Sharon Mayford

Sharon Mayford, a.k.a. "The Bomber", was a serial bomber and hitwoman who appeared in Season Eleven of Criminal Minds.

Background
At some point in Mayford's life, her father Earl died from unspecified causes, her mother Tiffany committed suicide for unknown reasons, and her brother Doug died in a motorcycle accident in 2002. Brian Cochran revealed that, as an adult, she received her training (and likely her bomb-making skills) from Mossad. She eventually became a hitwoman and member of a network of hitmen that cropped up after the dismantlement of the Silk Road by the FBI in 2013. She was hired by Cochran to kill a bureaucrat who had forgotten to pay him a bribe on time. As a result, on August 13, 2015, Mayford killed a total of at least 173 people, including the bureaucrat, in several explosions at a container storage station in Tianjin, China.

Entropy
In 2015, the BAU began investigating the network after it set its sights on Garcia. When they began to close in on them and two of their own are killed, Mayford hatched a plan with Cat Adams to attack the BAU. She came to Harry & Glenn's Grill and Bar with Cat before Reid and the others arrive. As Cat takes Reid hostage, Mayford operates secretly, setting up explosives powerful enough to destroy an entire city block and kill thousands. After a while, Mayford prepares to detonate the bombs. However, she is found by Morgan and Lewis, who deduced her gender earlier. The two agents subdue her and grab away from her the phone she planned to use to set off the bombs.

Modus Operandi
Mayford would kill the victims in her contract kills by using bombs, hence her nickname. It is likely that she would be contacted and paid by her clients with each contract kill. Exactly how she committed the container storage station chemical explosions is unknown. During the attempted Harry & Glenn's Grill and Bar bombing, she used several C4 bombs attached to the restaurant's gas pipelines, which would cause an explosion powerful enough to take down an entire city block.

Profile
No official profile of Mayford was made by the BAU, since they focused on the network as a whole. Although it was initially believed that Mayford was male, the BAU switched their focus on women from the implication of Cat's comments about gender bias. They also briefly described her as being extremely paranoid due to her usage of explosives in her contract kills.
