POLK COUNTY, Fla. (WFLA) — The Polk County Sheriff’s Office is investigating a “double murder” after they believe a mother killed her two children before herself Sunday afternoon.

According to the sheriff’s office, the mother killed her 19-year-old daughter and 10-year-old son following a custody dispute with the boy’s father, who lives in Maine.

Polk County Sheriff Grady Judd said a judge issued an order directing the mother, 43-year-old Brandy Hutchins, to turn over her 10-year-old son to a PCSO district station by 6 p.m. Friday, but she never did.

Judd said deputies worked through the weekend trying to locate the 10-year-old boy, but officials were met with a horrific discover Sunday afternoon.

Around 12:30 p.m., deputies were called to a mobile home in the Waverly area of Lake Wales, where they found Hutchins and her two children dead from an apparent murder-suicide.

“I can’t imagine a more horrific set of circumstances,” Sheriff Judd said. “My heart breaks for all of the family. We are devastated for this 10-year-old child all because mom did not want to turn the child over to the rightful father pursuant to a court order.”

Judd said Hutchins had no criminal history and there were no indications of threats of violence in the court records.

The Polk County Sheriff’s Office will continue to investigate this double murder-suicide.
