CLIFF NOTES from the court documents below: 
The deceased (Tia Carey) was out riding around with her Aunt with their children in the backseat. She spotted her baby father's car at the gas station and told her aunt to pull over. She got out and confronted him while he was pumping gas and an argument ensued. Tia then went to his passenger seat and tried to pull his girlfriend out but the girl closed the door. Tia got in the car through the back seat and punched the girlfriend (and also spit on her at some point). The girlfriend got out and they started fighting (allegedly the Aunt jumped out and threw a punch too).
The baby father pulled Tia back and the girlfriend got back in the car, got a gun, got out and shot Tia in the head. The baby father grabbed his girlfriend, took the gun and put it in his pocket and jumped in Tia's Aunt's car and pulled off leaving his girlfriend (apparently he fled to take the kids, one of them is his and Tia's child, away from the scene). The girlfriend jumped in his car and tried to pull off but the Aunt and one of the kids (whom is a teen) jumped in and sat on her until the police got there.

A woman fatally shot another woman in the head outside a gas station in Northeast D.C. on Monday, police say.
The shooting happened outside the Valero gas station at Minnesota Ave. and Ames Street NE shortly before 4 p.m., D.C. police said.
Medics rushed 21-year-old Tia Carey to a hospital, where she later died.
"She was only 21. So young. She didn't even get to see her baby grow up," Carey's mother, Demaris Carey, told News4 on Tuesday.
Carey was the mother of two girls, a 5-year-old and a 2-month-old. Demaris Carey is now taking care of her grandchildren.
"Senseless violence. I mean, you know, we encountered things every day… situations, but this was just an act of senseless violence," Demaris Carey said.
Witnesses and family told News4's Pat Collins that Carey had picked her daughter up from school and stopped at the gas station to get something to drink. They said she then got into an physical argument with the suspect, 21-year-old Tierra Posey.
The women were throwing punches at each other and then Posey allegedly took out a gun and fired two shots.
Witnesses said they had to physically sit on top of Posey to keep her from running from the scene.
D.C. police arrested Posey, of Southeast D.C., and charged her with second-degree murder while armed.
