Authorities are awaiting autopsy results after remains of a missing 15-month-old girl were believed to be found in Tennessee.

At a press conference Friday night, the Tennessee Bureau of Investigation and the Sullivan County Sheriff’s Office said they believed they found the remains of Evelyn Mae Boswell earlier that evening.

The discovery appears to end a 17-day search across three states for the missing toddler. An Amber Alert was issued more than two weeks ago, but authorities have said she hadn’t been seen since at least December.

The remains are being sent for autopsy and positive identification, Sheriff Jeff Cassidy said. Authorities acting on a tip found the remains on a property in Blountville that is owned by a relative of Evelyn’s mother, the sheriff said.

The TBI and the sheriff’s office did not provide updates on the investigation when contacted by email Saturday.

Evelyn’s mother, Megan Boswell, 18, was arrested Feb. 25 on a charge of filing a false report. Authorities said her inaccurate and conflicting statements had impeded the investigation.

She initially told state investigators that Evelyn was with the child’s father, Ethan Perry, according to court documents from her arraignment. But Perry is stationed with the U.S. Army at Fort Polk, Louisiana, and did not have Evelyn, WJHL-TV reported.

Megan Boswell later said her mother, Angela Boswell, took her daughter to a campground in Mendota, Virginia, not far from Tennessee’s Sullivan County. Authorities searched multiple campgrounds in that area and found no sign of the girl, the TV station said.

Angela Boswell herself was arrested the week before her daughter was taken into custody. She and her boyfriend, William McCloud, were arrested in North Carolina on fugitive warrants unrelated to Evelyn’s case, authorities had said. Authorities looking for Evelyn searched a pond in the county where they were arrested.

Angela Boswell told a judge in North Carolina that she wanted to go home and resolve the situation with her granddaughter, news outlets reported at the time. She was subsequently returned to the Sullivan County jail a day before her daughter joined her there, and arraigned on a theft charge.

Bail for Megan Boswell remains at $25,000 after a judge rejected a request to lower it from her lawyer, who cited her lack of a previous criminal record. The lawyer waived a preliminary hearing and the case was sent to a grand jury, with her next appearance scheduled for early May.
