The remains of a woman nicknamed “Daisy Doe” for a daisy tattoo on her shoulder have been identified after 26 years, according to the Cherokee County sheriff’s office.

The Oklahoma medical examiner’s office Tuesday identified Doe as California native Jeanette Ellen Coleman, who was 31 at the time of her death. She was married to Charles Troy Coleman, a convicted killer who was executed by the state in 1990, two years after her death.

Coleman’s body was found floating in the Neosho River below the Fort Gibson Dam in Cherokee County on May 7, 1988, with a 28-pound cement block tied around her waist. The Oklahoma Lake Patrol reported at the time the body likely had been in the water for several days. Investigators believed Doe probably still was alive when she was dumped into the river.

Due to limited technology at the time, authorities were unable to identify the body.
