Tennessee toddler went missing in December. Authorities want to know why her parents didn't report her disappearance until this week.

Fifteen-month-old Evelyn Boswell has reportedly been missing since the day after Christmas, but her family only just reported the toddler's disappearance on Tuesday, according to authorities.

On Wednesday, the Tennessee Bureau of Investigation requested that the Sullivan County Sheriff's Office issue an Amber Alert for the missing child.

What are the details?

The Tennessean reported that investigators are attempting to determine why the child's family took so long to report her missing.

Tennessee Bureau of Investigation spokesperson Leslie Earhart announced Friday that the child was last seen wearing a pink tracksuit, pink shoes, and a pink bow. Evelyn stands 2-feet tall and weighs 28 pounds. She has blonde hair and blue eyes.

On Friday, the bureau tweeted that individuals in a "gray 2007 BMW with TN tag 3M9-6W9 have information regarding Evelyn Boswell's whereabouts." The bureau pointed out that the vehicle has front-end damage.

Anyone with information on the child's disappearance or whereabouts should call 911 and report and details about the case to 1-800-TBI-FIND.

What else do we know?

According to WATE-TV, a Blountville, Tennessee, man told authorities that he dated who he claimed was the child's mother — Megan "Maggie" Boswell — for a few weeks, but never saw the child.

"All I've seen is pictures of [the child], I've never even seen the baby," the man, identified as Hunter Wood of Hunter T's Chicken Shack, told the station. "I have no relationship with that child whatsoever."

Wood said that he met the woman when she applied for a job at his restaurant.

Wood added that the child was staying with a man he identified as her father — Ethan Perry — in December. Perry was reportedly home on military leave for the Christmas holiday.

"While Evelyn's father, Ethan, had the child, the baby, you know, fell off the bed and broke her arm, and he took her to the hospital," he added. "That's what I was told."

"They have half custody to the best of my knowledge," Wood continued. "It's not my business to dig further into that because we weren't that serious for me to dig further."

He added that he only wants authorities to find the child.

"I'm not doing this to, you know, hurt this investigation because all in all the entire matter here of what's going on and what needs to be resolved is finding that baby," he told the station.
