Yvonne Burns

Yvonne Burns is the aunt of Derek Morgan, who appears in the Season Six episode Big Sea. She is the sister of Morgan's late father

Background
Yvonne's daughter, Cindy, became endangered when a stalker set his eyes on her. At the time the BAU had been called in to create a profile for the case, but things took a turn for the worse for Morgan when Cindy disappeared, the stalker killed himself two weeks after their arrival and there was not any trace of her found.

Since then, whenever Yvonne hears of a case the BAU is investigating that raises the chance of Cindy being one of the victims, she would call Morgan for verification. She has a good relationship with her nephew and Morgan cares for her aunt very much.

Big Sea
When the BAU is called in to investigate due to series of skeletons having been pumped out of the ocean while a Jacksonville beach undergoes cleaning, this prompts another call from Yvonne after she watches in the news Hotch giving up details of where this unsub would find and abduct his victims and asking for cooperation from families and friends of missing people in those areas. The call arrives at the same moment that Morgan learns that one of the skeletons found has been determined to belong to a woman who matches Cindy's overall physical description. Morgan tells her that they don't have much information about the victims yet.

Yvonne is not convinced and travels to Jacksonville and visits Morgan just as the BAU is giving a profile on the unsub and offers him her daughter's hairbrush for DNA comparison, in answer to the plea made during the press conference.

When the unsub is captured, Morgan shows him pictures of missing persons, including a picture of Cindy. The unsub correctly guesses that Morgan has a personal connection with her and taunts him, saying that when he killed her she was shouting for her cousin to help her. Morgan instantly realizes he is lying and leaves. He returns to Yvonne and tells her the unsub has recognized Cindy as one of his victims but chooses not to tell her that he knows he's lying. Yvonne understands that it means her daughter is dead and hugs Morgan while crying in grief and relief for finding the closure she had been seeking all along.
