BLOUNTVILLE, Tenn. (AP) — A Tennessee teenager has pleaded not guilty to felony murder and other charges in the death of her 15-month-old daughter, whose disappearance prompted a search across three states.

Megan Boswell, 19, wore a mask as she appeared via video briefly Friday for an arraignment in Sullivan County Criminal Court, news outlets reported. Her attorney has also requested a change of venue for the case.

The remains of Boswell’s daughter, Evelyn Mae Boswell, were found five months ago inside a shed owned by her grandfather.

A family member reported the child missing on Feb. 18 though the child had not been seen since December, the Tennessee Bureau of Investigation said.

Boswell initially told state investigators that her daughter was with the child’s father, who is stationed with the Army in Louisiana, but he did not have Evelyn, media reported. Boswell later said her mother took her daughter to a campground in Virginia, but authorities found no sign of the girl there.

A Sullivan County grand jury indicted Boswell last week on two counts of felony murder; one count each of aggravated child abuse, aggravated child neglect, tampering with evidence, abuse of a corpse and failure to report a death under suspicious, unusual or unnatural circumstances; and 12 counts of false reports.
