Tia Carey, a 21-year-old beauty and mother of two, was shot and killed recently by her ex's new girlfriend. 

The lovely 21-year-old was shot twice outside of a gas station earlier this month by the girlfriend in Washington D.C. area. Unfortunately, one of the bullets pierced her skull and she was later pronounced dead at the hospital.

Tia's mother told the local NBC News, "She was only 21. So young. She didn't even get to see her baby grow up."

Tia was the mother of two girls, a 5-year-old and a 2-month-old. Tia's mom is now taking care of her grandchildren.

And the circumstances surrounding her death are equally sad. Tia got into an argument with her baby's father's new girlfriend. The new girlfriend, 21-year-old Tierra Posey, confronted Tia - and the two got into a physical fight.

Police say that Tierra pulled a gun and shot Tia in the head, then tried to flee the scene.

Witnesses said they had to physically sit on top of the suspect, Tierra Posey, to keep her from running.

D.C. police arrested Tierra and charged her with second-degree murder while armed.
