VOLUSIA COUNTY, Fla. — A DNA match confirms that human remains found in Flagler County belong to Mandy Ciehanoski, a woman murdered in 2011, the Volusia County Sheriff's Office says.

Ciehanoski was reported missing February 14, 2011, a week after she was last seen by her family.

Her convicted killer, Michael Annicchiarico, is serving a life in prison for second-degree murder.

Detectives determined Annicchiarico, who had an on-again, off-again relationship with Ciehanoski, was with her on the day she disappeared, despite his statements that he had not seen her in two years.

However, investigators found evidence showing that the two were together a week before she was reported missing.

Detectives said they found blood-stained bed sheets stuffed in a trash bag in Annicchiarico's closet. In the trash outside of his home, they found discarded latex gloves, with one that had blood inside of it, they said.

"The blood in the glove matched Annicchiarico’s, while a DNA analysis of the blood in the car and on the linens showed that there was an almost mathematical certainty that it came from someone related to Ciehanoski's parents. Sheriff’s investigators tried to question Annicchiarico about the blood, but he got nervous and said he thought he needed a lawyer," a 2011 Volusia County Sheriff's Office news release said.

In 2014, he pleaded no contest to second-degree murder and was sentenced to life in prison.

Ciehanoski's body was found just north of Ormond Beach in November 2016. From there, the remains were sent to the University of Florida C.A. Pound Human Identification Laboratory by the St. John’s Medical Examiner for analysis, but it was not until newly-released DNA test results that determined it was her remains.

It's taken eight years Debra Ciehanoski to get closure on where her daughter’s body has been. Now, she says she can finally have some peace of mind.

“I’m not sure how many remains were found because of how he killed her," Debra said. "I pray that they found all of her ... "

Debra plans on having a proper funeral and  burial for her daughter when the remains are released to her.
