The mother of Atatiana Jefferson died Thursday (Jan. 9) in the same that her daughter was shot and killed by police officer. Aaron Dean, last year.

According to CBS Dallas, paramedics were called to the family home where they found Yolanda Carr’s body. The cause of death is unknown, but Carr was reportedly battling a serious illness. Jefferson had moved into the family’s home to serve as a caregiver for her mother. After she was killed, Carr had little to no help.

The family’s attorney, Lee Merritt, released the following statement:

“It is with heavy hearts our office reports the passing of Yolanda Carr, the mother of Atatiana Jefferson. Atatiana was serving as a caregiver to her mother, Ms. Carr, at the time of her murder by Fort Worth police officer Aaron Dean. The family is devastated by Ms. Carr’s untimely death and is requesting for space to process and mourn. Police brutality impacts entire families, communities and generations. There is no doubt Ms. Carr’s recovery was complicated by the tragedy of her daughter’s death and the difficulty associated with the ongoing fight for justice. We will continue the fight in her honor. Please join us as we offer our prayers and condolences to this family during an incredibly difficult time.”

Carr’s passing comes less than two months after Jefferson’s father, Marquis Jefferson, suffered a fatal heart attack. He passed just weeks after his daughter was murdered.

Officer Dean was charged with murder after he shot and killed Jefferson through her bedroom window while she played video games with her 8-year-old nephew.

Dean’s body-cam footage showed that the officer shined his flashlight into Jefferson’s bedroom window and yelled “Put your hands up! Show me your hands!” Less than a second later, he fired a shot. Investigators say Dean did not identify himself as an officer at any point of the incident.
