Police arrested a handyman after finding a Jensen Beach woman’s body inside the septic tank of her home.

Martin County Sheriff’s Office said detectives discovered the woman’s body early Saturday inside the septic tank. The body is believed to be that of Cynthia Cole, 57.

Keoki Demich, 34, was soon after arrested on a charge of second-degree murder.

Cole had been reported missing last month after she had last been seen alive at the Jammin’ Jensen event in downtown Jensen Beach.

Although the body has yet to be positively identified, detectives said they have “every reason to believe it is that of Ms. Cole.”

No other details have been released.
