The Sullivans

Season 1



Coming from a prominent police family, Andrea is fiercely loyal to law enforcement. Having been the youngest child and only daughter of four children, she often felt overshadowed by her father & three brothers while growing up, and has often had to prove herself to be just as capable as men are in investigating & taking down suspects. This played a major part in her decision to put off joining the police and to work in the sheriff's office for a time instead. Being a black belt in Brazilian Jiu Jitsu, Andrea is known to be tough and can handle any situation. She is also emphatic towards victims of terrible crimes, especially children since she herself has two daughters. As a single mother, she is doing her best to raise Danielle and Piper to be independent women.
