POLK COUNTY, Fla. — Prosecutors continue to build their case against Cheyanne Jessie.

The Lakeland woman is accused of killing her father and six-year-old daughter.

She is facing the death penalty.

On Friday, jurors heard from one of the detectives who interviewed Jessie after she reported her father, Mark Weekly, and daughter, Meredith, missing nearly two weeks after they died.

Detective Matthew Newbold told jurors Jessie changed her story numerous times and eventually told them where the bodies were.

During the interview, Jessie said her boyfriend Matthew Monroe had threatened to leave her if she didn't get her daughter help for her behavorial issues, and her father had called her a poor mother.

She allegedly told Newbold she was pregnant with Monroe's child.

"What did she tell you about that?" asked prosecutor Kristie Ducharme. "She said she had a miscarriage because her daughter punched her," said Detective Matthew Newbold.

Newbold testified that Jessie changed her story about her father and daughter missing when he came back to the interview room with a text she'd allegedly sent her father's girlfriend, letting her know that her father was in Georgia.

"Did her story begin to change?" asked Ducharme. "Yes," Newbold replied.

Newbold said Jessie then confessed, saying her dad attacked her.

"They were basically struggling over the gun, at which time she said the gun went up by his head and went off," Newbold explained, recalling what was said during the four and half hour interview.

She allegedly told Newbold her daughter was stabbed in the neck by accident during the scuffle.

Newbold said Jessie told him she didn't call 911, and after she had moved the bodies, she explained how she tried to hide blood stains on the floor and furniture.

Newbold said she then gave him the keys so authorities could retrieve the bodies from a neighbor's shed.

Prosecutors planned to show the four and a half hour video of this confession in court Friday, but jurors didn't want to stay late. Prosecutors said they'd revise their plans and show the video on Monday.
