Billy, who in turn was shot dead by Morgan when he took a couple hostage. Unfortunately, Kristin, badly wounded after being assaulted by Billy, died from her injuries.
