Wow! From your link:
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.
