BLOUNTVILLE, Tenn. — The grandmother of a missing toddler and her boyfriend have each faced charges of domestic violence, a Knox News review of court records shows.

Angela Boswell, 42, of Kingsport, was arrested along with her boyfriend, William McCloud, late last week on car theft charges — accusations authorities used to get the pair into custody.

The Sullivan County Sheriff's Office, along with agents from the FBI and Tennessee Bureau of Investigation, want to question them about Boswell's missing granddaughter.

Authorities believe Boswell's granddaughter, 15-month-old Evelyn Boswell of Blountville, vanished sometime in December. The toddler's grandfather, Tommy Boswell Sr., reported her missing Feb. 18, officials said, saying certain family members hadn't seen her in two months.

Evelyn's family members — including her 18-year-old mother, Megan Boswell — have given conflicting, changing statements to authorities. Megan Boswell was taken into custody Tuesday night.

Tommy Boswell Sr. has accused the toddler's grandmother of violence twice: once in an order of protection application and once in a criminal warrant, a Knox News review of Sullivan County court records showed.

The warrant alleged the toddler's grandfather came home from work with no food in the kitchen in March 2009 and asked Angela Boswell for a set of keys so he could go get some.

"Angela then started yelling at him ... grabbed Tommie by the neck and grabbed an ink pen and shoved it into his neck," the warrant stated.

The alleged attack occurred in view of the couple's then-teenage son. The warrant alleges father and son fled as Angela Boswell continued assaulting her husband, grabbing his hair as he ran out the door.

She later struck a deal to have the charge dismissed so long as she didn't get into trouble. She did, though. She racked up charges including stealing and trying to sneak drugs into jail. She was accused twice of driving on a suspended driver’s license with unidentified children unrestrained in the vehicle each time.

McCloud, court records show, is under indictment for allegedly attacking another girlfriend in July 2018.

In that case, McCloud is accused of choking his girlfriend repeatedly until "her vision became white and blurred," grabbing her hair and slamming her face onto the ground, punching her and biting her ear.

He is also facing a grand jury review of charges he attacked the same woman in September 2019, punching her in the jaw and face, hitting her in the stomach and knocking her down.

With little else to go on, investigators are imploring anyone with information about Evelyn to call 1-800-824-3463 (TBI-FIND).
