For 36 years, James Frank said his Morristown neighborhood has been a quiet one. That changed just before 8 Wednesday night.

"Just bang, bang, bang - and that was it," said Frank.

Frank heard the gunshots that killed Joseph Weeks, who lived just down the road from him.

Police Chief Roger Overholt said a child in the home called 911 because Weeks was threatening to kill himself. When they arrived, they found Weeks with a revolver and managed to calm him down, but then his girlfriend, Alkini Thompson, began fighting with him.

"At that time, they began to struggle. Mr. Weeks still had the firearm in his hand. An officer, fearing for the safety of Mrs. Thompson and for others on the scene - officer Dustin Jones - fired two shots, which both struck Mr. Weeks," said Overholt.

Then , officers arrested Thompson. She's charged with abusing her daughter and with making threatening calls to her estranged husband and his girlfriend.

"Allegations of striking the 12-year-old because she believed the 12-year-old had called for police," said Overholt.

After that call, Overholt said the12 year old and another child were placed in temporary emergency custody.

"It's a shock. I mean, I never had a conversation with the people - their little girls used to come up here and play with my kids but never had a conversation with the parents, but no worries or nothing like that. But yeah, it's a shock," said Chris Ewing, who lives three doors down.

Overholt said officers can use deadly force when there's a threat of death or great bodily harm. Now, the TBI is investigating to make sure they followed that policy.

Thompson's bond is set at $6,000. She's expected in court Friday.
