KANSAS CITY, MO (KRON) — A mom was shot and killed during a road rage incident as her two young sons watched from the back seat of the car.

Whitney Gray was 22 years old and had two sons, a 6-month-old and a 3-year-old.

“She was the best mom I knew,” Dylan Gray said about his sister Whitney. “I’m angry. (sighs) It doesn`t make any sense to me.”

Witnesses say Whitney got into a road rage incident with Christopher Taylor before being shot.

According to court documents, Whitney’s 16-year-old niece threw out some type of liquid onto Taylor’s SUV when he pulled beside the family’s car. Taylor tailgated and followed Whitney so close that he almost caused a wreck.

Moments later, Taylor allegedly pulled out a gun and shot Whitney in her chest as her young sons watched.

Taylor is now facing second-degree murder charges.CNN Newsource contributed to this report
