A young Woodbridge woman was shot and killed Tuesday when her boyfriend pointed a gun -- which he said he believed was empty -- at her and pulled the trigger.

Brittney Koster was 25 years old and an avid softball and volleyball player.

"She's just a girl that everybody loves," said Patrina Stoeckel, Koster's softball coach. "She was always upbeat, always smiling. She is always there for somebody."

Koster was with her boyfriend, David Williams, at his home in Rappahannock County when the shooting occurred. Williams told investigators he thought the gun was empty when he pointed it at Koster and pulled the trigger.

Williams, 22, has been charged with involuntary manslaughter.

"How she passed is very hard for everybody to understand," Stoeckel said. "You don't ever pick up a gun and point it at anybody."

Koster's friends told News4 that they are skeptical of Williams' story. Samantha Dodson, one of her close friends, said Koster was trying to break things off with Williams -- and added that she has text messages from Koster that she'd like to show investigators.

"I do think he tried to scare her into staying with him," Dodson told News4. "From the messages that I've personally seen, I think maybe he put fear in her," Dodson told News4.

The victim's friends hope Williams may eventually face stiffer charges.

"I hope that he gets charged with murder," Dodson said.

News4 was not able to reach Williams or his lawyer for comment.

For now, the friends are focused on a memorial for Koster on the softball field Saturday. It will center on second base, where Koster often played. They've also started a GoFundMe site to help her family with expenses.

"She was the most selfless person I think I have ever met in my whole entire life," Dodson said. "And I want everybody to know how many people that she touched, how many hearts she touched."
