A Colorado Springs family is mourning the loss of a daughter, a woman who also leaves behind a young daughter.

Lilly Duncan, 31, was killed last weekend in a wrong way crash on Interstate 25 and police say the driver who hit her was drunk.

Now her mother Diana Smith is telling her daughter’s story.

"I got the news that my daughter was killed in Denver by a driver going the wrong way on the interstate, it’s just like how can that happen,” Smith said.

Lilly Duncan was killed on May 14. Police say 26-year-old Victoria Barry was driving south bound in the northbound lanes of I-25 near downtown Denver.

Diana says because of the actions of one person her family has been torn apart, and Lilly's 12-year-old daughter Dyrah will grow up without a mother.

"She's not going to be there when she gets married, or has a baby,” Smith says.

Dyrah is no stranger to tragedy. Her father was killed when she was only 9 years old and still with everything she has had to endure she’s thinking about others.

"Even though the girl did a wrong thing that doesn’t make her mean," she said.

Victoria Barry, the accused drunk driver, was injured in the accident. She was released from the hospital on Friday and arrested for vehicular homicide, reckless driving and driving under the influence. Formal charges are expected to be issued this week.

Lilly Duncan’s funeral is set for Monday afternoon in Colorado Springs.
