Pierson, FL – A great-grandmother has been arrested for attempting to kill her disabled great-granddaughter during an alleged murder-suicide incident. Deborah Collier, 69, faces one count of attempted murder in the first degree.
The events transpired on Monday afternoon in and around DeLand and Pierson, a region situated about 30 miles from Daytona Beach. A letter discovered at Collier’s residence raised alarm, leading law enforcement to consider her suicidal and search for her in a silver Chrysler Pacifica.
Upon locating the vehicle, deputies found Collier’s great-granddaughter, 13-year-old Sophia Abbott, asleep in the passenger seat. The deputy observed that Sophia was breathing normally and showing no immediate signs of distress.
Collier informed officers that Sophia, who is non-verbal, autistic, and incapable of independent movement, could potentially become aggressive if awakened. Backup was requested to ensure both Collier and Sophia received appropriate assistance.
As the situation unfolded, a second deputy arrived and discovered signs of distress surrounding Sophia, including white pill residue and signs of urination. Paramedics were called in to assist, and Sophia was taken to a local hospital for evaluation.
A search of the vehicle revealed prescription medications and a letter that expressed Collier’s despair related to her family situation. The letter contained a plea and described Collier’s desire for peace from the stress imposed by caregiving for Sophia.
During discussions with law enforcement, Collier explained the challenges of caring for Sophia, stating that both she and her husband had been the girl’s sole guardians. Collier outlined Sophia’s severe disabilities, which require constant care and have posed significant physical challenges for her and her spouse.
Collier mentioned that her husband was often critical of her and that tensions had escalated within the family due to caregiving issues. She expressed her concerns about Sophia’s future and her own inability to cope.
Law enforcement documented Collier’s comments, including her acknowledgment of the letters found in the vehicle. Collier indicated that the letters were part of her planning process, and she reflected on her intentions concerning Sophia.
Ultimately, Collier admitted to having thoughts of ending their lives. She expressed the belief that if she could not care for Sophia, she could not leave her behind.
Collier remains in custody at the Volusia County Jail with no bond. She is scheduled to face arraignment on January 22, 2026.
