She lived in Pennsylvania where she was the next-door neighbor to Bill Weller and his family. She was a single mother and when she had night shifts at work, she asked the Wellers to look after her daughter, Taylor, who befriended Kurt Weller.
When Taylor went missing and Bill Weller became the prime suspect of the girl's disappearance, she never spoke to the man again, she was even displeased to see him on Taylor's memorials.
After leaving a café where she met with Kurt Weller, her car was crashed by Roman; she survived the crash but Roman suffocated her to death. This was to ensure Remi's cover as Taylor when she would infiltrate the FBI, as Emma's DNA would've disproved her cover story.
