VOLUSIA COUNTY, Fla. – A woman from DeLand, aged 69, has been taken into custody following an alleged attempt at a murder-suicide involving her 13-year-old great-granddaughter, who has disabilities, as reported by the Volusia Sheriff’s Office.

The incident came to light on Monday night when a suicide note was discovered at Deborah A. Collier’s residence in the Daytona Park Estates area. Authorities tracked her vehicle near Seville and during a traffic stop, they found the teenager in an unconscious state in the passenger seat.

Collier claimed the young girl was merely asleep, yet officers observed white pill residue on her body and reported her as “totally unresponsive,” according to the sheriff’s office. The girl was rushed to a hospital for medical care.

Further investigation revealed prescription medication bottles and an additional typed note in Collier’s purse. The note suggested she planned to end both her and her great-granddaughter’s lives due to family-related stress, according to officials.

The teen girl required comprehensive, 24-hour care due to her disabilities, and Collier and her husband have been the sole caregivers since the girl’s birth, according to sheriff’s officials.

“The constant demands of caretaking have contributed to significant stress in the family. Collier was opposed to the idea of the victim receiving care in an assisted-living facility and said she believed that no one would care for her like family‚” the sheriff’s office said. “In her desperation due to these hardships, Collier made a plan to end her great-granddaughter’s life followed by her own.”

Collier faces an attempted first-degree murder charge and was booked into the Volusia County jail.
